What will a 4.10 do to my daily driver?
I love 4.10's in my a4. Would never do anything else. Have done couple hour drives on the freeway with them and with the radio on it doesn't bother me. I would honestly look into more. 4.10's aren't that bad at all.

Dont forget that you should not let these trannies shift into 4th under WOT cause its really hard on them with my car I have 3.73's and go through the traps at 117mph@6000rpms (26" tall tire)so if you are thinking about racing it some and takin things easier on your tranny i would not go anything more then a 3.73 IMO but dont worry about any of this if you wont go above 120 on the street or never take it to the track
Thanks guys! I obviously want to make it faster out of the hole, but I have to keep it practical. I can't afford to break it, I don't have a back up! 3.42 sounds about right!

Man, you guys are killin' me! I can't wait to change gears and put in a stall!! That's freakin' flyin' with just a few mods! That's faster than a new stock Camaro SS and any stock Mustang.
No weight reductions either .Probably heavier than stock with the OE ZR1 wheels
A couple of minor mods too . But thats it .
Mods are :
Yank SS4000 stall ( biggest improvement ) 373 gears w/ Nitto 555r drag radials
BMR lca's
ORY/ stk ex manifolds. ( dont know if it made it faster , but it sounds cool)
Magnaflow Cat back
SLP lid w/ K&N & free ram air mod
Basic Dyno tuned .
Cut a 1.72 60 ft 3 times in a row . Now I have LT's and a TSP catted y waiting to go on .Going to remove the ft sway bar and spare tire next time too. Should net a 1.6x 60 ft. Maybe some high 11's in the late fall
A good stall will make a world of difference in ET .
The only down side is ,its hard to drive with regular street tires . My 315 35 17's d/r's have a hard time sticking in 1st gear .
Hey Eddie, what's your car like on the interstate? I was set on a 3.42, but my mechanic is a serious drag racer, and he tells me to put in a 3.73. He said it won't hurt my mileage that bad, and it won't be too strenuous on my engine. What do you think?
Not Eddie either lol but I too have 3.73's, on the highway its not much different than when I had the 3.23's, RPM's are noticeably higher so I try to reduce speed just a little and compensate. At 70 its

not tryin to jack the thread. but you guys seem like the ones to ask. im running a 305/40/18 on the rear (27.5"). i want to go with a yank ss3600 but stuck on gear choice.. i was set on 373s but now after installing those tires i feel like i might should go 390s. im doing 2100rpm at 70mph (gps speed because the speedo is way off with the new tire). the low end suffered alot from this tire size thats why im kind of leaning toward the 390 also now. what do you guys think?

ive got 323s in it now. the car is a weekend toy. motor and drive train are all stock, blackwing/CME car but like i said the new tires made it feel like a turd off the line. with the 26' tire i was set on 373s but now i just dont know. i feel like the 390s with the new tire would almost be the same as 373s with the old 26" tires i had....
