Philm has a good memory. Yep, Mr & Mrs Flatchat(Yve & Chris) have used them, along with just about every other brand out there. Not sure of what they thought of them though.
Hey, I'm going to run Michelin Pilot Sport(road version) on the GT40.
Richard, you can't go past new Toyo Proxies R888. Perfectly suited to the type of racing we do and best bang for buck. That's what my brother runs on the black Harrison. Significantly better than the old Proxies, which I think are now out of production.
