Easy way : Check the RPO codes in your glove box or door jam

Fun way: Nail the gas and see how many stripes you lay down

RPO Codes (I know there's a better list around here somewhere)

i say mail the gas and accidentally have your foot on the brake as well, but that is just me.. I liked buying tires.. LOL

 

I checked the codes in my glove box and the only "g--" on my car is a GU4, which is not listed on the list. I dont have the "G80" code in my glove box, which is the slip rear alxe.
I have done burnouts before but never go back to look at them, except once which was not a very good one. So I really cant tell by that yet...maybe I'll have to give that brake a lil tap tommorow at work and take a look, hehe. Hopefully both tires spin.....

 

I checked all my RPO codes on camarosource and they didnt turn anything up about a slip differential. Only thing I found out is that I have a 3.08 gear ratio (I dont know much about gear ratios, but I dont think its good, haha)

 

GU4 is a 3.08 ratio
If you don't have G80 you're spinning one wheel.

 

Most 4th gens came with 2.73, 3.08 or 3.23 gears.
(numerically) Higher gear ratios mean that the driveshaft turns
more times per wheel rotation. So (numerically) higher ratios
make you rip through gears faster accelerate faster. At the same time
that means you are at a higher RPM at any given speed and are burning
more fuel.

I've run 3.73s in my 3.4 and my 5.7. They are awesome.
Just be sure to have them installed by a pro or they whine line a banshee.

that might be the dumbest question ive ever seen.

 

Followed by the rudest answer.

With the car in 3 or OD;
Hold the brake with your left and mash the gas with your right.
Slowly let off the brake and let the car roll forward to make a nice long burnout.

Hold it down longer tomake a huge smoke cloud on the spot.

FAIR WARNING: Do it long enough and you will wear the tire down so far it will explode.

 

You put it in OD? I've never tryed that....

 

Shouldn't matter much, if any.
I think on the 700R4 and 4L60 (not E) ended up with more line pressure when you left it in 3.

The goal is just to have the car (or wheels in this case) accelerate while keeping it in one place.
The front brakes hold the car from moving.
