I prefer Perellis
Super Corsas are great especially when cut so the grooves extend to the edge, Diablos are excellent, just got another set yesterday, also got a set of Diablo Corsas but haven't tried them yet.
Also happy with Metzelers the Rennsports are great on the track, I have recently been using Sportecs on the 916 including the Cadwell trackday where they did a excellent job.
Dunlop D207RRs again are a good tyre as is the D207GP but these need to be warmed up before pushed.

Dave..... go for diablo corsas mate..... best tyres i've ever fitted.:cool:

Went to Mark at RideinTyres in Reading on Saturday and went for the Diablo Corsas in the end.

First impressions..................excellent :smug:

Went over to OnYerBike yesterday for the oil cooler check on the recall and scrubbed them in a bit over about 100 miles. Just need to get rid of the chicken strips now :lol:

Out of interest........what are peeps paying for these (190 rear) ............. loose wheels?

Right. After 3k miles, my 999S needs a new back tyre. The OE was Michelin Sport Cups, with a 190/50 at the back. I am opting for a 180/55 to replace it and will report back with my findings concerning moving down from a 190 to a 180.
I still have a lot of wear left on the front tyre, so I'm staying with Mich for now (as I've no complaints) but I reckon I will replace front and back with Bridgestone BT014s next time, to see how they compare.

Decisions, decisions. Wish I had a rodent to advise me, like Jools has. :lol:
