This will not work on our cars.

Our valve splits initially left and right, then it splits front and rear. It could work if you ran new lines from an aftermarket proportioning valve.

Nobody here is ready for this and there are other ways to get more rear brakes if that is your goal.

Leave rubber brake lines on the front and use stainless on the rear. Use a more aggressive rear pad and a softer compound in the front. Remember the rear disc rotors are not vented, so you might consider cryotreating the rears to prevent warping.

I have autocrossed my car for a few years now and researched hard the benefits of adding two russel brake proportioning valves to my car. If I was only driving on oval or road courses, this might be worth the effort. As it is now, my setup is fine.

If someone decides to go down this road, keep us posted.
