anyone with the knowlegde about good brakes...

my current brake setup (ls1 front calipers and rotors and rear lt1 rotors and calipers) is starting to shake the car pretty bad when applying the brakes...
i have a proprtioning valve which is open the whole way so that all four brakes have equal force being applied.

what rotors and calipers do you run on your non abs system or which would you recommend?

Are the rotors warped? If you can get to an area where there is no traffic/obstructions, adjust the proportioning valve to only use the fronts, and then only use the rears, and see which "axle" is producing the issue. I think it's going to be either the rotors, or maybe a caliper is not functioning properly.

 

warped rotors does it shake the steering wheel if so front it is
