Having owned a FFR which had a set of Cobra R mustang brakes in it, the wilwood SPF brakes feel...awesome
I did a couple hard braking tests yesterday and it feels like any other (pre ABS) sports car.
The FFR setup I had was far too strong up front- the fronts would lock and the rears would keep rolling. NOT confidence inspiring. Some owners took to installing the proportioning valve in the front circuit- apparently that worked out pretty well.
