I need help identifying this brake kit.

I bought the brake kit used I was told came off a 3rd gen camaro. I was also told it was a WilWood 10.75"x0.81" rotor kit. http://www.summitracing.com/parts/WIL-140-2992-BD/

After I looked at the kit closer last night I realized the rotors are pretty thick I measured them at 1.25" and rotors slightly larger than 12" (probably the 12.19"). They have directional vanes. Did Wilwood make a kit for our cars in that size? I also noticed the calipers are 2" 4-pistons and stamped JFZ on the side. The calipers also fit the rotors.

I was planning on selling it for a C4 kit, but I might just use it if I can figure out where it came from so I can get replacement parts.

 

that was on ebay wasnt it? if i new it was a 12" setup, i would have picked it up.

do the caliper brackets position the caliper correctly on the 12" rotor? is it possible somebody replaced the rotors with a larger size and never used them afterward to notice a difference? or he just supplied the wrong rotors?

 

Yep I got it off ebay. Originally bought it to flip it, but I might just use it now. Considering the thickness and size making it basically the same as an LS1 kit but with 4 piston calipers.

I don't have a spare spindle to check alignment of the bracket. I was told it was used for a mockup and sat for 8 months. There are markings on the rotors from the calipers sitting which makes me think it did sit.

The bolt pattern is different on these hubs... These are 8x 7" compared to the 6 bolts on the normal shelf kit. It's almost like there was a beefier kit at one time or someone bought parts of a beefier kit and adapt'd to the spindle mounts.

I was just hoping someone knew something about a kit made like this or the JFZ calipers. The pad design leads me to think there like the JFZ/Sierra XL pads.
