I personally would not do a HPDE on different tires f/r. I was in a similar situation recently and had two different brands on the car for a short time. No schools, but I did do an autocross just for fun on this setup. Let me tell you, you really don't notice the difference between tire performance until you have two different sets on the car. In my case, the rears wee not as sticky as the fronts which led to some fun, but unacceptable, handling qualities. My car normally understeers with street tires and it was as tail happy as could be with the mixed set. At the track it would have been a disaster. OK, so let's say you assume your new tires are the better tire and being smarter than I am, you put the sticker set out back. In that case, you're likely to experience understeer... frustrating at the track, but we're OK with that. However, does that rear set grip better in all conditions? What if it rains? Cold temps? What about transitions as well as steady state cornering? Which tire gets greasy with heat first? What about braking balance? There are way too many variables and you could end up with a very ill handling car. At best, you'll be wondering why your car doesn't feel right all day, at worst... well, use your imagination. -- Ron Katona

#2. Observation on chassis stiffness - from The Abels

Date: Sat, 12 Jan 2002 11:20:59 -0600 From: "The Abels" <aAbel@austin.rr.com> Subject: Observation on chassis stiffness Just thought I'd pass this along as I thought it noteworthy. My 97 M3/4 (non-fold down rear seats) went from stock trim to X-brace, UUC Strut Barbarian, AA rear brace, H&R c/o's. In so doing, I can now jack up my car from one jackpoint (either front or rear hockey puck) and raise the entire side of the car. Not sure if it's due to the bracing, the c/o's or both. But, I think it's pretty cool, as it makes changing wheels a bit easier. Cheers, Jeff 97 M3/4, stiffened

I am looking for a mechanic in the Sunnyvale/Cupertino area (within 15miles or somethn would be nice). Additionally a pointer to the E46M3 RSM install and parts list would be apreciated as would a recommendation on a place to purchase those parts. Thanks, Eric

Date: Sat, 12 Jan 2002 12:13:37 -0600 From: "The Abels" <aAbel@austin.rr.com> Subject: Re: [E36M3] Observation on chassis stiffness Matt, With the travel of the suspension stock, and the max height of my floor jack, the jack would max-out before the other wheel would leave the ground. Now, in a few pumps of the jack, both leave the ground. Perhaps it's all due to the reduced travel and stiffness of the aftermarket suspension. The car is dropped 1" at each corner.

It's probably the coil overs since the springs don't determine the fully extended height. I have biltstein shocks/struts, which must also have a shorter extension than the stockers. -Matt --- The Abels <aAbel@austin.rr.com> wrote: > Date: Sat, 12 Jan 2002 12:13:37 -0600 > From: "The Abels" <aAbel@austin.rr.com> > Subject: Re: [E36M3] Observation on chassis > stiffness > > Matt, > > With the travel of the suspension stock, and the max > height of my floor > jack, the jack would max-out before the other wheel > would leave the ground. > Now, in a few pumps of the jack, both leave the > ground. > > Perhaps it's all due to the reduced travel and > stiffness of the aftermarket > suspension.

Date: Sat, 12 Jan 2002 16:14:44 -0500 From: "Carey Probst" <hcprobst@alum.mit.edu> Subject: RE: [E36M3] Observation on chassis stiffness I have the X-brace and front and rear strut braces on stock suspension. I discovered that using Steve D's jack plate, I can easily lift both tires off the ground when using the rear jack point but not when using the front point. I would have thought the other given engine weight in the front. Noticed this effect earlier this year when putting on the winter tires. Seems strange to me.

#8. Tires a rubbin' - Ideas? - from Chris Teague
Top
Date: Sat, 12 Jan 2002 16:17:49 -0800 From: "Chris Teague" <cteague@home.com> Subject: Tires a rubbin' - Ideas? I just put on H&R sport springs, plus Eibach sway bars. Then I added a set of SSR Integral 17x9 wheels with 255/40-17 Kumho victoracers. I am getting a little rubbing on the outer rear fender toward the back. Very close to where the fender meets the bumper cover. Anyone think this will cause a serious problem for autox? Should I have the fenders rolled? I don't see any sign of it cutting the tire, just some slight rubbing when I hit a bump. The alignment specs in back are 1.9 degrees camber, and about 1/16" total toe in, on a 97 4-Door. Chris P.S. I had ordered the new 235/40 tires from tirerack, but since they were out of stock for a while, I went with these instead. I may try the 235's next time. Fronts clear fine.

You can try to get some clearence by adding camber if you want more anyway. 1.9" is probably about as much as most would want on a street car. The other option is to roll the fenders. Depending on how pretty your car is you can either pay someone to do it, use the Tire Rack roller or just get piece of wood like a baseball bat. I think I used a big 1" dowel-like piece of wood and raised the rear of the car until I could get it between the tire. I didn't damage the paint but YMMV.

You will not notice a chassis stiffening effect until you do a good weld in full cage. Lower X brace does have the most noticeable effect compared to the other braces, only one you can actually feel IMO. But any bracing is a good thing, especially in a off-road excursion, pot hole, etc. Mike ----- Original Message ----- From: "The Abels" <aAbel@austin.rr.com> > Just thought I'd pass this along as I thought it noteworthy.
