Stock catback exhaust, stock rear swaybar, quad shocks, quad shock brackets, bump stops, ABS sensors, and stock rear springs can be included if needed for somebody going to this from IRS.

Rear was installed in the car 1 year and 2 months ago, when I installed it I traded my stock geared rearend for it, and immediately after install I noticed a very mellow gear whine on the freeway, it has not gotten any better, or any worse since that day. I think it's related to the MM lower control arms poly/spherical bushings setup transferring gear noise into the chassis.

About 6 track days and 6 months into that, the rear developed a clunk on/off throttle and between shifts. I honestly don't know how bad it is, but I've daily driven the car every day for the past 2 years and it hasn't gotten any worse, I noticed it after an autocross, I think I caused the pinion crush sleeve to collapse but I'm not sure, I'm more of a nuts and bolts guy, not a mechanic so I really don't know how to diagnose it, all I know is the driveshaft has some play when I jack the rear of the car up.

There's no vibration, and if I didn't have stock mufflers and stock 6 cat "smogginator" midpipe on the car, I doubt I'd be able to even hear the whine or clunks that it makes, the clunking sounds the same as my buddies T3650 in his 2000 GT does when he shifts it to 2nd. I'm extremely anal with my cars, somebody else might not care about it, and if this is going into a track car it's a non-issue, just warning anyone that would want this in a DD that it isn't 100% perfect.

Or asking $700 for everything, I'm putting an IRS in the car as it's turning more and more into my autocross whore.

(ignore the tokiko's, they were recently replaced with the above mentioned bilstein shocks)

I've purchased and picked up my IRS, so this is being removed from my car this weekend.


If you want to hear/feel how this runs in my car, I'm driving it to work all week in Camarillo...


Here's a couple videos that shows how the gears sound on the highway.
