This may sound like a stupid question but do all the 91 & 92 Z28 come with rear disc brakes. Thanks

 

Nope.

------------------
'84Z28/'92 305TPI
'92 complete rear suspension/PBR disc/Posi/3:42
Light weight 34.5mm stabilizer bar in front
23mm sta. bar in rear
rear lowered 1" by cutting 1 1/4 coils of '84Z28 springs
comp cam, flowmaster
TB coolantbypass/shutoff valve to heater core
MAT relocated
Ram-Air(home-made) gutted air-box
IROC ground effects/wheels GY245/50's
700R4 superior shift kit/ corvette servo(excellent shift kit BTW) Rebuilt engine and transplanted it myself. Love this engine!
LOW performance people should drive low performance vehicles!

 

So then was it an option or what? Does anyone know any good websites that tell alot about the differences betweed RS and Z28(Iroc)?

 

Yes, it was an option. The 305 automatic TPI and the 305 manual TPI without the G92 performance package had drum brakes. The 305 manual TPI with the G92 package, and the 350 automatic TPI got the disc brakes. Exceptions have been noted but this is the general rule.

All RS's had rear drum brakes, except for the 91-92 B4C police cars.
