As some of you may or may not know, we here at PERRIN have taken on a little project called Project $15K (http://forums.nasioc.com/forums/showthread.php?t=1371832). This is where we take a 2002 WRX and build the ultimate daily driver. After washing it and cleaning everything up it was time to change out all of the fluids. While doing this we decided that we should install our SLS.

Adding the PERRIN Subframe Lockdown System adds rigidity and stability to the rear end diff. This kit eliminates all driveline slop and the annoying thud that can be heard shifting from first to second. The results can be felt the first time you take off from a stop light at almost any speed. I have to say that this has to be one of the best “bang for your buck” mods I have ever done. For more information click here (http://www.perrinperformance.com/products/show/278).

Needed tools:
1) 12mm socket or wrench
2) 17mm socket or wrench
3) Jack and Jack stand

Step 1) Raise the vehicle to a desired height allowing you enough room to move freely. For this you will want to use jack stands to support the vehicle while working on the cross support. NEVER WORK ON A VEHICLE SUPPORTED ONLY BY A JACK.

Step 2) Time to remove tension from the differential, this will allow you to lower the differential stabilizer. You’ll need to get a floor jack for this next step. Placing the jack under the differential you’ll want to raise the differential roughly .5”.

Step 3) Using a 17mm socket remove the 17mm nuts securing the differential to the cross support. Remove the studs from the differential and the cross support by using the “Jam-Nut” method. (this is where you “jam” two 17mm nuts together on one stud. Then you can remove the stud by unscrewing the nut closest to the differential). Repeat this process on the remaining stud. If this method doesn’t work you’ll have to use a stud-extracting tool.

Step 4) Once the two studs are removed from the differential and the cross support you will remove the two 17mm bolts and nuts securing the differential stabilizer to the rear sub frame. Its now time to lower the differential, you will only need to lower it slightly to allow for clearance. If needed you may want to remove or lower the exhaust system allowing your self even more working room.

Step 5) Remove or lower the differential stabilizer from the sub frame. After you have done this you can install the 4 smaller red urethane bushings around the OEM Bushings center mounting points. (2 bushings installed on each side)

http://i268.photobucket.com/albums/jj39/PERRIN_Ken/Project%2015k%20Rear%20Diff/Project15K031.jpg

Step 6) After all 4 of the PERRIN bushings are in place you can now reinstall the differential support brace into the chassis. (Don’t fully tighten just yet)

Step 7) Raise the differential back into the car, line up the stud holes with the differential support holes and reinstall the studs.

Step 8) Tighten the differential stabilizer support bolts to 70ft-lbs. Now go back and tighten the nuts on bolts on the sub frame to 70ft-lbs.

Step 9) Time to install the rear sub frame lock out bolts. You’ll want to locate the empty threaded holes on the rear sub frame. Screw the bolt and bushing into the empty hole on each side of the car. Tighten the bolts down to 60ft-lbs. (BOLTS AND SPACERS MAY MAK SOME POPPING SOUNDS WHILE THE BOLTS ARE BEING TIGHTENED INTO THE CHASSIS, THIS IS NORMAL)

http://i268.photobucket.com/albums/jj39/PERRIN_Ken/Project%2015k%20Rear%20Diff/Project15K017.jpg

Step 10) Locate the differential front support beam and the 2 outer bolts securing it to the chassis. Remove the passenger side large bolt securing the front support beam to the chassis, and the two bolts securing the plate to the chassis.

Step 11) Pull down the front support brace until there is enough room to place the new bushings on top of the OEM bushings.

Step 12) Reinstall the plate back onto the chassis and tighten the 12mm bolts to 25ft-lbs. Install the large 17mm bolt through the bushings and tighten to 100ft-lbs.

Step 13) Repeat step 10, 11, and 12 on the drivers side.

Step 14) Lower vehicle and test drive.

kk i failed miserably at installing the screws, i wasn't able to loosen the 2 bolts. do i need to have the car lifted or can I use ramps?

i used a ramp and couldn't loosen it.

Hey there
I hope this can be of some help? First off you don’t have to place the vehicle on jack stands. You can park it on ramp’s, however I personally feel a little more safe if the vehicle is being supported by stands.

Once you remove the studs on the differential and remove the bolts on the cross support everything should be loss allowing you to lower the diff and the differential stabilizer. If you have any questions feel free to give me a call.

Happy Holidays

Jeff tried both on his personal WRX's. He found little performance improvement when he made them completely solid but had higher levels of NVH. Hence the reason he designed the kit in this fashion. Should work great on strip, street or rally. I am personally amazed at how differently the car FEELS when driving it with this inexpensive mod.

Assuming you have the right tools and oil ready to go. Most clients would be done within an hour or two MAX. Very straightforward to install.

Hope that helps!

i mean i am looking at both installs and the perrin loks like it is for the rear and the whiteline and kart boy are for the front it seems to me cause on the whiteline install guide it says nothing about the rear diff its all for the front

Got it now! Different product. The PSRS from PERRIN goes on the front. Click HERE (http://www.perrinperformance.com/products/show/274/Positive-Steering-Response-System?category=8&model=18)!

VS.

The subframe lock down shown in the DIY above.

Each product does a different thing. The PSRS is an anti-lift system for the front suspension under braking and hard acceleration. Plus with the additional caster angle it dramatically improves steering response. (Hence the name Positiver Steering Response System.)

The rear subframe lockdown system prevent axle trounce, driveline lash, improves throttle to drivetrain control etc.

Thank you for the follow-up question!

Adam.Taft@perrinperformance.com

oooo so the whiteline and kartboy kits are just a step blow the psrs system? instead of the psrs peice they use bushings? is that what you are telling me? and would it be wise if i made my own bushings for the rear diff bushings inserts because i have left over polyurethane bushgings from my energy suspension kit i got for my old car and im pretty sure if i trimmed them down i could make them fit do you think this would be wise?

Finally got around to installing mine last night. I love it!!! Easy install and small investment for a huge return in the feel of the car. Infreakincredible.

First part yes that is correct.

Second you should be just fine. As long as you can get it to fit that is ok. You will be missing all of the metal piece to lock the subframe, but other than that you are a-ok!

Are you going to offer this for 2008+ Impreza? If so it should also fit 2005+ Legacy. Supposedly all the bushings are the same.

ive had a list of parts of parts im working twords. its large. this rear subframe lockdown was on the list and now that its on sale i ordered it . let the suspension work begin . this is my first step in rear . next comes larger sway bar , end links , mounts, lateral links, trailing links , assorted chassis stiffening bars ,well see how it feels after all that in the rear if its too loose still ill look at coilovers. i just cant see swapping out the stocker struts and springs yet cause they still work . once they go bad ill upgrade , but we will see how other mods affect performance first.

anyone know the answer to this????

From what I understand, this is the bolt you're talking about. I'm pretty sure the bolt just locks down the subframe and doesn't allow the diff to clunk around.

http://i268.photobucket.com/albums/jj39/PERRIN_Ken/Project%2015k%20Rear%20Diff/Project15K017.jpg

What can I do if the threads that the subframe bolts are screwed into are rusted off?

ATK: That is correct. That is bolt / shim combo right there. Prevents the subframe from jouncing around!

Spike700: I may be missing something in the question, but my opinion would be to clean them and re-tap them. Should be a relatively easy affair. Let me know if I missed something!

Adam.Taft@perrinperformance.com

sweet , thats exactly what i thought it did . so what the bolts are . they are lock down bolts. i was just concerned they locked the rear diff . but i think welding is the only way to hook that up. just trying to be as informed as possible thanks for the clarification.

Thanks Adam,

No you didn't miss anything. The threads are rusted out on my car so I was just wondering if there was something I could do. Thanks for the advice.

installed this this past weekend. There is a circular piece of metal above the forward crossmember/brace, in between the stock rubber and the chassis....

Its not described/referenced in the instructions.. is this removed, or does the urethane bushing go on-top-of or below?

same thing here man . on one side i put the plate underneath. on the other i put it on top.

when i put the second side together it was obvious the metal plate goes on top of the red bushing. i went back to the otherside and the metal plate was all bent up cause i put it on wrong. after fixing it and tightening everything up im pretty sure it bent back into place. it feels fine. next time i hae the car up on ramps or stands ill recheck everything.

YES the metal plate goes on top. Good point on the instructions, thanks.

I'll have our instruction man look at it to see how we can illustrate that.

From what I understand, this is the bolt you're talking about. I'm pretty sure the bolt just locks down the subframe and doesn't allow the diff to clunk around.
http://i268.photobucket.com/albums/jj39/PERRIN_Ken/Project%2015k%20Rear%20Diff/Project15K017.jpg
Ya, those bolts, need to be tightened. In that position the subframe will not be locked down. Just crank'em down!

YES the metal plate goes on top. Good point on the instructions, thanks.

I'll have our instruction man look at it to see how we can illustrate that.



Dammit! I just got around to installing this weekend, and was asking myself the same thing. I put bushing on top of plate because it didnt seem like the plate was going to sit flush against the chassis (I didnt notice it was there until it was fully disassembled).

Luckily though the install was very easy. My wife was amazed as it was the first time I told her I would be back in from the garage in an hour, and I actually was.



As a tip, I know a lot of people talk about the lockout bolts not threading in correctly. I took a tooth brush, which fits up there perfectly, and some cleaner and scrubbed the threads out well, and then blew them out with some air just to be sure. I also put a bit of lithium grease at the start of the bolt threads to ease the start. Both bolts went in nice and easy (finger tighten first for sure).

how much does NVH does it make?

how much does NVH does it make?

Very little. The biggest change you might notice is on expansion joints in the road. Others in this thread may be able to better relay their experiences now that they have the system installed.

Thanks for asking!

Adam.taft@perrinperformance.com

I have only been on it a few days, but what I can say is that overall NVH is minimal. However, if you hit a pothole or something else in the road with the rear wheel, the sound transmission is much greater than stock.

Just installed this kit. Only kind of hard part was aligning the bolt holes after installing the bushings on the differential stabilizer. Overall not a hard install at all.

I installled this kit on my 05 wagon last spring and I love it. The install was easy with jack stands and hand tools. The car immediatly felt much more solid. You really feel the acceleration and it's much easier to be very precise with steering, braking, and acceleration. I highly recomend it. The NVH isn't that noticeable and it's kind of nice to hear the car.

I really like the idea of this kit... I drive an '00 RS, but I drive it hard as hell and beat it into the ground off road....sometimes litterly, that's why I keep a winch.... So after 150K, it's easy to understand why I get those jolts not just in first and second, but also third... I've always known there to be alot of unwanted slop in the driveline, but I also know there's alot of rust....So I guess I'm just skeptical about doing this mod, because my rear end is held together by frozen bolts.

Uh, I guess my two questions are, after seeing this thread just now, is that sale still active, and also....You guys have any suggestion for if I break/ and forced to destroy bolts? Like, can you guys at least supply me with some dimensions so I can run by the hardware store and get new ones?

Well both and then some. The clunk is a biggy for sure that is eliminated. The throttle control is the next thing in my mind, as the slop is gone, thus the throttle input is more immediately felt through the car. Finally the control of the rear suspension is improved.

Hope that helps! Let me know!

I installed the kit and I have one concern. I can feel the ring and pinion gears meshing in 2nd and 3rd gear right around 3500 rpm. I am wondering if this is normal.

I am wondering if I have installed the front bushings correctly (the 2 largest bushings in the kit. I installed the bushings on top of the support beam and mounted the plates on top but the bushings never seemed to seat flush in the mounting location. They seem to be bulging out. Does anyone think this is causing the gear vibration I am experiencing?

Other then that I love the Perrin SLS!

I too just tossed in the Kit.

Install wise, all went well on the bushing part of the task, but when it came time to throw the bolts in....things changed.

I finished up the rear diff bushings, tightened the nuts back up, and went onto installing the two "Lock-down Bolts" (the Grade 12+ Monsters included with the kit.). I put one in the proper hole, tightened by hand for a turn or so, then moved on to handtools. After a few turns I noticed there was no more tightening, just spinning.

So, something broke. I know the hole is not stripped as I had threads going in, and I cannot remove the dangling bolt now. My questions are: were the threads we were utilizing for this kit (the inside of the Factory hole) simply a nut welded onto the other side of the frame? Also, were do I go from here?

Im left with all the bushings installed. One lockout bolt in my hand, and the other dangling(yet not coming out) halfway into the frame.

I finished up the rear diff bushings, tightened the nuts back up, and went onto installing the two "Lock-down Bolts" (the Grade 12+ Monsters included with the kit.). I put one in the proper hole, tightened by hand for a turn or so, then moved on to handtools. After a few turns I noticed there was no more tightening, just spinning.

So, something broke. I know the hole is not stripped as I had threads going in, and I cannot remove the dangling bolt now. My questions are: were the threads we were utilizing for this kit (the inside of the Factory hole) simply a nut welded onto the other side of the frame? Also, were do I go from here?

Im left with all the bushings installed. One lockout bolt in my hand, and the other dangling(yet not coming out) halfway into the frame.
Well that about stinks! But it is a good lesson. These threaded holes are uncovered at the factory and thus subject to all kinds of crud and junk going in there. It is an EXCELLENT installation procedure to clean and possibly chase these threads prior to installation of the supplied bolts. Also, double check them against those supplied in the kit to be sure they match. There can always be an error made, or change in the vehicles as well.

I hope you can get that out of there, cleaned up and back in business ASAP.

Ring Jeff or I tomorrow if we can help in anyway. Thanks again!

Hmmm... I guess the whole rear is coming off then.

Wish me luck!

I still dont understand why this happened. The only reason I can guess is that the Subaru factory threads arent always welded to 100% potential on something they didnt plan on using. I know a weld broke in there, that has to be the situation, but I cant see why other than poor manufacturing. The threads were cleaned with PB Blaster, Simple Green, Brushes and Compressed air. The Bolts threaded in easily until they stopped tightening. Am I losing faith in Subie now...?

Yeah that is just weird. Sorry you had that happen at all!

Any chance of this fitting older Foresters? Say, a 2002?

Kurlon,

The rear diff cover should fit, but the subframe lockdown won't because the subframe is different. Thanks!

Ok, so I was under my car today and it seems my rear subframe is a little different. I have a 2000 2.5RS with a diff. cover that was there when I bought it. I don't know if that makes a difference, but basically, mine varies, for whatever reason, from both your and my manuals pictures of what it should look like. Where those two center holes in the subframe that are close together are, that's where my bushings are, and how the diff connects to the subframe. I don't have that little "arm" that holds the bushings AT ALL. I'm wondering if these bushings will work for me and was wondering if I back that nut off on mine, is it just a stud that goes into the diff, or what? if so, how do I get your inside rear bushing on the stock bushing? Finally, would anyone be willing to measure those bushings for me so I can see if they'll fit?

That nut is rusted on there dame good, so I kinda want to know what that stud it's holding connects to on the diff, and how... Thanks...

I'm 99% sure your car is just like the WRX, but if you could take a few pictures of your car under there we can help you out from there, thanks!
