Welcome to the world of race car developement. No two cars are the same. No two combinations of engine parts are the same ( they can get close ). No two drivetrains are the same.

You now own a rather large experiment with four tires. Get a good set of tools and a lot of time and you can try various things to see what works best in your car.

Or, you can live with what you have and worry about the price of gas.

Hey, it's just a thought.
