check out post #116 in the thread. i don't have the know-how to challenge this, but he seems pretty confident.

Final drive ratio of our diff is 3.85:1
So Tires will be rotating at 1200/3.85 = 3117rpm
OME rear wheel and tire circumference is 83inches
3117 x 83 inches/min = speech of car at that rotation
converting to miles per hr is = 240 mph
so minimal vibration at 240mph, but I'm not sure how "minimal" it will be for you or me

also, towards the end of the thread, there is more discussion about his from a gentlemen that seems to have a pretty good feel for his car, and reports testing it at 140 mph.

I attributed this to it probably being better balanced. Also, I have had the car to 140mph already, and noticed no real increase in NVH from before. Keep in mind, I have the stock 1M/M3 subframe mounts in the car.....Hope this helps.
