Yea I gota 5-speed.

 

does yours cut off at 118?

 

Thats prolly why mine cuts out at 118. I dont think mine came with Z-rated tires from the factory.

 

Ive gone up around 115.. does that mean my car CAME with Z rated tires from the factory? kuz i doubt i have em anymore.

 

huh?

 

im so lost..idw what kinda tires mine came with, i got aftermarket rims nd tires, but my car wont cut out, mine will top out the speedo at 125

 

Same ive got 17in Eagle Alloys and different tires. None of which i have the rating for but ive been at 120, i wasnt there for long but i ran 110 mph for about 8 mins straight and my tires are still the same.

 

damn guys, i have 75$$ z rated tires on my ION [8D]and it tops out at 117 i think in 4th gear, need to get it taken off cuz im like only half way thru 4th when it cuts out.

i dono what my camaro topped out atstock, but itredlined at 95-100 in 5th when i had it. had gears in it tho, even thought the guy before me claims he never did anything to it(he owned it since his dad bought it for him new in 96) jus like it had a EGR valve that was snapped in half, clamped together, and had no sensor attached, a nice shiny driveshaft(alluminum?) 140kmi on it, and the tranny/clutch was more solid than my dad's vette. so im assuming he lied to me, which i dont know why, those are all things(cept maybe EGR) that would sell the car faster, but it seriously had no accident reports or shop receipts, but i found a tire receipt in the manual[&:]

 

Look inside the door where your gross vehicle weight is and everything my car had the stock tires listed right there as Z rated. I don't know if that is true for all Camaros but I know it is for mine.

 

I'll break it down nice and easy so everyone can understand

If your car tops out at 118 or less (my Father owned a '94 Firebird Formula that was limited at 108) it's because it was not ordered with Z rated tires from the factory and has a speed limiter.
If your car can get past that mark and it still has the stock wheels and original tires, they're Z rated and your car is not speed limited. With a Z28 you should be able to achieve speeds of around 140-150 mph.
If you car has aftermarket wheels or doesn't have the original tires on it still and you can get past that mark, either the car was ordered with Z rated tires or the PCM has been reprogrammed to allow the car to achieve speeds higher than the 115 mark.
