There was a guy at the track last night with an '03 Sonic blue cobra.. he was running 9.75's in the 1000 ft.. he saw my car and came over and talked to me about what all i had done to it.. then he asked if i wanted to swap my solid rear for his independent rear.. it would be swapped from rotor to rotor, including all the brake lines, sensors, etc.. along w/the exhaust after the midpipe to the tips on both cars.. he said since he had enough $$, and it'd be costing him less to do this than it would be to buy another one and get it put in, he would pay for everything except for my gas up to the shop, which is about 1 1/2 hours away from my house via the interstate.. is it worth it to get the independent rear end or should i keep mine?
