Ran the 24 hours of lemons car this past weekend. One of the changes we made was installing 3.55s instead of the 3.08s in the rear to keep from having to shift into 2nd coming out of the turns. That worked out great in terms of making the car quicker around the track, but what didn't work out so great about it was that with 3.55s and hitting 135mph on the straight, the stock driveshaft was not happy, and we ended up cracking 2 tailshaft housings, so if anyone has a dead M5R2 they can sell me the tailshaft housing off of, let me know how much shipped to 07724. We are also going to go to an aluminum driveshaft for the next race to hopefully solve this problem.
