My gramlight 57pro's 18x9 only 2.5" lip?

[cr00k_lyn]

I ordered a set of gramlight 57 pro's for my rps13

f:17x8 r:18x9

I got a call today that the rear wheels came in today and the guy told me the lip is only 2.5" and only way to get a bigger lip with out custom order is to go with 17's and it would be a 3.5-4" lip.

Now my questions and concern is that a 2.5" lip in the back would look horrible. ne opinions or pics of how a 2.5" would look in the back?

Need to make a decision.

thanks
