I was thinking, I am planing on installing a JDM 4.7 final drive, keep in mind this is for drag racing
My wheels that I am running are 15'' tires are BFgoodrich Drag radials with a 23'' diameter and I droped my trap speed to 97mph from my 17'' rims with a tire diameter or 23.5'' and trap of 99mph. Smaller tire slower mph but faster acceleration. (then agian the mph drop my becuase of less tire spin)
Now if I go with a 4.7 final drive I will accl faster but chances are that my trap time will go down ago, my concern is when will my mph start to hurt my E.T. Do I have to worry about it with the 4.7 or is this more of a concern with the ATS 4.9 final drive.
