Having had two head gaskets blow due to overheating due to a t-stat stuck closed, I no longer go on track until I've let the car warm up and I physically check that the upper radiator hose is plenty warm. A temp sender in the t-stat housing would let me do that from the cockpit. --Scott '95 M3 ------------------------- > Date: Mon, 4 Apr 2005 12:46:04 -0700 > From: "Andy Radin" <fourfa@hotmail.com> > Subject: Re: [E36M3] Re: Water temp sender location > > "I tapped my Alum housing 2 years ago. works great. and is a very > easy to > do." > > Same here, I did this to mine about three years ago.

#2. Ignition coil problem - from Robert Exconde - 99e36m2

I called the dealer and he told me to replace all 6 including the boot. He told me that bad ignitnion wires can damage the DME.... Is this true? at $82 a coil, its not cheap.

The boot is part of the coil pack, AFAIK. > He > told me that bad ignitnion wires can damage the DME.... Is this true? True. I also had been instructed to replace all 6 when I was troubleshooting an issue with the race car. Also, be sure to use the same brand of coil packs as the originals. I'm not sure if this is an issue on the M3, but on the 325is there were 2 brands available, Bosch and Bremi. > at > $82 > a coil, its not cheap. True, but compare that to $1300-$1500 for a DME... Hope that helps, Jim Bassett 1998 M3/4 - original coil packs 1993 325is #44 JP - new coils packs (they weren't they problem, however :-))

#4. R compounds advice - from Carl Stern

Date: Tue, 05 Apr 2005 14:57:14 -0600 From: Carl Stern <carl.stern@xilinx.com> Subject: R compounds advice Time to get some new R compounds for DE schools and track days. I'm looking to move up to something better (stickier) than the Yokohama A032Rs I have been using. I finally feel that the tire is now limiting me more than the driver is. I'm thinking of switching to the Toyo RA1. I still would prefer to be able to drive to the track on them, and have them last more than a weekend. So I am willing to tradeoff some ultimate grip for some longevity. Any better choice than this for what I want? What air pressures do folks like with this tire? Am I correct in thinking that the other options, Hoosier, Kumho, Cup Sports, etc. will have better grip at the expense of wear? What else is out there? I have made it up to the A group in our club school (RMCBMWCCA). I run a stock 95, except for a full Conforti intake setup. I have new Konis going on, but springs, sways, bushings, alignment, etc. remain stock and likely will stay that way. The car is still a daily driver. The only other thing I do for track days is put on PF 97 pads in front with ATE super blue. How much would I notice moving up from 7.5" wheels to 8.5"? I've been using 235/40-17s. With my 95 diff gearing and high altitude, I don't really want to raise my gear ratio by the bigger tires. A little more width wouldn't hurt though. How much will an X brace do? What does it weigh? thanks, Carl 95 M3 39k Daytona Violet

No. The Toyos are what you want IMO. BTDT. Still do, actually, as RA-1s are my "street" tire on the race, which I drive to/from the track. I also use them for non-race events, like instructing, etc. > What air pressures do folks like with this tire? IIRC, I'd start out high-20s, low-30s cold, and adjust from there. > Am I correct in thinking that the other options, Hoosier, > Kumho, Cup Sports, etc. will have better grip at the expense of > wear?

Gosh, that sounds awfully familiar :-) Change the Koni's back to stock and go with UUC swaybars and you have fully described the '98 M3/4 during it's time as my driver's school car :-) > How much would I notice moving up from 7.5" wheels to 8.5"? That would be a noticeable increase in grip, I would think. FWIW, I ran 235/40/17 RA-1s on 8" wheels on the M3. They were perfectly fine for that job. > How much will an X brace do? I felt it made a difference in terms of turn-in/steering response. Plus, it does a nice job protecting the oil pan :-) > What does it weigh? Dunno. Does it matter?

Very good grip, consistant through it's useable life (which is up until you see cords for the most part), very predictable and and absolutely incredible longevity for what you might put it through. << Any better choice than this for what I want? >> I don't think so. I'm using the Pirelli Corsas currently because they were very inexpensive and allowed me to order my new track wheels with tires on them rather than dealing with ordering seperately and getting them mounted. They're good, especially for the price, but I think the Toyo edges them out on most fronts. Lateral grip seems better right now, but that could simply be because I moved from 235s to 255s. << What air pressures do folks like with this tire? >> Depending on ambient temps, I'd usually start in the low-30s. Once HOT, I make sure to keep them under 40psi (HOT). << The only other thing I do for track days is put on PF 97 pads >> You'll notice a nice increase in braking performance with the combination of Rs and those pads. << I've been using 235/40-17s. With my 95 diff gearing and high altitude, I don't really want to raise my gear ratio by the bigger tires. >> If you go with the Toyos you'll have the choice of 235/40 or 255/40. For now, you might as well go with the 235s, since you know they'll fit with no problems. The increase in grip will still be very noticeable. << How much will an X brace do? What does it weigh? It made my steering feel a bit more direct (that initial steering input anway). As for weight, I have no idea, but I think the benefits of steering feel and protection of my oil pan (lord knows I've hit enough things with the brace) were worth it. Jonathan L.
