At any rate, if I analyze the launch on this car, it shows a best launch of a clutch dump at approx 1900 rpms? I wonder if were not using different version of the program? Mine is version 4.5. >If your clutch is slipping then it's probably not >worth the extra wear just to get a number. Unless >you're planning on upgrading to a stronger clutch soon >anyway. Well, I really dont think the clutch is in jeopardy, at 18K miles of usually relatively mild driving. And if testing on a hill, and going to 4th or 5th at a lugging speed, I cant get a hint of slip no matter how hard I try. And, I have no trouble spinning the tires in first, or in second with a normal 1-2 shift at above 4K rpms and a quick letout...The only time it slips if if I'm in first at 6K rpms and powershift hard into second...When I let out the clutch, instead of a quick engagement, it just wants to slip to red line. But the fact that it produces a good 0-60 time probably means while it feels like its slipping, in that no quick takeup is evident, may not be...Again, no other method even gives a hint at slippage. Oh well.....When I finally do need a new clutch, maybe I'll try the Sachs Sport clutch. I believe its supposed to be heavy duty, and proably better able to handle the better than 300 crank hp I'm developing.

#2. G-Force, Crap or Crown Jewels? - from Jim Powell

Date: Mon, 11 Sep 2000 19:58:07 -0700 From: Jim Powell <jsp98m3@home.com> Subject: G-Force, Crap or Crown Jewels? In this corner we have Gentilozzi or whatever his name is, developing them on Trans Am. ***That might tell you something right there.*** And in our own little corner of the world we had Michael Lord, a very competent driver who dropped lots of money on lots of sets trying to get them figured out. Without success. Tires are like women. Nobody can agree on which one is the best. But it certainly does seem that the G-Force needs something beyond the norm to perform well. Never heard that about the originals. Set the pressure right to avoid the Groove of Doom and they were pretty forgiving. Unless BFG's exclusive target was Trans Am, it seems like they didn't quite come up with the perfect replacement. Jim

OK, I agree with you here. Definitely NOT a tire I would recommend to someone who doesn't have a lot of experience with driving schools. I can understand why instructors might be weary too. I have yet to look into instructing. At this point I am only 20, so walking up to someone and telling them I will be teaching them to drive probably wouldn't set too well. <g> Plus, I'm not so sure I want to get in a car with a student in the first place...I have a LOT of respect for those of you who do. You should see how nervous an instructor who doesn't know me is the first time he gets in the car! <g> I can see why a 20 year old in a race car might be a little scary! \> i DO think that if you spend the time (many months) getting used to g-forces > (meaning set up, like pressures, camber, etc and ALSO learning hhow to drive > them (it's not like every other tire)) then they probably DO perform the > best. at least that's what i've heard. I still don't know how to drive them to their limits, but I am to the point where I can get as much out of them as I did my Hoosiers. I'll explain a little further down why I stick with the BFG's even if they are harder to drive... > your chance of liking any non g-force tire mentioned here is about 99%. > they all rule (compared to street tires). based on the 20 people i know > who have tried g-forces, i'd put your chance of liking g-forces at 5%. that > seems like a pretty big risk to take, spending $800 for a set of tires that > you may hate. Here's the reason...did I mention that I can get a set for $350-$400?? <g> I don't care if they were to wear twice a quick as Hoosiers, I'd still come out on top. > that's never driven anything but street tires, i think you're taking a BIG > chance. both financially (since you may hate them and change to something > else) and physically (since you may total your M3 because they are so > "unfriendly"). Excellent advice...that's why my track car is a wrecked, salvage title 325 and the M3 won't be seeing the track anytime in the near future. Funny story, the car was wrecked in the front and the back, yet when my mechanic started aligning it, he found it to be straighter than the average car from factory. -Bryan Watts

I use BMW rims with a 41 mm offset. I think if you use rims with 41 mm or less offset, you won't have any problems up front. But too little offset and you might get rubbing on the rear fender. I would not recommend using 245/45 tires. They are much taller than the original tires. 245/45 tires are 25.7 inches vs. 245/40 tires which are 24.7 inches tall. That is 1.0 inch taller! That is a lot. You will notice a definite decrease in acceleration. Lowell Seaton '95 M3/2 - currently running 235/45-17 Toyo R-compound tires all around Dallas, Texas

I used to think that the outside mirrors are ALWAYS heated, regardless of the outside temperature. Yep, that's right. Even if it is 100 degrees outside, your mirrors are still heated. However, now I don't know what to think. It has been 100+ for so long in Dallas, I can't tell what is heated or not. And the last time I touched the mirrors when it was below freezing, I did not think the mirrors were heated. I figured something was burned out and my heated mirrors are kaput. Maybe you guys replacing your mirrors have miraculously fixed the heating element? Jiggled a wire so it makes contact again? Are you sure your mirrors weren't heating up before changing the glass?
