My subjective opinion is that the braking has improved in the neighborhood of 15% to 20%. I have no test data to support it, just my feeling.
And I only have the fronts. I'm really looking forward to getting the rears done too. I know the rears won't make nearly as much difference, but it will sure look better to have something that isn't as wimpy looking as the stock rears.
I don't think people fully understand how adding brake power really compliments any car. I know in my SHO, doing the 96 brake up grade, it was the best money I spent on the car. I'm sure the same is for these cars.
