those Those are just beeeeeeeeeeeeeeeeeeeeeyooooooooooooooooootiful!
Wish I'd known about these before I had my PCCB's replaced with the Alcon's (which, I believe add 10lbs per corner
)

Also are you running 19" rims cos the websites say the 380mm fronts only fits 19s?
Thanks

Brembo supplies the GTR kit with the 380 mm fronts and 328 mm rears.
You can run it on 18 " rims provided you have proper clearance (custom rims or I have been told that the Gt2 rims will clear them). I added a 5mm spacer for the front wheels just for some extra clearance too.

Still no comment as to whether these maintain the ebrake/handbrake.

I am concerned with the very tight clearances between wheel rim and calliper (see photo, 18 inch wheels). Suppose, for example, road debris - a stone - enter the space between spokes and disk. There's no place for it to escape. Eventually it could wedge itself at the narowest point, between the wheel rim and the top of the calliper. What then?
To date, the largest available factory or after-market brakes for 18 inch wheels are 350-355 and offer plenty of clearance. Is safety an issue with 380s?
