I've found TC ones are good for about 10 big (3 digits to standstill) stops in very quick succession before they have faded to the point of really struggling to pull the car up. I'd say you'd be hard pushed to manage that on UK roads, outside of cities towns made up of nothing but roundabouts on dual carriageways...
Just goes to show how big an effect driving style has. I would probably get bored after the first roundabout and go into constant 50MPH mode on both the roundabouts and dual carriageways thereafter.
I tend to start scraping the door handles when I get on a twisty road but I find they don't really punish the brakes (unless you put them on the side of a mountain - not available in Hampshire).
TBH, having an auto box increasingly tends to discourage me from playing in the Omega.
I haven't had a GM brake disk go wobbly on me yet.
I can't be bothered with the wear sensors either. I find the pedal goes pretty wooden once they're down to a few mm so they get replaced then anyway.
