I've had bad experience of using SC4 or the no marking "road" supercorsa -I just couldn't get any heat into them at all and lowsided at Brands.
When I got back to the paddock the tyres showed virtually no wear (not warming up) at all, and I was on a pretty quick pace for a 6 or so laps.
So for me, I'll not use anything less than SC2 rear and SC1 front (only use SC1 front as it wears out half as quick as the rear so they can then be swapped at the same time).
Maybe its psychological, maybe it was an old SC4 - who knows, but for me, I'll not touch them.
