Took the Rocco out for a late night drive around some of my local twisties, every point I came to call on them, they inspired confidence, scrubbing huge speed off in very short distances.
Found a REALLY long private road tonight and got up to 120... slammed on the brakes to dead stop... short pedal but still able to be modulated progressively... It hauled ass and my mate who was in the car was giggling like a child.
I then did several 90ish to 30, stops almost immediately after, one after the other over the course of about 2 or 3 roundabouts within one mile of each other and then a final 80 to nothing stop and while I got a hideous smell of brakes there was no discernable fade.
Wheels are now caked in dust though, will have to clean them up tomorrow. Iron X would be funny to try.
I do notice the rear end gets a bit... um... floaty. But that's because the entire weight of the vehicle is going forwards... basic physics, a rear brake upgrade wouldn't go a miss... but more for looks really. You will balance it out a little bit, at least the rear upgrade is nice and cheap
