My buddy just gutted the whole rear section of his 2006 type S. He dropped 3/10's of a second, same exact setup minus some weight. Same 60's as before, just lower ET and 3-4mph faster.. He has I/H/E, and K-pro reflash. Went from consistant 14.5's to consistant 14.2's.

There is my PROOF that weight reduction does help. Im willing to bet most ppl here that say it doesnt make a difference have never done it...

The saying is every 100lbs of weight taken out is 1/10th of a second. Im not saying he took out 300lbs, or anywhere close, but he did have Major results.
