I bet it would respond to more gear. Shorter tire is the easiest way to experiment with that.
I have a 275 Hoosier radial on it. Don't know if they make anything shorter, and if they did it would probably look weird on the car.... Lol and for the 400 bucks I could be close money wise to doing the gear swap to a 4.30. The tires on it are shot, got two complete years on them.
At the end of the day it's primarily a streetcar, so trying not to lose that part of it to go faster, which is a fine line.
I was wondering if the extra gear would help it 60 foot better and get in its power band quicker?
