There is TONS you can do to a 991 as you have seen - but this one has turned into a Purist's dream, using OEM+ goodies all over, on this 2013 991 C2S. The car was lowered down on the TechArt Springs which brings it down about 15-25mm depending on if you have PASM or not. We also fitted a OEM SSK to the factory 7-speed transmission, and added the GIAC Software Upgrade which added a nice amount of low end torque the 991's need. We then moved on to the exhaust and fitted an Akrapovic System, and to keep the car planted a bit better on the track, the client opted for the 245/35/20 and 305/30/20 Trofeo R tire with H&R 10mm Spacers up front and 15mm Spacers in the rear to make the fitment perfectly flush!

Here is the complete list of Modifications:

So these are basically a competitor for the Michelin Pilot Sport Cup 2. They are a much more track oriented tire but stick quite a bit better. We have mounted them on counltess GT3's and our clients seem to be very happy with them. They are even made in the same factory as Pirelli's Formula1 Tires in Turkey!
