Default TiC Klunk Killer Review

Had this installed at a friend's garage with a lift. All bushings went on easy, only took about an hour in total. I lubbed all the bushings with lithion grease and torqued all the bolts to exact specs.

The result: Amazing. I can't detect ANY extra NVH, and the car feels awesome. The rear end no longer get squirmy when taking a tight corner, and the back end just feel to much more connected. Much easier to "feel" oversteer coming on. Also, the shifter is stiffer and the gears are more defined. The shift effort has increased slightly, but the shift feel much crisper, and its now very easy to find the gear I want.

BTW, I installed both the KB bushings and the TiC bushings.

ditto, but installer was factory-trained Audi tech, install went even quicker

agree completely

BTW, tech installed both the Whiteline differential bushings and the TiC differential mount bushings - used Kartboy install directions for the Whitelines.

Unlike Greg B, I do have some noise issues now. Can hear the gearing at work - which I don't mind at all. I also have some whine from the rear diff/axle that was not present before - very speed dependent, not overly loud but definitely there. once above 65mph the noise disappears, so obviously TIC and Whiteline have conspired to make me want to drive faster. I can live with that...

Car has just hit 60k, running Redline 75w90 in the rear diff - and of course it's a wagon so the noises I'm hearing may not be audible in a sedan w/less miles, different gear oil, etc. stock exhaust too - but not for long, so the whine may soon be drowned out by other sounds. and since I run RE070's, when driving on poor surfaces I can't hear anything but the tires

Not complaining, just pointing out that YMMV with the install of any bushings stiffer than oem. in any case, I'll gladly take the benefits of much more precise feel over a little more noise

I just installed the klunk killer combo on my WRX last week. This is one of those mods that I wish I had done a LONG time ago, like when I first got the car. I am very happy with the results so far

First I installed the outrigger bushings. They got rid of a lot of the slop in the rear and NVH went up some in the lower RPM range for each gear. Then a few days later I installed the diff bushings and this really helped tighten things up even more, especially during some harder driving. No extra NVH was added by the diff bushings for me.

I love how my car drives now...it feels so much smoother through the gears. I drive through a ton of traffic on my way to work and I spend a lot of time in 1st and 2nd gear. The car used to do a lot of bucking and jerking in the lower gears in traffic, even while trying pretty hard to keep in smooth. Now it's a nice smooth drive the whole trip. My girlfriend even noticed how much smoother my car drives, which really proved that this mod just wasn't one of those things that's "in your head", it actually works.

The NVH isn't bad either...I got the race version of these and I was a little worried that they would be a little too much for daily driving but they turned out to be great so far. I only feel more vibration through the lower part of each gear. To combat this I try to shift slightly later into the next gear than I used to and this has proved to almost eliminate any NVH I was getting at first. Installation was pretty easy too, just follow the instructions on the TiC website and you won't have any problems.

I definitely recommend the klunk killer bushings

I figured I would bump this old thread since I just put these (the race ones) in my 04 STi (68k)

My first impression on these with the first few shifts was that there was def some added resistance between shifts but they did feel a lot more solid and defined. After getting through the gears I def notices a lot more NVH than before, which was none. It is pretty random through different speeds/gears but it is very present. It is something that I can hear, even with my radio on a bit. Not sure if I am going to put up with this or not. I will drive for a week or so and see if I feel like dealing with the added noise.

Overall, I still have a clunk, I have increased NVH but the gears feel much more solid and defined.

I think the clunk that I am still hearing is something in the rear/center diff or a U-joint. This kit was just worth the $ to see if it would be eliminated before having it professionally looked at...

Anyone else have any input on these? I know there must be more of you guys running these!

This kit is not for low speed clunk that can come from needing to reset the lash on the rear diff. It's for the hard bang of stuff moving around on the high rpm/hard shifts.

If you are still getting a low speed clunk (like in a parking lot) see how much freeplay you have when turning the prop shaft (turn it until the wheels start to turn, and then see how much free rotation you have in the opposite direction. It should be very little).

Okay next time I jack up the car I will check for play in different areas. The kit def does tighten anything up.

Clint, how is the NVH with the step down from the race bushings? Is it worth the difference in driving

NVH is very subjective. Before you change them out again I would put the thin large OD bushing for the outrigger in place of the thick large od bushing.

If you go with the race kit like I installed last year, you WILL have an increase in gear noise. It doesn't bother me, but my wife has to speak a little louder in the twisties.....

The thinner ones are the ones that are installed right now. I def have bigger issues that must be causing the lower end clunking. This kit did def take care of the high speed ones tho! and the shifts are soo much better, a little stiffer, but better.

I installed these over the past 2 weekends. My time is very limited, so I got done what I could one weekend and did the rest the following weekend. Total time spent in driveway, from jacking car up to being 100% done was at most 3 hours. I have the race version, on R compound tires, everything else is stock.
NVH: didn't notice any more really, and if there is more, it's obviously not bothering me.
Install: rear diff bushings were easy and the instructions on their site were straightforward. I think the hardest part was getting the old bushings out, LoL. I could not get them to pop out for me, so I just got my drill and drill the crap out of the rubber until they popped out.
Kartboy outrigger bushings were similar, the online instructions TiC links to are great, and easy to follow. The only issue I came across on the install was getting the other side done. I got drivers' side done first, went around to passengers' side, and simply COULD NOT get that outrigger low enough to pull the plate off the top. A little ingenuity, and leverage provided by a huge screwdriver (referred to as BFS from here on), paid off. I wedged said BFS between outrigger and the lip under the side of the car (place you put jack stands), and pried. Got enough room to pop it out, and then stuck a 3" socket extension in there to keep the gap open. Greased up bushing, applied it to the plate, and got back under the car. Pried one last time with BFS to release the extension, slid plate with new bushing into place, and all was good from that point on.
NO MORE CLUNK! I'm still breaking in the car at the moment (2006 SGM STI with new engine/clutch due to failed oil pick up tube), but have hit a few 6k rpm shifts over the weekend (I've put 810 miles on new engine so far), and no signs of clunks yet. Real test will be next week when I finally pass the 1k miles mark, then am free to open this thing up again.

Glad you are happy. It's easier to install the outrigger bushings if you remove both sides at the same time. That way the carrier will drop down and give you plenty of access. Get the bushings in the start the bolts on each side hand tight till you get everything started. Then torque them to final spec.

TiC, I thought of that as I was trying to do the 2nd side. It was too late by then, and I decided to just pry harder instead of going back around to unbolt the other side again.

Wow, didn't realize I never posted a full review of after getting the motor broken in,so here goes:
Guys/Girls, if you have a bad noise from your car when you shift, I'd recommend this product. My klunks are gone, car is very responsive with short hard shifts. Used to have an odd sluggish feeling when I shifted, I'd assume that was the torque being lost through the drivetrain as it torqued. Since it can't move much any more, that's gone. I have not even had an inkling of a klunk since installing this. Best $70 I ever spent.

Install was easy and everything went in without a hitch. Install difficulty for the rear diff mount bushings 3/10. Install difficulty for the outrigger bushings 1/10. Me and my buddy followed the TiC install guide and had no problems. Combined time is about 2.5 hours with breaks. Mild NVH around 1700-2100.

First Day Impressions: This inexpensive upgrade makes shifting at high RPM solid and I no longer feel that brief lag when the gear is engaging, it's now a smooth transition. The rear end feels more rigid. Same as above poster, no more klunk in my trunk! Would recommend this part.
