I've come to realize, after riding in some other peoples' cars of different makes/models, both new and old, that my rear brake bias seems to be lacking. I assume the 13" wilwoods up front likely exacerbate this. I've been looking into a rear prop valve, but due to the diagonal configuration of the factory proportioning valve, and a 1:1 A/B configuration from the master cylinder, i may want to delete the booster, install a Wilwood master cylinder with a 2:1 A/B configuration, and an adjustable proportioning valve to modulate the rear better, especially for AutoX duty.

I'm unable to find any info posted anywhere regarding the factory brake pedal ratio. I'll have to measure it myself, i suppose.

Has anybody on here done an aftermarket Master Cylinder and prop valve? I'm not looking to go with a dual master, moving seating position back, modifying firewall, or extending a steering column for a full on "race car" setup, but something a bit more simple yet effective. The dual master thing is something i'd only want to do around the time i decided to put a cage in the car and take it to a track on a trailer... Which will not likely be ever.

It SEEMS like a chasebays booster delete kit and a tandem MC from wilwood would work wonders, provided i have a decent pedal ratio. I'd expect SOMEBODY has done something like this with these cars, right?
