Hey i was wondering, i was looking to buy AFS 2003 cobra 18 x 9 in the front and thinking about the 18 x 10.5 rims in the rear for my 2003 cobra. Im looking to get the bf goodrich g-force tdw t/a 2 tires but im not really sure what the best size would be? Do i need spacers for the rear? i've heard that if you go with an 18 inch rim you dont need to. Also, i was thinking about lowering my cobra with eibach lowering springs pro kit some time afterwards, would this affect my choice at all?
