I'm thinking of using P Zero Corsa Systems (N rated for Porsches) in 255/35-19 and 345/35/-19's and since they were the OEM tires on the 360CS and 996GT3RS, they should be able to handle the top speed requirements of the GT and I had these and the regular P Zero Corsa's (non N rated because they aren't as good in the wet but stickier in the dry but no longer available) on my 996GT3 before, both sets stick very well and were quite good track tires that can be driven on the road. If more poeple are interested in getting these and the Dymags, maybe we should start a separate thread for a group buy. Sorry for hijacking this thread.
