RWB are purely aesthetic. Originally it was cool because the vehicles were track rat 911's and the hack job they did on them were par for the course for track rat 911's.
Somewhere along the line they became an image thing, wealthy guys cutting up perfectly good cars to fit the narrative. If you ever see the process he does first hand you'll see that it's a hack job. I don't blame him, he's riding the wave until it's done but I don't have any respect for those cars. The look, I can dig the look, but the RWB name/fad I can't get on board with.
Sorry for the rant... To the original poster, you're doing a great job and keep it up. I always like to see design ideas that step out of the box even if it isn't for everybody. I have a 914 design I've been working on. My flare style is a bit closer to the GT flares than the RWB style flares, but I think it's in the same vein of classic but modern performance.
