Pilot Sport Cup vs Corsa
Discussion
Assuming I'm thinking of the same tyres as you (track day special type things, standard fit on CSLs), then I've been told the following about them (when fitted to a GT3) :
- Slightly more grip in the try, but you have to get good heat into them.
- Less grip in the wet.
- Not progressive compared to the corsas so trickier on the limit.
- More expensive.
If I've got the wrong tyres in mind, sorry

Here's a comparison test on a Porker:

We did extensive testing with the Michelin Pilot Sports as part of the M400's development. They're extremely well rated on other cars, such as the Porsche 996 (which Michelin brought along for back to back comparisons) but the Noble's chassis is particularly tyre-sensitive and they did not suit it nearly as well as the Pirellis. From what I can recall, the Michelins felt a lot 'softer' than the Corsas; the sidewalls flexed more under hard cornering; the steering felt vague and wooly; turn-in was less precise. Raising pressures improved matters (though not to the Corsas' standard), but then on-road ride suffered as a result. However, I was impressed with the sheer grip that they had, though this was only fractionally superior to the Corsas.
I know M400 owners are always looking for better (cheaper) alternatives to the Corsas, but after extensive testing I can assure you there is nothing better out there as a road/track compromise. Also bear in mind that the non-adjustable dampers and springs fitted to the M400 were designed to work at their best with the standard Pirellis.

Quite fair point. The Michelins series 3 and beyond were actually developed with heavy Porsche involvement. In a sense they were as much designed for the car as the inverse. No doubt also that the lower mass cars are best with the tyre they were tuned for. Normally I do not favor Pirelli as I have had an awful lot of sidewall failures on the Ferrari and Porsche but the Corsa does seem a different breed particularly its fit with the M400 IMHO.

Simon:
Did you test the Pilot Sport, the Pilot Sport PS2, or the Pilot Sport Cup? There are big differences between the first two, but a really huge difference between those two and the third. The first two are normal (though high performance) street tires, with comparatively soft sidewalls. The Pilot Sport Cup are supposed to have as stiff if not stiffer sidewalls than the Corsa.
I'm running the PS2's on my M400 right now as the One Lap of America requires street tires with a treadware rating of 140 or higher.
The corsas blow away the PS2's in my opinion. I think the PS2's win the battle in the wet but the corsas are wonderful in the dry. I'm still playing with air pressures but they are definitely higher than the corsas for the reason Simon stated, rollover.
Simon, do you have any old research on tire pressures you used with the PS2's?
