Patience my friend, all shall be revealed next week ;) Thanks for the words of advice fellas! Looks like it has it's advantages but it's not a cost I can justify at the moment. Also I do like the ability as Asad said to change pressure whenever I like eg for economy runs on motorway, normal use and track use. Also I did actually notice the grip was a lot better after they were worn in, something that wasn't as apparent with the T1Rs probably as they're a softer compound? There's been quite a bit of progress with the car and it should be on track for a big update next week, with big thanks to
