Rear End Feel

[blinkwatt]

I don't think anything is worn. I had a PPI done and my car has seen two mechanics,1 was a family friend who would have said anything if he saw anything wrong. All of which was done in the last 2k.

I'm just starting to think this is how the car is. I just thinks it's a combination of;

-extra power I'm not used to

-I'm just really on edge since I spun out my last Boxster

I'll push it really hard next time I'm driving, I just think I need to get used to it. The back end hasn't gotten loose on me,nor has it done anything that would seem unusual.

You should consider supporting your PCA autocross events. Its a great place to get some free driving tips, improve your driving and have a blast while doing it. It is also very safe so that when you do loose control, the worst that will happen is killing some cones, a few scuff marks that will usually buff out, and a bruised ego.

That is something I WILL do this season. I tried to make it to Alameda Point but was too crammed with Mid-Terms and such for college.

I experience two quirks with the rearend of my car. The first is similar to what you describe. It is most noticeable on the track just past the apex on a turn that requires a sharp turnin. The rearend does kind of a "jog". It comes right back but is a little unnerving. I have 17" wheels and the tires do have some sidewall flex which is what I have attributed most of this to.

Secondly, upon very hard acceleration the backend kicks to the side as I shift from first to second gear. You can really feel the torque from the drive wheel and again can be a little bit unnerving. I attribute this to the lack of a limited slip diffential. I have contemplated whether a LSD would also help with the first issue I described as well. Any thoughts from those who have LSD on how it changes the rearend feel? Is LSD a waste or would it help?

I experience this same problem... It is on the shifts, and especially moreso, on a downshift, that one side tends to squat more than the other. I was wondering if it had to deal with lack of LSD also. Recently I installed a set of adjustable aftermarket rear trailing arms (track arms, as some call them), with the spherical bearings rather than the OEM rubber bushings, and that seemed to have helped a little bit, but I still get some of that same feeling on the shifts/downshifts. I am wondering now, since the addition of the spherical bearing type arms helped to eliminate a bit of that play, that perhaps it could be an issue with the motor mount bushings perhaps? What do you guys think?
