Brake calipers for road race rotors
I picked up a used road race car (roller) but it didn't come with brake calipers. The guy had some super expensive AP racing NASCAR brake calipers on there that were way out of my price range.
The front rotors are pretty massive, 13" diamater and 1 5/8 (42 mm) thick. I'm looking for entry level calipers that will fit this... haven't had much luck finding something yet. It seems that these are thicker than anything I can find available.
The rear rotors are a more reasonable 13" by 32 mm thick.
Any suggestions?
Thanks,
Sal

Biggest AP calipers I am finding is 50sq-cm which is 7.75 sq-in.
Anyway really doesn’t matter. It’s a ratio of piston area to master bore area and pedal ratio to get clamping force. And then it’s sizing the rears correctly to get the right front rear brake ratio.
In the wildwood line I would go with the aero6 stuff and the larger piston size which I think is 5.4
What masters does the car have?
With a PA of 8 or so it’s probably 1 1/8” maybe even 1.25”
The wildwood probably needs more like a 7/8”
My ST60s with a 5.9PA use a 15/16”
That’s assuming a manual brake system.
Some rough numbers to give you a starting point. Really need to do all the math to size it correctly.
