Well I think I've got my pad problem solved with PFC97 up ront and 01 in back. Looking for new tires both stereet and buying wheels for track. Can I increase the 996 turbo tires from 225 to 235/40 -18 on stock hollow spoke wheeels (8") and how about rears; stay with the 295/30 -18 or move to larger 315/30 -18 on the 11" hollow spokes?

Any thoughts? Not as concerned about street tires (running SO2-A's) but would like to increase size up front for track (Michelin pilot sport cups). Possible, any problems on fit or handling?

 

the larger tires will be fine.

 

As Tom says...no problem with 235/40 and 315/30...18's.
