Pagid make uprated brake pads for high performance and motorsport purposes. Quite a few in 997 Register and elsewhere who like spirited driving use them and rate them highly. Michelin Pilot Super Sport are the way to go, but these are not currently 'N' rated for Porsches, although some people have already fitted them when they are unconcerned about warranty etc. If you need some urgently and an 'N' rated tyre is required, there is a choice of Pirelli, Michelin Pilot Sport, Continental or Bridgestone. However, tyres in the correct Porsche sizes currently seem in short supply, so it may be Hobson's choice as to which make is available. Regards, Clive.
