im really confused in wat type of gears i should get for my 06 gt??? i heard 373's dont do enough but are really good if its for everyday driving. and 4.10's are awsome but not to sure bout every day driving? i drive my car every day and i need a gear thats gonna give me the best performance but also to where i can drive my car every day with out a problem. also, is there anything i should do to my rear end or anything that might break to "not" break?? i use micky t"s at the track.
