Looking for some proof. 4.10 vs 3.73
 

I know everyone says that if you have a 99+ you MUST GET 4.10's. However, I'm having a hard time finding results as in ACTUAL 1/4 mile slips to compare the differences between the 4.10 and 3.73 gear.

4.10 obviously has the better "SOTP" feel, I understand that, but that's not enough evidence to show that it truly is better.

I want what's best for my application and not for the feel in the seat of my pants :tup

If anyone has input, please chime in.

After driving a mod motor car with 410's and a 5spd I opted for 373's in my own car (2000 GT). SOTP was great with the 410's but it made 1st gear all but useless and the car a drag on the hwy. More than pleased with my choice.

I went with the 3.73's aswell.In 1/4 times i've run the best of 13.7 at 103 mph,i've also spit out 105 mph a few times.That is with stock tires,and my eibach sportlines springs.
Damien2003gt has 4.10's and hit 13.2 at around 100 mph with m/t et streets,and eibach pro kit springs....but with a nice rpm launch though :confused: . :biggrin:
I imagine with a set of slicks and 3.73's,it wouldn't be that much different then 4.10's.
After seeing you run in sparta,you need gears :bleh: .Especially with those cams :tup .
Those vt II's need gears better then stock.If you were closer,i'd let you try my sled out to see for yourself if you like 3.73's :cheers: .

I love my 4.10's

I really wanted 373's when i first got my car and it was what I was set on doing and then ZAVKE showed me the light.

I cant wait till he sees this thread lol

How did he show you? Did he take you out in his car?

I'm not looking for an improvement in the seat of my pants, but rather an ACTUAL gain in the 1/4 mile. I have yet to see ANY proof of a 4.10 gear getting better times than a 3.73 in the same or comparable car.

if you want a difference get 4.30's lol :biggrin:

Last year I took a ride in Bobs car (retread) and he had 373's in it, at that time i still thought I wanted 373's but I didnt notice hardly any difference with the 373's (rpm's drop when shifting) then one day in kitchener Vedran took me for a rip in his car with the 410's and I noticed a huge difference and Vedran explained the gear ratios in the 01+ etc and I knew 4.10's are the way to go. He even said If I dont like the 4.10's he will pay for my 373's and install and keep my 4.10's.

But from what Ive been told the 99/00 have a different gear ratio in the T5 and factory gear so with 4.10's you would be reving higher than in an 01+

I'd love it if someone could explain the benefits of the 4.10 vs 3.73 for my car. However, people just say "it's a better gear" without knowing why or if it really is.

Raf, what effect did the 4.10's have on your 1/4 mile?

last year I ran 14.301 with a k&n and flowmaster mufflers with a 2.27 60 foot

this year with 4.10's O/R X pipe and M/T I ran 13.7 with a 2.0 60 foot

Everyone says it takes away .5 seconds

i dont have a 99+ i have an 88 lx but im also auto and i hit a 1.80 60 ft with 4:10's and M/T et street radial tires. Dont know if that helps u with ur pick thats just my 2 cents.
