Let's put the toothpaste back in the tube...

How will running no rear bar and a huge front bar help with rotation?

I'll take all the steak you'll feed me...


... But it's not gonna do anything to diminish the advantage I have! HAH!

We need to feed that boy some Texas steak!

I think I weighed that much..... when I was a fetus!

I went faster on Dunlops vs. the Bridgestones I was on that day.



I have to say, the car felt good! I think my natural weight advantage made the difference!

OUCH! Oh, you bastard!



I'm gonna get Redwood to ride with you!

Even though you went faster at 35f/30r ?

Re: 97 M3/4/5 running in STU

We run more camber and more rear spring. 1/4" toe-in in the rear makes a difference as well.

They're yours with -3.5 front, -2 rear

Re: 97 M3/4/5 running in STU

And I see "TCK coilovers" but no reference to camber plates. Gotta have camber on BMWs.

Re: 97 M3/4/5 running in STU

We still have the stock sway bars on the 97 M3. Want to get through three rounds of Slush series before any more changes are made to the setup. Just concentrating on tire pressures, shocks and alignment.

Re: 97 M3/4/5 running in STU

I run 640F/720R spring rates, 28mm H&R front bar on full stiff, no rear bar. At 35F/35R, the car didn't rotate enough, and dropping the rears to 33 seemed to do the trick.

I am looking into fabricating a bigger front bar (speedway nascar style), as I love the adjustability of them, being able to swap cores. We have them on our AS S2000 and my STS Civic.

Re: 97 M3/4/5 running in STU

I've found 34psi to be the happy spot for the Dunlops (with adequate negative camber).

Even though you went faster at 35f/30r ?

255s are a big step up from the 245s, especially on a 9"+ wheel. The grip difference is immediate and very apparent.

And how! Not to mention they work great 30 minutes at a time at Pueblo

RE: Car still pushes

-What front swaybar? What setting?

[BrianGT]

Re: 97 M3/4/5 running in STU

I played around a bit with pressures, and settled with 35F / 33R for the Dunlop StarSpec pressures.
