Ditto what Flavor 987S said.
I put a set of 19" Carrera Classics (8" wide fronts, 10" wide rears) on my 2001 'S' with the same size Michelin PS2s. I also changed out my suspension to the RoW M030 suspension package (struts, springs and sway bars). No issues with brake caliper, strut or body clearance, and the ride is very nice. Car sticks to the road and handling is sharp and predictable. Wheels and tires fill out the wheel wells nicely too.
