How low is the car - stock front suspension - stock rear wheel wells - what brakes? If everything is near stock and the car is lowered about 2 - 3 inches this will get you started. Fronts 18x8 with 4.75 backspace and a 245/40-18 tire. Rear 19x9.5 with a 5.5 backspace and a 275/40-19 tire. There are many combinations that will work and each car is a little different. 19x9.5 may be tough to find so you can drop down to a 9 wide. If you jump up to 10 it gets very tough to get it in there without rubbing. Do a search on 10s and you will see what I mean. Some pounding on the inner well and some trimming on the outter lip and it's still tight. You can also drop down to 35 series tires if you like. Good luck!
