I have an 04 mach 1, with cat back, lowering springs, staggered wheel combo, sub frame connectors, shocks struts etc.. Basically I'm working on making this more of a track car and i was wondering which gears would be best.
I had 3.73s in my GT and loved them, but for my mach I'm thinking of either 4.10 or 4.30s. Any opinions? and i put my 3.73s in last time, but id rather just take it to a shop this time. If i have the gears, what shop near pittsburgh would be best to take it to? (on a budget)
