You know, it would be nice if you could post up some pics of these cars. I'm not trying to be a jerk, but generally, people don't like looking things up for other people.
I don't like body kits on the RX-8. If I had to choose, it would be the Mazdaspeed, because the Veilside is a little.. too out there
Plus Mazdaspeed kicks a lot of ass.
If you really had all that money to blow, go RE Amemiya.
