Had a great weekend at Mid-Ohio. My instructor was fellow ti owner, Brook Harmon. I got more out of this weekend than years of instruction. Under hard braking the rear generally gets squirrelly. First thing Brook noticed was my air pressure. I was running 46# hot. Way too much. We lowered it to 40#. BTW-Tires are Toyo RA1. And I run Carbotech PantherPlus, front and rear. He suggested a less aggressive rear bad to change the brake bias. I stuck in there a set of Ultimate Axxis. A tremendous improvement on handling. And so simple to. No instructor ever took the time to go over air pressure when coming off the track or to discuss brake bias. The car was so much more managable. I had a blast on my final session. __________________ ...steven

cool. always good to get someone who is willing to take the time to go over the finer points. the fact that he also has a ti helps too i'm sure. interesting that it needed more front bias. i guess those who are/were worried about putting m3 front brakes on with stock rears then shouldn't have too much to worry about. glad you had a good time and learned more about the car! __________________ 1996 318ti, California package, 267k miles

It wasn't that I need more in the front. I needed less in the rear. I use 328 vented rotors and they stop just fine. I will get a mushy pedal after 3 weekends of driving schools. It is more than adequate.  __________________ ...steven

was the back getting close to locking up or what was causing the squirreliness? i would think one could bias it back more to the front with a change in rear pads like you did or larger front brakes and less brake pressure, right? __________________ 1996 318ti, California package, 267k miles

Yes. The rears needed to keep spinning slightly. Between the pads and R-Compound there was too much grip on the back. Another way would be to install a brake bias valve. I'm going to experiment with the Ultimates but will try Carbotech Bobcats since those are going to be my street pads. The nice thing about this it makes swapping pads at the track easier. Now I will just need to do the fronts. __________________ ...steven

sounds like you're getting your setup dialed in, that's great.
can you describe the "twitchiness" you feel in the backend since moving to all poly bushings back there? mine feels so much more solid and planted that i'm not sure what you're describing. what else do you have suspension-wise? __________________ 1996 318ti, California package, 267k miles

When I go over a bump or crest a hill the rear steps out a bit. A little more now with the poly subfram bushings.
I have Koni Adjustables with close to 200K miles on them.
I have 323ti sport springs, 110K miles.

single or dual adjustable konis? perhaps the adjustment can be tweaked to get the tire back in contact (if it's losing contact) quicker? i guess that would be the rebound.
i'll have to explore how well mine handles similar situations. i haven't auto-x'd or road raced mine (even before, let alone after the new bushings) so you have way more experience with your car and the changes it's gone through.
what front LCABs and ball joints are you using? not that it has anything to do with the rear, just wondering. what about rear upper shock mounts? __________________ 1996 318ti, California package, 267k miles

Single adjustables all around.
The front I have solid 95 M3 LCAB. I don't remember if they are centered or concentric. __________________ ...steven

hmmmm ... that and/or perhaps stiffer springs. you've certainly got some lean going on there. the question is, is it too much? which anti-sways do you have? poly or rubber bushings for those? __________________ 1996 318ti, California package, 267k miles

I have the stock bar and bushings.
I have a set of springs in my basement that will go on the car once I get another car.
I won't be able to drive it in the winter with it lowered. __________________ ...steven
