tp-996 you might want to have your re-preload backed off a bit.

The reason I change Supercorsas/Rennesports etc is because they start to slide around and are coming to the end of their maximum grip level, this is so for most racers.

If you are buying part worns and using them on track days and not having any problems with grip then you would be better of using a sport compound road tyre.

You dont need the expense of tyre warmers and if a session is damp you dont need to change to wets or inters etc. as most road tyres are designed to cope with varied conditions
