Boxster S on to GT3 Steel Brakes

[Marc_Hill]

I have the standard PCCB on my 981 Boxster S. If I was considering putting steels on, would it be possible to fit 380x34mm and 380x30mm GT3 discs without too much hassle?

I know my standard discs are 350x34mm and 350x28mm, but pretty sure the callipers are the same.

They weigh loads, 350mm steels will be fine, look at the 981 Spyder for part numbers.

or you can buy the girodisk PCCB replacements.
