Welcome, very nice ride.

It is clamed that C5 brakes work better than C4 brakes because of the C5's increased pad area. IMHO it is because the C5 calipers have a larger piston diameter of
1.62" compared to the C4's 1.5". C5 calipers = a change in the front hydraulic ratio that provides more pad pressure for a given pedal pressure. You can acheive similar results using an eariler year master cylinder with a smaller bore size. Your master cyl = 15/16". 88-91 master cylinder 7/8". While the master cylinder is off the vehicle suggest a DRM brake bias spring be installed it will improve rear brake performance.

If you require statistical data on the hydraulic ratio changes I'll pull it off my shop computer.

No statistical data required on my end. Good advise. The previous owner already tracked the car and has very good brake pads on there. They are amazingly noisy and they will coat my wheels with brake dust extremely quickly. The car does stop well, but I have not been able to track it yet. I will be putting the slotted rotors on for sure because the rotors need to be replaced badly.
