Can't Find Gear Ratio
 
1 Attachment(s)
I can't seem to find the gear ratio for my 02 Camaro Z28.

I took a picture of the sticker in the door jam, and I do not see GU* anywhere. I also looked in the glovebox and nothing.

It's an 02 Z28 A4.

See pic below:

Who told you its on the door jam sticker? I don't have a 4th gen, but look on the axle housing. For sure its on the ring gear.

Get the VIN # AND CALL A DEALERSHIP ask for parts and tell em u need to find out the gear ratio for your car and provide them with VIN #..

Cool, thanks, looks like it's 2.73. Time to upgrade to 3.90 :O

Get the car on the hwy in lockup.

If it's 1500 at 60mph, it's 2.73. If it's 50mph at 1500... 3.23.

Not trying to thread jack or anything, but what gears would I have if my rpm's are at 2500 @ 70 mph?

What tire? 3.90 if stock 26" tire.

245/50R16, factory wheels. It's a A4 if that matters at all.

It's a daily drive of sorts, but I only drive it like 5 miles a day. I have another car for long distances.

I have plans for it to hit the track eventually.

Is the guy the origonal owner? May have been swapped out....

Just make sure it's in lockup and look at your speedo and tach. If you know the size of your tire, it's very easy to figure out your gear ratio...
