What would be the optimal tyre width for performance? My car is a classic wagon and I will be fitting wide arches (a few of the lads are running 255s with similar bits of bolted on plastic). In addition I will try some Federal RSR track tyres too and the wheels I choose will be 17". My shocks and springs are off a P1 with Paranoid Fabrication saggy *** spacers for the rear. 22mm ARBs F&R, maybe go to 24mm rear as the relative delta between the spring rates front to rear is slightly higher for the P1 setup compared with standard WRX wagon.

Would 255 section (at a suitably low pressure) and semi slick tyres be too grippy?? i.e. "huge" grip which suddenly falls off a cliff. Would 235 width tyres with something like 15 to 30mm spacers be a kinder option in terms of transition from grip to slip? They would also be lighter and perhaps be a little cleaner in terms of handling, feedback and adjustability?
The car is not a daily driver as i'm never bloody well home and will be used for track days when I can, big skids in a forest if i'm feeling foolish but mainly proper fast road (think A93 through Glen Shee hence P1 suspension rather then stiff coilovers).
