Hello....you need to swap a differential from a manual trans car....it has a 3.45 gearing, so it will solve your problem. At 60 mph, the engine rpm would probably be around 3400, so you can easily cruise at higher speeds. One was just sold on this website, so they come up occasionally. Or search other sites like ebay. There is a bmw parts shop near philadelphia called prussian motors...they have a website with their inventory and would likely have one. I think there are other shops in Virginia as well....should not be too difficult to track down. Good luck! |
