I've currently got 4.10's with my A4, and yes, they scream out on the highway. So do 3.73's (I had them last year) but if you don't do a lot of highway driving, why not go all the way? However, 3.73's are probably a little nicer "all-around" street gear. The 4.10's are the best for the 1/4 mile though IMO.....you cross the line between 5500 - 6000 RPM, which is putting the LS1 right into its power band.

FWIW, I ran the same time with 3.73's as I did with 2.73's, and even lost 1 mph (although, I couldn't get traction either). This year with the 4.10's, I've shaved off .4 seconds, and picked up about ~1 mph.

 

4.10s it is

 

Try and order 4.11's actually.....I can't remember who makes them, but the gears are 37 & 9 teeth instead of 41 & 10, which makes them thicker, and theoretically stronger.

 

ok thanks man i will do a search
