You're welcome, actually I made this for my personal reference as well!

Some of the rear caliper brackets weren't rotated down Kohburn-style, so they don't have rear pad interference.

The subaru rotor looks nice, but the limited factor may just be the rotor hat. I will have to look into this....

Also Wilwood makes many different calipers of different bore sizes to replace the GM Metric Caliper.

There is a guy here that runs Subaru 13" brakes on his weekend racecar and swears that they are the best and easiest upgrade.

Do you have any more info on this upgrade?

I've been seriously considering using these rotors:


as opposed to the lebaron rotors:


The size difference isn't much, The lebaron rotors are 11.27" and the Subaru Forester rotors are 11.56" The offset on the rotor is a bit deeper, don't know if thats ok till it's tried. They weigh the same, but the Forester rotors are thicker. I found that the Cadillac calipers, with the pistons completely retracted, and with new pads measure 1.2" between the friction surfaces, but they can only be used practically to about 1" thick. The Lebaron rotors are only .870 thick, and the Forester rotors are .945" thick, so there is a slight advantage there. The snout on the Fiero's bearing is the same size as the both of the rotors too. They look like a perfect fit. They vent from the inside, as opposed to the lebaron rotors venting from the outside. If these rotors work, it's a nice alternative, but it might rule out factory 15" wheels, as it would push the calipers out .129" and that might be the point of scraping the wheel... or maybe not?

They are more money but they are somewhat a better rotor. I just wonder if they would fit over the hub's hat OD. These look a bit small in that dimension.


Anyone want to test these?




What's the rotor application again?

There are also BMW rotors that *should* work... They have a 5x120 bolt circle, so should work for those swapping to 5x4.75" lug circles.
