Tire fitment question

Tires are Pirelli Corsa. My car is a 2002 S clad with 17 inch "Twist" rims.

What issues will I have? Will I have to replace the tires with 225/40 ZR 18 & 265/35 ZR 18/

Thanks

Front should fit fine as is. Rear 295 will not fit Boxster & you don't want them to unless you are building a drag racer. Rear wheels need a 15mm-25mm spacer. Depending on the "look" you want & tire size you get. 265/35 is best for handling & cost. A 285/30 is the biggest you can go but makes the car understeer.
