Works fine. if you want your master cylinder on the same side of the firewall as the driver then reverse mount is the way to go. These are expensive, but unfortunately worth it. stock brakes for a street stock class are prone to problems (leaks, vacuum issues, etc) and heavier than this setup. I would like to see the price lower, but no issues with quality, fit or finish.
Pros:
  • Stops 3500lb car
  • Installed easy
  • No leaks
Yes, I recommend this product.

This pedal mounts two brake master cylinders with a bias balance bar and positions the master cylinders inside the firewall and away from engine heat. The pedal features all aluminum frame and arm construction with steel pivots, mounting studs, and an anti-skid pedal pad. Wilwood's clevis and pivot pin balance bar provide smooth and accurate settings of the brake pedal bias. It can be set and locked down with the jam nut, or attached to a remote cable for quick on-track adjustments. 6.25 to 1 ratio is offered in this unit to suit your mounting and leverage requirements. There is no place designated for a brake switch and would be up to end user how/where to install.

You inquired about some dimensions on the pedal assembly on part number 910-29972 and specifically from the master cylinder to the pedal pivot. I have the overall dimension in depth from master cylinder to furthest most point which would be to the outside or forward of the actual pivot point and that is 4 5/8”. Width of pedal assembly is 5 3/16” and height from top of pedal pivot point to bottom of pedal is 14 ½”. Wilwood also has an actual blueprint on their website on all their products which is helpful in determining fit.

The specific brakes that you are using as well as the caliper piston sizes would be helpful in specifying master cylinder sizes. 7/8" for both front and rear is a commonly used master cylinder size. Also a 1" front and 7/8" rear master cylinder can be used if you need more rear brake bias.
