What gearing is in your car? You'll want the 20/55 if you plan to run pretty much any decent motor or get the adjustable gearing parts. The final gear ratio with this combo is 7.15:1 which is pretty good with a Monster stock motor, 19T or as low as a 17T motor. I really wouldn't go with anything hotter than that due to the fact that you will be overgeared and cooling is a big problem with the car under the best of circumstances.
