These rims are on tirerack.com for 229 for 18x8's and 249 for 18x9's. I think they look good, but for 229-249? Should i be cautious about buying these, and more importantly, if i put 2 18x8's up front and 2 18x9's in the rear, will it mess up my handling noticeably? Or should i just put 18x9's all the way around? Tell me what you guys think. Late
