wat is the correct offset for a 17" wheel and for a 18" wheel to fit a my 94 WRX, and wat tyre size should i use, so many people use different sizes

Hi,

Some people have used a 45 to 48mm offset and found when lowering the car the wheels rub on the arches, however if you stay with the oe offset which is between 50 and 53mm you won't have a problem if you decide to lower the car. I have my01 wheels (53mm offset) on my 95 wrx and pi springs, no problems.
