Plus you get to drive a track that is frequented by the Sprint Cup boys. I just hate going straight for too long (which is why I like Mid Ohio). I can fly out to Utah or TX and drive straight and fast all day. If you really want scenery on a track, get up to Tremblant (St. Jovite) north of Montreal. The track also has some elevation changes that are a blast (at least they were pre-renovation). The town/resort also has great food and other things for your family to do while you're there...golf, lake biking, etc) they also have a great set of festivals in the summer, and you can dovetail a school with the Montreal GP if you time things right. Now THERE's presence.

The Bentley manual is not at all helpful on this subject. By "hangs up" I mean when lowering the top, the metal "lid" section doesn't get up far enough for the window section to get past it on it's way into the "trunk", and it becomes stuck, so that I have to get out and push the lid back a few inches before I continue lowering the top. Looking at the mechanism, it appears to be the fault of the round "actuator" lever, one end of which rides on a rotating notched cam arrangement. The lever has a length adjustment, but I have adjusted it all the way and it still isn't "long" enough. Anybody have this problem? Anyone fix it themselves?

#6. [E36M3] Hard to Start - from William T
Top
Date: Wed, 26 Mar 2008 20:53:54 -0400 From: "William T" <emailmeman@embarqmail.com> Subject: [E36M3] Hard to Start Okay, so I have been chasing a hard to start issue for a while. To summarize: The car is hard to start after sitting for a while (5 to 10 minutes). It will take 5 - 8 seconds of cranking just to get it started back again. So I had come to the conclusion that there is a leak somewhere in the fuel system that's allowing it to de-pressurize while sitting. So, last week I got serious about troubleshooting. I break out the Bentley and run a few tests. The car does run so the FPR test was an obvious answer, but I ran it anyway. However, I decided to check and see if I was getting a priming pulse when I turn the ignition switch to the on position. The answer is NO, a multimeter verifies that I am not getting any voltage to the black terminal on the Fuel Pump assembly until the key is in the start position. So, should I be getting a priming pulse when the ignition switch is moved to the run position? Also, I have not smelled or seen any fuel all during the time I have had this little nagging issue. But, the fuel system has to be losing pressure somewhere? Thanks in advance. W. Wallace BMWCCA TSCC

One of your injectors may be leaking, its also possible for the system to lose pressure at the pump itself allowing the fuel to flow back into the tank. The 1st thing I would do is let the car sit for 30m after running and then see if the fuel rail still has pressure. If not, I would check the injectors for leaks...might just be easiest to borrow a known good set for testing...I think I have a set laying around... Dave

The buton on the new switch seems to move the right way when I depress the pedal Any ideas?

Very lite, and fairly strong. I have several of them in my garage.. On tire size for this car, I have always felt the 245 40 17 was the perfect size.. (grip Vs. weight - for a car making around stockish HP). Now with your extra power, you may find that you may need larger rear tires.. Have you thought about the Falken FK452? I just bought a set in 2454017 for my M3 street car, and so far I like them...

I thought I would share my decision-making with the group in case I am way off base. Right now I have Kumho Ecsta ASX all seasons on the car that I use for winter (not much snow in my area, but cold enough that summer tires are out of the question). Previously I had conti sport contact 2's that were on the car when I bought it, but they reached the end of their useful life last year. After reading all the posts, much research, and hours reviewing data on Tire-Rack, I finally decided (unless somebody talks me out of it) on Michillen Pilot Sport PS2's mounted on Kosei K-1's in size 235/40/17 at all four corners. One of my goals was to reduce the unsprung weight of the car as much as possible, in addition to having a decent tire for daily driving and that I could use for HPDE. The PS 2's, in addition to being a good tire overall, are about 5-6 lbs lighter than most of the extreme high performance tires in similar size. That combined with the Kosei's saves me at least ten pounds of unsprung weight per wheel compared to a stock wheel and extreme perf. tire, which seems like a pretty good benefit. I have already removed a ton of weight off the car, and like the idea of complementing that with reducing the unsprung weight as well. In addition to some better acceleration, maybe it will yield some modest gains in fuel economy so I can say I am doing my part to save the planet. I originally wanted to score some of the discontinued Dunlop Direzza Sport Z1's (now replaced by star spec) because they were cheap, but they only have then in 245/45 apect ratio as far as I can tell (no 40's), and the 45 is a taller tire than I am comfortable with. The 45 is the same diameter as an 18 inch 40 aspect ratio, and with a lowered suspension, I'd rather not do it. They also weigh close to 5 lbs per tire more than the PS2. I also considered the PS2's in a wider size, but I can save $20 per tire by sticking with the 235's rather than going up to the 245's. I believe 235's were OEM for the 95 car. My car is supercharged, so it does make a lot of power. It's also probably 250 lbs lighter than stock and getting lighter, and with a lower center of gravity thanks to removal of the sunroof assembly. So, I am thinking that since it is not a hard core track car, I can get away with the 235's in the PS2 tire matched to the inexpensive Kosei's, not bust my budget any more than necessary, and have the advantage of a nice reduction in unsprung weight. Any comments or feedback appreciated. I appreciate all I have learned from this list. Matt Bader 98 M3/4 Delaware

Its been about 10 yrs since I changed the fluid so I tried doing research. On the Red Line website, they have both MTL and ATF. IIRC, I used ATF back then. What should I use now? Should I stick with Red Line or should I go with Royal Purple or Amsoil(or something else I don't know)? Thanks.
