Is it really at 115mph? I got my V6 Camaro to go 118mph with nothing done to the limiter. I don't know any way around the limiter other then getting a chip.

It's 118 on Zs if you didn't order the high speed tires.
It's 163 if you got the right tires.

I had the same issue. I bought my car off the lot with the factory ground appearance pkg. Little did I know that included the steel driveshaft and narrow tires. I first found out about it on the dyno, when it cutout @ 5400RPM in 4th.

I temporarily borrowed another VIN with the same options and got rid of it that way (after upgrading the tires). I later had the PCM tuned so it didn't matter.

The VIN was reprogrammed by an acquaintance at a dealership for nada, btw.

I would look for one that is used instead of buying a new chip to save yourself some money.

Well, mine stock didnt' come with z-rated tires and came with the steel driveshaft. The limiter is like 115 or 118 or something, I hate hittin that damn thing, I forget it's there, and it almost shakes me out of my lane! I really just want to get rid of the damn thing for free or really cheap!!! My boys have to stay at 115 or lower, or else I can't keep up when we're cruisin, it sucks!!!!!!! Plus, everytime I get a race on the highway, it sucks havin it!

The SS's doesn't come with anything other than Z-rated tires. The only one's that you could possibly get non Z-rated tires with are the Z28 or the V6. So yes stock F1's are Z-rated.

For the Z28, the optional z-rated tires are Goodyear GS-C's in 245/50/ZR16. I'm pretty sure the standard equipment RS-A's aren't Z-rated, hence Z28's with the 118 mph limit. The GA's only came on V6's.

EDIT: The RS-A's are in fact z-rated. So I guess no 2002 LS1 Camaros have the 118 mph limter? Were there Z28's on GA's in previous model years?

Correct, to my knowledge, all 2002 LS1'd Camaros (and I would assume Firebird and T/As) came standard with Z-rated tires (RS-As) and there was still the $225 option...for the GS-Cs. IOW, no limiter on the '02s.

96FLZ is right. You shouldn't have a speed limited to 115 and you should have z-rated tires. I have the GOODYEAR RS-A'S and they are z-rated.

Sorry, but you're wrong on that one....................until 2002, Z28's could come with non Z-rated tires and a factory programmed ~115mph rev/speed limiter.................however, for 2002, they (Z28's) all came with Z-rated tires, and a rev limiter that's a lot harder to reach! (although, with a good stretch of road and no traffic, it does exist!!!).

I don't know if it's been mentioned or not, but the easiest way to tell if a car is limited low or high is to look at the speedo.
The low cars will have a ~115 mph speedo.
The high cars will have a ~150 mph speedo.
