How does the amount of torque required to slip the clutches relate to % lockup? Or rephrased, how much torque should it take to slip the clutches on a stock M3 LSD (25% lockup?)? Is there a good way to ballpark this measurement using a torque wrench on the wheel bearing nut perhaps? Once again, thanks.

Yep, and the hood (bonnet) release on the passenger side. Mirror image of the BMW. Must be the UK heritage of the MINI (RHD driver gets to conveniently open the hood and gas (petrol) up at the side of the road), or just some limey's idea of a good joke. IIRC my TR4 had the bonnet release on the right side under the dash, and a central petrol filler. Then again it also had a buncha weird fastener sizes (Whitworth). And the factory repair manual talked about nearside and offside when discussing L/R. Kinda like port and starboard. vive la difference (sp?)

In a typical autocross day, one gets about 10-15 minutes max of run time. On a typical track day, one gets about 120 minutes at 30 minute each sessions. My experience with these tires have been not as negative as others but I think that the Ecsta V700s lack the grip that the Victoracers had. When I drive off the track and check the tire temps, I see around 180 degrees on all four corners with hot pressures approaching 36-38 range. This is on an E30 m3 race car. I did see some premature wear, but nothing too drastic in my use for one weekend and towards the end of the weekend the wear had stabilized.

There is a relationship but not a direct one. There should be specs for breakaway torque. Something in the 50 to 75 ft-lb range. While briskly accelerating from a stop while turning you should feel and hear the inside rear tire chirping as the limited slip locks and overspeeds the inside tire. This is like listening to your engine fan to determine if the fan clutch works. Paying attention to these things while driving makes it easy to keep tabs on your car.

It does seem that my M5 suffers more from the heat than have other cars I've owned, and given that I live in Houston, this modifation has certainly piqued my interest. My understanding is that the stock intake air temp sensor is integrated with the driver's side MAF. Anyone have any thoughts about this product? Would it be safe, and can anyone think of a downside?

Last night I noticed that our "new" '91 325iA is slightly lower on the left. I'm not about to panic. Also, I assume that UK cars are built the opposite way, or else they'll always look like they're about to tip over on a crowned road.
