Alright I just got me 03 Mach1 5 spd. I was just wanted to know a few, "basics". Gear ratio?, Whats the widest tire I can put on the rear on the mach1 rims? Do they come with a performance shifter? Mine has one and I love it! I know I have alot more questions I just can't remember right now! I also know I can search the net and find these answers but thats pretty time consuming so I figured I would ask my Mach1 hombres. Drop some knowledge on me.
