Your fronts are simply 92+ brakes, since your car was a 90 and had the smaller fronts.

The rears I can't put my finger on what they used back there, and its not the same as the Baer kit thats out there for J-bodies.

agreed on the fronts, although i pais for his 11" hd upgrade.
the rears, as he is a gm guy, i have to believe they r from another gm product.
the rears have 10 bolt holes in them, the rears r not ventilated(front are)

? r the fronts 90 and 92+ ventilated.?

? have u ever seen a disk with 10 holes, or is that the custom part of it..?

? in my rear upgrade, does it mean i got a new hub (etc), or do i still have my oem hub?

Going by the pics, the 10 hole pattern could simply be due to the fact that he used a 5x115 setup and had to redrill a 5x100mm setup to match the hub, this is also very possible since he also had to use a centering ring to center the rotor to your hub.

You have factory rear hub's style wise... I doubt he replaced them with new ones since he short changed you on the fronts.

stock 91 and older brakes are vented yes, and actually the original 91 and older rotors are slightly thicker than the 92+ ones... I have the older rotors on the rear of the red car to fit the bracket I made.

Also factory 92+ is vented as well...

My setup as you know is now 12" vented fronts, and 10.6 non vented rears with internal parking brake drum.
