When I have these calipers rebuilt I cange the pistons for slightly bigger ones to give slightly better braking.
Thanks for the info classicswede. So the 4 pot calipers will bolt onto my steering knuckle, but will I be able to run my stock rotors?

I would be very interested in your balance bar brake pedal design. I dont think there is any room to mount the Wilwood assembly lower down. The pedal could be modified in length but that would give a ratio about 8.5:1. Is that too much?
How would you mount the Wilwood bracket? Would it fasten from above?

Thanks for the link. At this point I think I'm just going to run rebuilt stock calipers to keep it simple. At some point in the future I'd like to design a completely new front end that uses the steering knuckle from a newer car that can run a big rotor and a nice caliper, along with a custom K-member to run adjustable tubular A-arms and a rack & pinion for steering. That would be a nice upgrade.

I'm also thinking that the Wilwood assembly won't fit when mounted lower down. Most brake design articles I've read say a pedal ratio of 5:1 to 6.5:1 is the ideal range for manual brakes. Any modification of the Wilwood pedal arms would take the ratio to way over 7:1. So yeah I think the custom brake arm is the way I'm going. I'll definitely post plenty of pics and dimensions of it when I get to that point.
