Lets start at the begining.

Lots of ways to modify the peddle or just move the whole assembly. Just make it so sturdy that no matter how hard you press it does not deflect in any way. Then make it a little stronger!

Your 'test' driver mentioned better stopping and less fade.

Better stopping. Can you lock all four wheels? If so, maybe he was talking about feel.

If can not lock all four, you need more brake torque. Do you drive this car on the street as well? Larger rotors or higher coeficient of friction pads.

With a single master cylinder put a adjustable proportioning valve back on the car so that you can adjust it from the cockpit. They do more than just cut down the rear pressure by a fixed amount. Rear brakes obviously.

Fade. Pad or fluid? Heck, could be both! Peddle get soft and spongy on you or does it stay high and firm just the car won't stop? The first is fluid the second, pad.

Ideally you would measure your pad and caliper/fluid temps and go from there. If it is the fluid, change to a high temp fluid, like wilwood 570 or better, bleed before EVERY event. If it is pad, determine the operating tempature range and CF of your current pads. Go to higher temp pad. More CF if you don't want to push as hard to stop at the same rate, less CF if you want to harder to stop at the same rate. If you have stock pads, or most of them for that matter and are unable to determine the CF for that pad then look at the edge codes, if they are still there!

If fade is still present, hopefully you tested the tempatures (both) that first time out and you will know where to go from there.

Cross drilled rotors or slotted rotors, aside from reducing mass which can INCREASE the heat of the rotor (talking small amounts here), do the same thing as having slots or groves in your pads. Much cheaper to put some in the pads! If bigger rotors are not needed, otherwise, why not, besides they look cool.

Check you pads for taper (leading edge thinner than the trailing) if that happens, post again, whole 'nother ball of wax!

You can go out and drop a bunch of money and still not be happy! Granted, if you are going to race it a lot, very, very few stock parts will be up to snuff. But you can get after market parts and have them still not do the trick.

Have fun!
