We have just recently joined the ranks of 987 owners with a 2007 in Arctic Silver, and have been enjoying it immensely as a daily driver soon to be at sea level in CA. What would you suggest for making it even more fun ?
If you wanted to have a "performance" improvement, you should fill with Helium. It has great thermal conductivity, would reduce unsprung weight and of course would cost even more for that enhanced snob appeal. Especially if you buy Semiconductor Grade or 6-9's purity. regards, Salty (A practicing engineer, one day maybe I'll get it right)
