spedrcr,

Good question about the temperature drop. I did some measurements, but they were of the shock absorber, the tire rim and the tire sidewall, because that is what I was most concerned about reducing heat transfer to.

In general, these temperatures went down 35 - 85°F, depending on how long I drove the car and where I made the measurements.

I also found that the more complete the wrap, the better.

Fyi, the measurements were made with a low-cost optical pyrometer that has quite a bit of variation in spot size with distance because of the difficulty in mounting thermocouples to the surfaces for more accurate readings, so area averaging may be reducing the actual temperature drop. Of course, "your results may vary" as they say...

I'm happy to hear that the DEI turbo blanket made a nice difference. I've always been uncomfortable how hot the rear bumper gets, so I'll certainly consider that for my 911.
