12 bolt or 9"

Trust me, after doing my cam and weight reductions, a 12 bolt is next! Dont know how many days left the stocker has.

Don't know how many miles your car has but if its under 75k I'd go with a cam. It would would add good hp with your current exhaust set up. The stock rearend can take a lot of abuse. Good Luck, I wish I had $2000 to spend

If its an A4 id get a converter, if not, id go with the TR220 cam and you would still have some left over After that you could throw them macs away and get you a good set of LT's. Happy modding man.

9" with a 3.73 if an A4... probably the first and best mod you should do... then slicks next with the converter to follow.....

How about some nitrous and a walbro? Some ideas...A4 get a converter, M6 get a shifter or clutch. Pacesetters are a good bang for the buck, How bout an LS6 intake. The rear end isn't a bad idea depending on how much you race the car.

He's got it exactly.

It depends alittle bit on how you want the car to behave, how much you actually race it, etc.

12 bolt and some nitrous would be my vote .... cam / ls6 intake would definately help you out alot ... and a converter/clutch & shifter would be a nice difference too. Like I said though, it really depends on what you plan on using the car for.
