OK, 'nother dumb question.
How do I change the rear axle ratio in my C425 Javelin? When I go into Tune Setup or whatever it's called and go where the transmission and rear gear ratios are I can't change any of them. Do I need to upgrade them?
I kicked arse with the Javelin through all the C-level races but can't get first in the last Trans Am oval race because I only top out at 129.
