Enkei PW10's | 18x8, 50 offset, 5x114.3 lug, 72.6 bore
 

From what I can tell browsing and searching this forum, these should fit my 2010 RX8 Sport:

18x8 Enkei PW10 Gunmetal Machine Offset(50) Lug(5x114.3) Bore(72.6) Part Number(500-880-6550GMM)

Is this correct?

I was having new tires put on (Bridgestone DriveGuards) and they told me three out of four of my wheels are bent. So I guess that means I have a good reason for new wheels.

I thought those ones looked pretty awesome. I can get 0% APR for 12 months through Amazon. Four of them would ship for a total of $750 which isn't bad IMO.

Yes, that is exactly the same size and offset as the stock wheels.
