i have a 98 gt just got long tube headers,off road h pipe, flowmasters, cai, steeda pullies, 70mm tb, short shifter, dropped 2 in and with new 275 tires in the back. what should i be running?
do you have an auto? if not, and you aren't planning on a power adder, get 4.10's. if you are planning on a poweradder and have a 5 speed, get 3.73's. 3.55's really won't do much for you.
