I spent Saturday at Castle Combe and as the day progressed and the track dried out pads that had been fine at lower speed tracks like Llandow rapidly started to go off, I'm going to keep the M1144s for road use, but need a recommendation as to the next step, M1155s are the obvious choice but want to know what the racers amongst you use.

Car weighs about 650kg wet Inc driver, disks are 260mm solid with Powerlite calipers.

Thanks

I find 1144s great on an open-wheeled 700 kg car with 280mm vented discs - I would consider going to vented discs or adding some air ducting as a possible alternative?

Our friend Tim Gray, multiple RGB and Locost Champion, told us to fit POLYMATRIX E pads to the Phoenix. Lots of the RGB guys use them. I probably don't drive the car hard enough to properly test them out but they seem OK. Consistent feel, no fade.
