I've hated my brakes ever since installing the 1" wilwood master and big piston dynalites. This weekend I gave up on trying to get it working with the wilwood master and swapped a NB 15/16" master and NB booster in place. Now the car has 11.75" rotors up front with 1.38" dynalites and 11.75" in the rear with 1" dynapros. I'm hoping the prop valve can dial out the extra rear bias from the larger rotor in the back. Looking forward to the next track day where my brakes don't suck.

The spacers are there just to have the street wheels fill out the body kit. They aren't needed for 6ul clearance with the caliper.

 

What pads are you going to run front and rear? Is that a radial mount dynapro?

 

Presumably not, since a lug-mount DP4 will bolt up in place of a lug-mount DL4. Not as light as what our rear kit will be, but the same bias effect. You'll be quite pleased with the results.

 

I have xp12s on the front and back, but I want to switch to dtc60s to save my wallet. It's a track car and I'm not particularly worried about rotor life or dust since they have never been an issue. Cobalts are another option assuming they last long enough to justify the cost. Getting pads for the dynapro lug mounts isn't as easy as the dynalites. It's going to take time to swap out various pads to see what works best.
