MKII Ttops (I'm selling these in a GB on the other board)
I didn't actually do the work on these, they were manufactured by Chaser Aero since they had to be EXACT to keep from leaking and wind noise. They are my connection when perfection or large quanities are required.

I'm just the middle man with these. All of my other stuff, I made my self though. Including the prototype ttops (went with 3 different designs before I said screw it and went professional)
