Default 4.56 A4

I'm about to order a spooled 12 bolt..

I run at high DA's, running 1 sec slower + than most of you here...

Right now with stock 3.23s and 26" tire I'm trapping at 105mph (12.82 / 8222DA )

I was thinking about going 4.56 with a 28" tire, that would leave me with a 113mph 3rd gear at 6200rpm according to a gear calculator.

Do this seems right? i won't add any big HP yet, still going for bolt ons and suspension first...

What do you guys think?

I'd think that you'd be better off going with a 4.10 gear and alot looser converter.

I hear that, I would have gone 4.56's with my 6sp if I didn't drive the car everyday. But I think it's too much gear with an A4 unless it's and all out drag car.

Sounds like a good plan. The taller tires drop the ratio down to 4.23. People have good luck with 4.10's so a lil more gear should help compensate for the altitude. Definitly get a converter too.
