What Chevy had an 11" diameter, 1" thick rotor, and used 5.5" spread metric calipers?

Looking for some metric chevy calipers to use with TJ rotors for a rear disc conversion using the AA mfg weld on caliper mounts.

Monte Carlo, for one... I think. 5.5" is the smaller caliper, right? I have a pair on the rear of the Heep on 1" rotors, from any number of mid-70's chev cars. Common as hell.

Yeah, 5.5" is the newer, smaller GM "Metric" caliper for 1" calipers. I looked at some last night at Schucks for an S10 4x4 Blazer, but they were for 10.5" rotors and I need them to work with 11" rotors. I wonder if the Monte Carlo and other GM cars had 11" rotors....

I don't think it matters. The height of the caliper mount is what determines rotor diameter, not the caliper.

That's kind of what I was thinking, but the pads are radius'd for a certain diameter rotor aren't they?

Maybe, but that's only 1/4" difference in radius..........

Good point, that's a real minimal difference. I think I'll give them a try.

raybestos#5100 is a 11 1/64 diam. 1.035 thick with5on4 3/4 pattern need more info post.this rotor is what they calltype j which is rotor &hub all in one.hope this helps.

Interesting, do you know what rigs used them?
