As long as the front are the same and the rear are the same your okay. Now if you had right to left different the weight of the rim and tire would throw off you car since its front wheel drive.
Why not do everything different. 15" rim and 16" rim on the front,
17" and 18" on the rear. All in different color, manufacturer, style, and put different tires on each rim. That way you'll be street racing ready, daily driver ready, show ready, and bling bling ready all at the same time. :thumbup:
