As another interesting and pertinent side note, (that some do not know or consider in their builds), be aware that the Wilwood MC's are specifically designed to provide a 75/25 output (75% to the front, but only 25% to the rear). By direct comparison, the factory C3 MC's are designed to provide approximately a 65/35 (65% to the front and a larger output of 35%+ to the rear). You have been mentioning that your front brakes are behaving, but can't quite get your rear brakes to bite down properly. Soooo.... The output difference between the Wilwood MC and the C3 Vette MC's are indeed different - the C3 MC's put out more volume to the rear brakes by design (it's the location of the comp ports inside the fluid wells of the MC fluid bowls that makes the difference).
