Those prices aren't bad at all. Just to give you an idea of cost of wheels, our old GT3, we purchased every part to convert it over to an RS. The wheels from Porsche were $2400 for the fronts, and $3600 for the rears! Thats a total of $6000.
The wheels on our GT3R racecar are BBS Centerlock Forged Magnesiums. We tore up two on an off road excursion, costing a mere $2100/each. Michael Shumachers F1 BBS wheels cost Ferrari over $4k each.

PS: MachSpeed if you get a chance, PM me total prices for a set for an Elise (4X100, ET40 I believe), and a price for a set for possible a VW Beetle RSi. I have no clue the offset, I just know we were running the VW Racing 18X9 wheels all around with a crazy amount of offset.
