Well, I had to wait for you to comment. You are our sponsor, after all.
Right - here's the bottom line. Braking is MUCH improved.
There's a lot more feel in the pedal to my mind - you know how much braking effort is going in from the position of the pedal, not the muscles on your leg bulging under the strain.
You also get the feel that the car is going to stop in time, none of that "pray and press harder" when you have to anchor up rapidly. Initial bite is much more in line with my daily drivers.
In fact in a drag test on an empty road, I managed to lock the wheels by standing on the brakes - something I have never seen outside the IVA station...
So - I declare it a complete success. Gentlemen, start your credit cards!
