i know someone who has 4.30s in a 9 inch. he drives it on the street all the time. He runs a taller tire at the track though thats why he got them i guess.

I'm currently running 4.30s. Nothing against them , but I recommend 4.11s prior to the 4.56s. It'll keep your engine rpm down on the highway and still give great reactions at the track. . .

i run 4.56's in my m6 gto but i also run a 28" tire in the back. at 60 in 6th i am doing around 1800rpm and @80 i am around 2300. just add about 3 to 400rpms to that and that is what it would be with a 26" tire

Why 4.56s' in my A4,I'm old school from when gears ruled the streets.
It's a daily driver except when it snows here in ohio.
Torque,Torque,Torque! Torque accelerates,horsepower maintains.
I'm 'old school' from the 60s' when torque and gears ruled the streets.I've worked on rearends back then so they are not something to avoid working on.Back in the late 60s',you could get factory 4.56s/4.88s in your car order in camaros,novas,and chevelles.They were great 'light to light' streetfighters.So why not build a rearend for optimal 'light to light' streetfighting.I have 3 extra rearends(take-outs from f-bod),many gearsets(from swap meets and Summit 'discount returned items,2.41,2.73.3.23,3.42,3.73,4.10,4.56),various carriers(auburns,torsens,and eatons).
When I decided to take out the OEM 3.23 rearend(passenger side carrier bearing was growling),I figured why not build a rear with the $25 used richmond 4.56 gearset I picked up at a swap meet.That rearend was put in in sept. of 07 and I haven't regretted it since.1st and 2nd(with Nitto 315s on the street)are incredible.I've taken 3 trips to florida from cleveland,ohio with the 4.56s' and the computor has handled the mpg better than originally anticipated.24.5 mpg with the 3.23s,now 21.5 mpg with the 4.56s.No complaint here.Freeway rpm would be considered high,but I don't.It's designed to work in a range.Coming back from florida a few weeks ago,we hooked in with a fast traveling group on I-95/I-26/I-77 in South Carolina that put us in cruise control at 4000 rpm for a couple hours.The engine now has an incredible mechanical advantage over the car and it operates at a condition of not being under a load.
