While you're at it (Quaife, clutch, more??)
 
Hi, I am having a Quaife and a new clutch installed, along with all of the bushings I can find that can be installed while the front subframe is out. Is there anything else I should do while I am in there?

Looking at the Quaife, an Excedy clutch & flywheel, bushings for the engine, transmission, control arms, steering rack, sway bar, new differential bearings. Looking to tame wheelspin and tighten up the steering. I have coil overs, camber plates, pads & rotors.

Its my daily driver, but mostly short trips to and from work and around town. I can put up with additional NVH if it saves me two seconds on the autocross course once a month.

I could add a bigger front roll bar, but I don't think that would help put the power down. Will adding the LSD make adding the front bar more attractive? My balance is pretty good now - I can toss the rear end a little on trail braking, even with extra rear camber from the coil overs and autocross tires.

What am I missing, chassis wise?

Should I swap the 15% pulley for a 17%? I was saving engine mods for another time, but that wouldn't be a big added expense. The 15% is stone cold reliable, no belt issues whatsoever - I want to stick with reliable.

I'm not changing the final drive or anything.

Maybe change the tranny oil? maybe the supercharger oil?

Any advice? Appreciate it.

Quaife Install complete
 
Foster is back; and here's a quick review on the Exedy clutch. Don't buy it if you are a daily stop and go driver. This bad boy is not easy. The pedal is hard, the engagement doesn't start until the pedal is 75% up, and at 80% you are fully engaged. And with the new single disk/flywheel setup, the revs can change quickly. Felt like I was back in high school learning to drive my first 4 speed.
The Quaife keeps the inside tire from lighting itself aflame coming out of the corners, so it's doing its job well.
Changing all of the bushings to poly seems to snug the front end's response down a little better, although stock wasn't bad.
When's the next race? Can't wait to try out my new toys on the track!
