Default STi GroupN Transmission Mount Review

Damn, where to start... had this sitting around a few weeks waiting to install it, thinking.. hmm, maybe i shoulda got the IPD rearsway bar instead. But what the hell, so after mucking around with my brakes all day I got around to installing this beast. right outa the box it felt beefy and strong but not that impressive. but its a tranny mount, how cool is it suposed to look. The install was smooth, ratchet with 14mm deepsocket was all the tools, It does help if you put a jack under the tranny or exhast cause when you remove some of the skidplates/cross members it does start to sag some. but 30 min later and ready for a test drive. I noticed a huge diff just starting up the car, where before my whole motor and tranny would shake and i could feel it though the shifter. Now, no shaking. Feels nice and tight. When i step on the gas everythng just feels more solid and shifting is much nicer now, less slop and engine feel though the shifter. I did notice a little more vibration, prob due to the stiffer mount, but hell i'll either get used to it or it will wear in a little.

overall, not a flashy mod you wanna show off to everyone but if you have $70 laying around and want something to add to your rig, Its a good mod.

I've been thinking about doing this, but I heard installation was PITA. This makes me wonder if it isn't easier...

did you even jack up your wagon, or just used a jack to keep the tranny up?

Mounts may not help you produce more power, but they'll help you waste less of the power you're already producing

well my outback is about 5inches off the ground.. (still needing to fix that) so yeah i had to jack the front and put it on stands. It was pretty easy to install even easier with more ground clearance. the 2nd jack was mostly for the exhaust cause you have to take off one of the supports and it wants to drop on your face. heres the breakdown

4 bolts to remove the braces and 4 to remove the mount from the tranny then 2 more to remove the tranny mount from a skidplate. easy as pie.

I've heard that this + STi motor mounts really reduces the play in the drivetrain that our cars suffer from.

Yes. They do.

I've got engine, tranny and pitch stop STi mounts. Its the easiest way to get a massaging drivers seat. I'm kind of used to it by now, but when you stab the throttle, you feel it even better.

One of the best mods I've done. no regrets.

Can't wait till I put in some stiffer bushings for the rear end...that'll compliment the front STi mounts rather nicely!

Great mods, and very easy installations. I'm not sure who said the tranny mount was a PITA as it is one of the easiest things you can swap out on the car. With a hoist should take about 10-15 minutes.

I doubt it, but will the tranny mounts work for a 4EAT too?

I have all the STi mounts, but have only installed the pitch stop so far and all I can say is WOW. When I pulled off the old mount I could move it about 1/4" with just my fingers...try that with the STi!

If you're sick of the low speed lurch in traffic as you go on or off the gas grab an STi pitch stop mount. I got mine from hardcoretuning on eBay and was very happy with the price and shipping (plus it's the latest version of the mount).

Hopefully I'll have a chance to install the other mounts soon, though I'm not looking forward to wrangling with the motor mounts.

how much was the pitch stop mount? Letting off the gas in 2nd and 3rd gear has always been annoying because of that lurching.

Actually, can someone explain what it is, and where it goes?

I just checked and I paid $44 shipped for the pitch stop mount from hardcoretuning.

It's sometimes called a dogbone because of the shape, and mounts between the back of the engine block and the firewall, should take <15mins to replace.

update: ok so after driving a few miles last night, i love my new tranny mount even more. I have so much less engine movement and i really like the tighter feel. guess i have some more mods to ad to my list of mods. anyone swap out their crossmember mounts? I looks just like a big rubber hockey puck.

I know what you're talking about! That would be an easy one to do!

I've heard that the STi ones are plastic, and the Legacy ones are metal, how is this an upgrade? More flex=less jerk??

The dogbone itself is not the source of less flex, it is the rubber bushing inside the ends that flexes less. One maker here in Japan tried to make a dogbone with just hard polyurethane bushings, and that really was for competition use only - a major source of NVH from the engine with that one.

This bolts the engine to your firewall. On/off throttle moments has the engine backwards and forwards. When I hit 280whp, getting off the throttle abruptly when in the meat of the powerband would have my larger TMIC whacking the firewall. The uprated "dogbone" pitch stoppers help reduce that as well.

Cheers,

Paul Hansen
