Hey I was just wondering, everyone says that you can recognize a B4C by the disc rear brakes. So does that mean there wasn't an option to get rear disc's on a stock general public available RS in '91 and '92?? This sounds strange to me, I mean why not put it out there as an option?

But the real question I have is, Is it true that a non-B4C RS camaro couldn't get rear disc brakes in '91 and '92?

Thanks, Garrett

 

i HIGHLY doubt it

 

I don't think so either, the Camaro White Book says the the G92 is a Z28 only option in 91-92, and I beleive thats the only way you could get rear discs.

So no rear discs on RS's that aren't B4C's

 

The only way to get 4 wheel disc on an RS was the B4C package, this package came with the 1LE 12" rotors and PBR dual piston calibers up front, standard Z28 PBR discs in the rear.

 

I think GU5 was always a stand alone option....

 

RPO for 4 wheel disc is J65.

 

whoops GU5 is 3.23:1 rear gear, pffft what was I thinking

 

you threw that code out to make sure we stay on top of all RPO codes didn't you???

 

I have a 1991 Z28 5.7 TPI (L98) completely loaded......but.....dosen't have rear disk brakes...RPO codes says J65....it has drum on the rear...maybe someone changed the whole rearend before I bought it??..

 

GM had a problem with the manufacturer in 1991 and ran out of rear discs and began to use drum in the rear even though it had a J65 code. kinda weird. In 1992 problem was solved and they began putting the rear discs back on the RPO J65 cars.

Don't flame me if I am wrong but I heard this from a pretty reliable source, anyone else heard of this?
