its heavier. I think the only good thing about it "STOCK" was the sun and sound package with the rockford fosgate and the sub in the trunk. other than that it was too heavy, slow acceleration, corners i had to take slow, and I felt too high when sittin in it. About the SDS stage 3 though. My friend said the only difference between the Stage 2 and Stage 3 was upgraded pistons, programmed box, belt tensioner, and an aluminum pulley I guess. What do u think about this? I honestly want to be running 11 sec in the quarter mile like MATT was with his black SDS stage 3. But i'm sure somehow it's possible with the TC.
