Just got this in the mail a couple days ago from Cosmic quads,
http://www.cosmicquads.com they do extremely nice work very reasonable cost wise too. I gave them an idea of what I wanted, a standard seat in black with the foam cut down and a target stenciled onto the back of it and they did it picture perfect. I sit much lower now then I did before, and I think it'll help the cornering a ton on the drier tracks. Can't wait to try it out at the next race.
