I am considering getting a lightweight flywheel for my soon-to-be-repaired JC5 and Gripper diff. Also, I am considering having the final drive modified to give a lower ratio of gearing. I am in two minds however as normal daily driving will be more hectic and there are other negatives.
People with modified lower ratio boxes: Is it worth it?
I will have another car soonish and the Williams will be mainly fun and track days car.
