Tony, you understand Hella's car is anything but low-key hmm?
Hella, I'd go with those Corbeau seats myself.. Less chance of regretting it. Shape looks much more performance oriented, plus you know they might have actually had someone competent creating the shape.. Not just some designer worried about looks and cost-effectiveness.
Do try and get your bum in one of those anyways before you shed dough... Never know if there's something that doesn't "fit" right..
Good luck man, can't wait to see the finished product... your car's gonna be awesome.
