my car has mac-mid lengths w/ 3" y-pipe, mti lid, accufab tb and a fuddle 4k 2.4 stall...i get 1.8x 60fts spinning with crappy 245/50/16 nittos and dropped .8 with the addition of the tb and stall but with little traction...i've been debating wether to get 3.73s or 4.10s (i'll probably be adding lca's and maybe a torque arm also for traction) and i've done searches and am still unsure, my car is my daily driver and i drive about 30 miles to and from work...i'm not concerned with drivability nor gas mileage but would 4.10s put me into od at the track? i dont wanna hit the rev limiter either at the end...also i dont wanna get 3.73s and end up regreting not getting 4.10s...any input would be appreciated...thanks

Definetly do 4.10s. I have 3.73s and they are okay, but now I am about to upgrade to 4.10s cause I need more!!!

Ummm which trans 350/400 or 4L60/4L80E..

Tire type and diameter..

Drag radials vs slots etc...

2.4 STR + 4.10 gears = more uncontrollable launches. I would say get stickier tires and go with 3.73s. Or do slicks and 4.10s along with a new differential (if you still have the stock 10-bolt).

i still have the stock 4l60e with 245/50/16 nittos...i'll probably upgrade to 26x10.5 et's on the stock 5 spokes...and i still have the stock 10 bolt ...dont really go to the track though but even then drivability never bothers me

V8_DSM_V8again

I'd get 3.73's and when you kill the 4l60E get a lower first gear installed in a 4l80E.

Consider a axle swap too..

you may want to pay attention to the mph/rpm you will trap in the 1/4. Im sure that with 4.10's your going to run out of gear and hit 4th gear which will slow you down unless you go with a taller tire and rev the **** out of the motor..

Your having traction problems now and your thinking about 4.10s? I would worry about getting traction before you add another mod to make it a lot worse. I was able to hook with 3.23, 4000 stall, 399rwhp, a lot of suspension and bfg drag radials, I went with 3.73s and no more traction, 4.10s will be even worse plus even if you do hook your 10 bolt will hate you. 4.10s are a good option if you want to upgrade your rear and put on taller stickier tires and add most if not all suspension parts. Otherwise I think even the 3.73s will be pushing to the point of no traction.

if your running a 6-speed i would go with a 4:10 an automatic a 3:73

agree with redhot here, . . 3.42 in the stock manuals, . .heard you won't feel a difference if you swap to 3.73's, ..so people with manuals tend to go with 4.10, 4.11's stock auto is like 2.something right? so many autopeople go with 3.73's for a huge leap, . . 4.10 on an auto is pushin it

I just bought 3.73's, not in yet though. My buddy has 4.10's on his 99ss m6. Name of the game is traction in my opinion. If you're not gonna go all out in the name of traction, then good luck making use of those 4.10s. Im willing to bet w/ mediocre traction you'd be better w/ the 3.73's. Once you're into 3rd you're gonna take a slight loss because of the 4.10's. Just my .02

w/ A4 go 3.42 and 3.73 w/ M6. I went w/ 4.11 in my 12 bolt and regret it. Street manors suck. I powder the Nittos and can't hook to save my life.

I would learn to launch the car first without spinning. Those nittos aren't as crappy as you think. Stop trying to floor the car out of the hole, you gotta make sure the car hooks first before you give it full power.

Very good point.

Another thing is, I'm so sick of everyone saying 3.73s for a4 and 4.10s for m6, thats such a bullshit answer. Every setup is not the same, you don't just slap in 3.73s because you have an a4. It is much more complicated than that, it all depends on other mods and what you plan to do with the car. If you plan to use a regular street tire than you might as well leave your gears stock unless your goal is to break the tires loose every time you want to show off but go slow doing it. If you only have drag radials and stock susspension then 3.42s could be a good choice. If you don't mind going to a better tire and doing some traction mods 3.73s can work or even 4.10s with a taller tire can be a good choice. If your going all out drag car your most likely going to want at least 4.10s. For the person that started this thread, I don't think gears are the best choice for the next mod. Work on getting traction first. Then once you got the car dead hooking you can start to think about where you want to go next, just remember once you change gears your going to either need to relearn how to get the car to hook or put on some fat sticky tires.
Sorry for the long rant.

Get your launch down first, then after you do that, either add power or add suspension. I was able to launch the car at 4000 rpm and she didn't spin but the trans couldn't hold it. Shame too.

rufretic

Your also launching with 2.73s, thats why your not spinning. It's not so easy with 3.73s or 4.11s. Thats why tires and traction mods become more important with lower gears.

Roarin_8

I know, which is why he shouldn't go with steeper gears if he's still spinning. He didn't post which gears he has though.

rufretic

iTrader: (37)

Exactly, it doesn't even matter what gears he has now. If he can't hook, gears are not a great choice for his next mod. The only reason I can see going with say 3.73s with his set up is that the converter won't feel as loose. It won't help performance though because any time he wants to hit it, hes just going to sit and spin.

Roarin_8

Yeah spinning is no good. He should skip the gears and go for the LCAs and torque arm.
