I'm not sure where you saw this picture but if it was a White RS and it looked like it had a white brake light on the spoiler than that was probably Jame's car. He put some kind of decal/sticker thing on his lights. they are actually white lines. pretty unique looking. :checkit:
Yeah, my brake lights all high white pinstripe decals across them - makes them look whited out from a distance. I think the main site (www.RS25.com) has a few shots at the top as your browse the pages - go check.
