I recently purchased the Toyota vented 4 x 4 caliper kit from Ross at Modern Motor Sports.

I finished installing the MM vented rotor 4 x 4 kit and the brakes are awesome! The pedal is high, firm and modulates well after properly adjusting the booster push rod and taking some slack out of the brake pedal travel. The car hauls down confidently at every stop. Here is what I did:

-New (remanufactured) Toyota calipers from a local dealer: $117.00 ea. I clear coated the calipers preserving the clean looking castings.

-1979 280zx MC (bench bled) with the booster push rod adjusted to 10mm past the aluminum spacer.

-Recent rebuild of rear drum breaks with MSA shoes (look like KVR shoes.)

-Adjusted slack out of the brake pedal travel.

-3/8” wheel spacers were required because the caliper cylinder blisters just rubbed on the outer edge of the hub of my 15” Eagle rims. I may be able to go to a smaller spacer. I had considered grinding the blister, but I was not sure how much material surrounded the cylinder.

Only the fronts lock up in a hard stop. I could never lock the wheels on either of my stock 240Zs.

Good deal, I have been thinking about doing this swap.
