Wheel fitment question?
 

Someone has for sale off their 2002 Boxster S the following wheel sizes

front: 7.5 x 18, offset 50mm (part no. 99336213406)
rear: 10 x 18, 55mm offest (part no. 99336213801)

Is this a correct size, and will spacers be required? Thanks.

They should just bolt right on

i noticed that your fronts are 7.5..the extra width makes no difference? thanks..

My fronts are 8.5"...But it wont make a difference in your case. Only real difference is my wheel can support a wider tire. Regardless i still run the reccommended 225/40/18...

thanks..can someone explain what offset means? and the need for spacers when needed?
