Well I just got a new set of tires for my camaro a couple of weeks ago and after I burnt the rear passenger tire down on my old set, i've decided its in the best interest of my new set of tires to get a posi. I'm lookin to put a new set of gears in it too. It's my daily driver so I dont want anything too tall in it, probably a 3.23 or a 3.73. My question is how much of a difference will a taller gear make? As it sits right now it only has a 2.73 in it.

 

itll be a short shift through all the gears and a short first gear. i just did a similar swap

 

FYI a the bigger the number, the smaller the gear, 2.73 is a tall gear, 3.73 isint

 

Oh I see, duh that makes since
Thanx for the info

 

Here's an interesting link about gearing:

And another about gears and limited slip:

You will see a big difference if you change gears and go to posi too.

 

Don't do burnouts and you will save your tires. A limited slip rear is not the cure all for tire wear, but your burnout habits.

 

i just got a 3.42.
sounds just like what you need

 

Lol very true, I've layed off since ive got new tires but she still likes to spin a little when i get on her, so im hoping with a limited slip it wont spin or will hardly spin, if it chirps i dont mind i jus dont wanna see smoke til i let off her

 

How much did you pay for your gears and posi? I pulled a rearend out of a 88 GTA so I dont need a posi but It ended up comin with a 2.73 so I need some different gears.

 

I'm unsure what that means. If you romp the car, the tires will still spin with a limited slip. Burnouts? You bet.

Well the car tends to spin a little even when im not rompin on it, so im hopin this will help out with a little better traction. Yeah, cuz 2 wheel burnouts are definetaly better than 1 wheel burnouts.

 

i bought it from a guy on here for $150. Its from a 95 camaro so the wheels stick out an extra inch on each side.

My cousin has a 3.73 in his 91 Z28, and hes constantly shifting, so i think its just right(mines a daily drier too)

 

Well thats not a bad deal. So are u sayin he 3.42 is perfect or the 3.73?

 

Few years back a hotrod mag shootout said 3:55s were best for street strip

I say 3:42s

Though don't forget effective or what ever ratio. Your tires come into play.

Why ya see them with 5:? ratios but they got 4ft tall tires.

Lots of science to it.

run your tire size n ratios though a calc to see what ya get.

On my V8 car, stock is 225/75/15 on the rear I run 205/70/15
It effectively changes my ratio and is better for getting the tank moving.
And stay in the RM range I want for a said speed.

 

What major mods have you made to the car? Is this the 305 TBI in your stats? Unless you've made some major mods, and some major chip tuning to go with it, you've got some kinda problem with the car, or some kinda driving issue.

There's no way you can expect me to believe that your 305 TBI (if stock or close to it) with a 2.73 peg leg is spinning wheels badly enough to wear out your tires - I've owned 2 TBI cars, and a 305 carb car, and it's just not possible without some major mods or a definite problem (like your front brakes are catching). Even my current set up won't spin without making it - but it will chirp 1st and 2nd

So, you've either got an issue that needs fixed with the car (stuck caliper, bad proportioning valve, etc.), or with your left foot on the brake. As mentioned, a posi isn't going to solve your problem.

But if a posi is what you want, 3.42 is a great street gear - great seat of the pants feel with decent highway economy. If you can deal with the extra inch or so on each side, a 4th gen rear is an easy cheap swap that gets you posi, gears, and rear disc brakes in one simple easy 4 hour do-it-in-the-driveway swap.

 

well it really depends what you want out of it. if you want to save some gas and a little pick-me-up, then go with the 3.42 for sure. 3.73 has alot shorter gears so you loose some fuel economy.

But i have always been a fan of the 3.73, So theres no bad choice

 

Well I wouldnt consider it heavily modified, headers, chip, underdrive pulleys, open element, cat delete, high flow muffler, smog stuff removed. When its dry out you gotta give it a little more gas, but she starts to spin on me. And when its wet out I dont even try and hit over half throttle. I'd jus rather burn both tires a little bit than burn one tire alota bit lol.

But i thought that since a posi spins both tires it will grip better?

See I thought about the 4th gen rearend but Im kinda sketchy about the 1 inch look.

 

Another quick question, would the posi out of the 88 GTA rearend be a series 2 or 3 carrier? I found a 3.42 gear for my rearend but it needs a series 3 gear

 

The limited slip would be a 3-series out of the 88 GTA. Howerever: It could be a 9-bolt, have 26 spline axle shafts, which means none of it would work in your 1992 model

 

It could be a 2 or a 3 series. That will depend on what the gear ratio is. If it has a 3.08 to 2.41 then it will be a 2 series. If it has a 3.23 to 4.10 it will be a 3 series. That is if it has the 10 bolt. If it has the 9 bolt then none of the parts will fit in the 10 bolt anyway.
