We've tigged a diff to create a locker, Mid ohio teener club thanks, but what gears and where can i buy them. thanks for any thoughts and recommendations Here is a previous thread with some good info on regearing a 901: http://www.914world.com/bbs2/index.php?act...=45&t=60883 In that thread I posted an excel spreadsheet that you might want to look at. You can do all sorts of "what if" gear combos. I have two gearboxes right now: A-F-Ka-Q-V and A-F-M-S-X The 1st box is getting a Ga second gear as my next improvement... I got my gears at High Performance House 650 364-6234 Ask for Rich, he can help you select the right gear combos for your car/track. |
