Well, I'll give you my 2 cents. I look at it from a couple of points of view: - You should at least be a 'B' group student. - You're planning on doing more than a couple of schools a year. - Consider wear & tear on the street tires vs. cost of 2nd set of wheels & tires. When I switched to R-compounds (Toyo RA-1) I was a 'B' student, was embarking on a year where I ran ~20 events, and I had just replaced the OE tires on the M3. So I was looking to "save" the new set of street tires based on the number of events I was planning on running (I wouldn't have gotten 40,000 miles out of the Pilot Sports otherwise :-)). Even at the rate I was doing track events, the Toyos were lasting nearly a whole year (full tread), so it worked out from a budget standpoint. YMMV :-) That's just one data point. If you know John Mathew (LA-area M3 driver), he ran on street tires well into the 'A' group, is a VERY good driver, and was nearly as quick as I was on the Toyos. So there's another data point. Hope that helps, Jim Bassett 1998 M3/4 1993 325is #44 KP

After reading it, it looks like the author is saying to leave the V1 phone/power wire exposed and to run it over to the V1. A cleaner way to do it would be to run the wire up into the headliner and over to where the V1 will be. Then pull the wire out from between the headliner and windshield in that position. If the V1 is mounted high enough up on the windshield, only 1-2 inches of wire needs to be exposed. Just my $.02 Rob -----Original Message----- http://www.bmw-m.net/TechProc/v1.htm Scott, I just followed the procedure here and installed it in my 98. Pretty easy. Instead of using wire taps I just connected to the hot wire using the V1's direct power wire tap and connect the ground to one of the screws in the sunroof assembly. -Johnny

#7. V1 display mounted in rear view mirror - from Robert S. Hatrak II

Date: Fri, 22 Mar 2002 10:43:12 -0800 From: "Robert S. Hatrak II" <hatrak@ix.netcom.com> Subject: V1 display mounted in rear view mirror In case anyone is curious, I installed the mirror that Jim Powell modified for me that has a built in V1 display. I first mounted it temporarily in the M3 (that's why wire can be seen, etc.), and then gave it to my sister and installed it in her E46 when I decided that mounting a V1 in the rear window wasn't for me.

This is assuming there is zero drag. There is a LOT of drag. First, aerodynamic (less significant).. but the car goes thru the air better forwards than sideways (we're talking 60mph or so, right?). The bigger force is the drag of the rear wheels on the ground. There is no reason for them to come around unless they are going faster than the fronts. If your fronts are spinning at road speed, your rears are being "pulled" backwards by the road going by underneath the car. I suppose if you kept your foot on the gas and braked the front wheels, you'd spin, sure.. - reid

Heh. Although we're talking highway driving, this EXACT thing happened to a very good driver this weekend at Sears Point. Heading down the straight between Turns 6 & 7 on Sun AM - raining and lots of standing water. Said driver was off-line as he was passing me in the straight. I get to the braking zone, and he's no longer next to me. Check the mirror, nope, didn't tuck back in behind me. Next lap I see - he had spun off into the hillside. He was going staight, hit puddles and hydroplaned, then one wheel found pavement with grip & spun the car. Nothing he could do. Jim Bassett
