I will be doing my rear end right after I get my car running. Its will be Whipple 3.4 proefi128 tuned on e98 hoping for over 800hp. But I have a magnum t56 and 28" tall tires. I was thinking with 3.55 gears but need opinions. Car mostly gonna be drag and some street. Oncekin a blue moon I will drive like two hours away
