I just bought a really nice set of used cobra 2000's for 375 with 275/35/18 tires, can't beat the price. As far as filling in the wheel wells, if you go with that size, it really doesn't fill anything in because the height of 245/45/17 is almost equal to the 275/35/18 height, they do look much better though. you can compare these pix to my pix in the previous post.

 

Drop looks good.. Not too high, not too low. Nice

 

its weird cuz im only dropped on ebay springs and stock shocks lol and im redic dumped i know its not good for the shocks but im gonna get a nicer suspension later on, for now im just messing around.
