Enkei Aegis rim specifications are here. I can't remember how much I payed for them...sorry Might want to call Ben at Wheels Boutique for the latest prices.
I previously had 18x8.5 (f) w/215-35 and 19x9.5 (r) w/265-30 and the front rim was too small for the tire. I am presently running J-line rims. I still have the Enkei wheels. Here is a pic of them on my car before I did the widebody with a 25mm spacer in the rear.
