Another vote for black
If your driving it properly whatever fancy colour you choose will only end up black anyway...
I was up close with Jamie Kips Suzuka Grey 8 Pots on his Stg2 TTRS using the same rotor and pads as Geordies yesterday, yes they looked a little mucky but literally 10 secs with the jetwash and they came back to being the same as fitting day. Jonny uses a protecting ceramic coating or some other mumbo jumbo stuff on all the stuff he sends out.
JK doesnt hang around either...
I also spilt OEM brake fluid all over JamS3s gallardo calipers on His TTRS and even being unwittingly left on for a couple of minutes theres wasnt any damage.
So there are options for protecting them, Jonny said this stuffs £100 a tin plus VAT.
Black or Lambo green doesnt matter to me John, reliable options there though...
Just doing a set Solar Orange for a TT owner tomorrow
