Date: Tue, 1 Apr 2003 21:28:05 -0500 From: "Jeremy Lucas" <jlucas@columbus.rr.com> Subject: Re: [E36M3] RE: Track Tire Question I thought I would add a comment to help avoid future confusion. Both the older VictoRacer's and the new race compound Ecsta are called V700, so be sure to be more specific when you are ordering by phone. As mentioned, the Ecsta V700s are their sticker, larger tread blocked, race compound tire; although the rubber compounding on the old Victoracer carcass was updated last year too. The Ecsta V700s are also significantly lighter than the same size VictoRacer V700 tire but the VictoRacer is much more durable. 2 weekends ago, I wore out a set of Ecsta V700 about 3 laps before the end of a 1.5 hour enduro at VIR (in a Honda Prelude), where after a 3 hour enduro on VictoRacers they still life in them. Looking at the tires in impound after the race another driver who has 97 M3 track day car told me he also wore out a set of the Ecstas in one weekend at a BMWCCA driver ed event. YMMV, but for a driver's ed tire I'd avoid the Ecsta V700. They are faster but unless your racing it's not worth it. Also for dry weather racing both are recommend to be shaved (yes, even the Ecsta). I'd recommend Vilven Tire for your track tire needs (888-775-8646). They have excellent service (for example, they run Kumho's race support program). When I checked last fall 235/40/17 Toyo Proxes RA1 were $170 each from Vilven.

#2. Terminology: Shocks....stiffness - from Chester Wong
Top
Date: Tue, 1 Apr 2003 18:44:09 -0800 (PST) From: Chester Wong <chester_p_wong@yahoo.com> Subject: Terminology: Shocks....stiffness I just want to make sure that what I am thinking is conveyed when I'm speaking valving about shocks. With Koni SA and DA shocks, you can adjust the shock to "stiffer" or "softer". My question is: what do you mean when you talk about setting the shock to full stiff or full soft? To me, when I talk about setting a shock to full stiff, I'm talking about setting the shock where rebound is the slowest (it takes the shock longer to return to full length). This made sense to me as I would set the shock to full stiff for a stiffer spring. Now I'm hearing the opposite where shocks set to full stiff have minimal rebound dampening so that the tire is "always on the road". Comments? TIA, Chester =====

#6. (follow up) Radiator about to go? Also, water pump Q - from K Quistorff
Top
Date: Tue, 1 Apr 2003 22:23:37 -0500 From: "K Quistorff" <kqkq@nc.rr.com> Subject: (follow up) Radiator about to go? Also, water pump Q In regards to my post yesterday about my radiator leaking coolant, upon closer inspection this evening, it turns out the coolant is actually leaking from the underside of the overflow hose, immediately above the upper radiator hose neck. (At first it appeared to be coming from the upper radiator hose neck itself, but that no longer appears to be the case.) Like other fluid leaks I've found on my M3, the culprit seems to be the crappy press fit hose clamp BMW chose to use on the overflow hose, replaced this evening with a real hose clamp. Even so, since my M3 has 72 kmi and some track time, I'm taking you guys' advice to replace the radiator before it fails at a most inopportune time - I ordered a new radiator, water pump, etc. from Bimmerparts this morning and should have it before my driver's ed at VIR on Monday. BTW, is there an easy way to confirm whether my existing water pump has the metal or plastic impeller? My M3 is a '96 model. If it came with the metal impeller pump, what is the recommended replacement interval? Just wondering if I should bother relacing the water pump now or if it's low enough risk to hold off awhile longer. I realize it would be a convenient time with the radiator out, but the radiator swap looks like a much quicker job than the water pump, and I don't have much time to work on the car right now.

Full stiff means it is harder to move the shock. If the shock is way underdamped, or way overdamped for the spring, the tire will not always be "on the road". Shocks need to be set to match the springs.

#10. RE: [E36M3] going to san marino GP -- advice? - from Murray Roblin

Date: Tue, 1 Apr 2003 21:00:00 -0800 From: "Murray Roblin" <murray@farleyroblin.com> Subject: RE: [E36M3] going to san marino GP -- advice? I've got no input on hotels in Bologna, but have traveled to Italy quite a bit, for both business and pleasure. Trains are fine for major city to major city; cars are a major hassle in the big cities as well. However, for travelling to small towns, visiting the countryside, cars are a much better option as they provide easy access to the interesting, small, out of the way places. In our last trip, about 18 months ago, we spent time in Rome and then Tuscany. Taxis in Rome, train between Rome and Florence, and then rented a car from National out of Florence. Our only problem occurred when we were doing a day trip from Florence and returned to the city after they closed down the streets - we just couldn't figure out how to get the car onto the street in front of the hotel. After about 10 tries, we gave up, parked it a few blocks away and had the garage guy come and get it. Driving in Italy is no problem, you just to be sure that you're committed to whatever move your going to make - announce your intentions and follow through. Enjoy your time there - Bolognese cuisine is supposed to be the best in Italy.
