Just put in a 9" diff with 3.70 gears! I'm pretty excited about seeing what i can do at the track... what do you guys think I'll run with this setup?

SLP Lid, Kooks LT's, Magnaflow 3" Exhaust with no cats, complete suspension work, and a set of Mickey Thompsons ET Streets.

I dynoed 323whp without the headers so with a tune i should be around 340-350whp.....

Think i can break 12.5?

 

Does ye hath have an auto?

 

6-speed

 

in good air and good prep on stickies yeah I dont see why not....

 

If you launch good you should be mid to low 12. My car has never been dyno'd but im about the same as you mod wise, im full bolt on, m6 4.10, but im still on the 10 bolt. Im going to the track and shooting for low 12's. Im on Mt et street 26x11.5x17. I have seen full weight reduction A4 with a stall and bolt ons run 12.1's.. Id be happy in m6 with 12.5.. If i run a 13 someone may be getting a good deal on a ta..

Congrats on the 9 inch, and it must be a good feeling knowing the rear end will not break, now you just have to worry about trans/motor..

Tell me about it Im super excited to break this thing in already.... all my rear suspension work is pretty much done also.... so now I can pretty much just do pure power mods and let it rip

I wish I would've gone with 4.10's...... if anyone is reading this and has a M6 and thinking about going 3.73 or so.... dont do it!!! Get 4.10!!!!
