I could buy an almost new set of 19" 997S rims sizing 8*19J ET57 (front) and 11*19J ET67 (rear) fitted with 235/35 (front) and 295/30 (rear) tires. Can I fit these on my 996 C2? If so, are any spacers required??

Porsche went to a different overall tire diameter with the 987 and 997. 986/996 used tires with overall diameter from 25.5-26. The newer tires are over 26.5. Depending on the numbers that you use this is 2-4% bigger. Porsche states the 4% is the allowable difference from stock sizes for ABS and PSM. The new tires are at the upper limit. The larger tires will also effect acceleration. Cosmetically the larger tires will fill out the wheel wells.

What are the wheel sizes and offsets for the stock 996 wheels? If you have those numbers you can calculate the offsets required for 8's and 11's.

Perusing some of the tire size charts it seems that 986/996 tires sizes tend to be in the low 25's. 26.5 is getting pretty big.
