I'm thinking of going to an A4 because I can get a good deal on a TH400. My first question has to do with gear ratio/converter combos. Check sig for mods. I run 28" ET streets and w/ my m6 I shifted at 6600-6700. I am not concerned with daily driveablity. Would a 4200-4400 stall be to much with my 4.30 gear and 28's? If so what would be recommended? Also should I go with a brake and keep the 2-step I already have? Last question is this worth doing. My car has cut the best 60ft of 1.58 with stock spings, sway bar, no airbag. If I upgraded these the 60ft and ET would definatley improve. Guess my question is should I swap or just keep the M6 and try to improve the times? Also if I went ahead and did the swap how much would I gain? Thanks for the help! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
