I use Wilwood 6 pistons in the front, 4 pistons in the back. Along with a CNC dual manual MC, and a manual pedal. Excellent braking power. Car will almost stand on it's nose.

Your MC is fine. Are you using a power brake pedal, or manual brake? The manual is a little longer, and gives better force appliction into the MC.

What pads are you using? Some pads are designed mostly for track use, and have to be warm to work well. Others - like the BP-10 - work well at much lower street temps. On that same note, do you have cooling ducts?

When you switch the rears to disc, you'll need to change the MC to match. You might consider the CNC part. Mike Forte has also grafted a booster to the CNC MC for people who insist on PB; but I don't really see the need for it.
