BTW, I am still trying to figure out if I want to go back to 3.64 or 3.38- with the 3.38s do you hit 5th gear at the Glen at all or are you able to keep it in 4th on straits? I have been playing around with a gear ratio calculator and am trying to figure out what will be the best compromise for a car that sees 20,000 miles a year and a hald dozen auto crosses and hopefully 4 track weekends.
We're gonna stick with the N52 for now. Later on, possibly an S65.
3.38 were perfect for Watkins Glen. 3rd & 4th gear only. I ended up running a 2:24 in the dry on R-comps.
