996 Turbo Rear Diffuser?

What are the options out there for a diffuser for the 996 turbo's rear bumper?

I know vivid makes a nice looking one. Any other options?

heavychevy I think you are referring to. He had to convert exhaust to center outlet for his design

Yeah, we made one, but it's homemade from alumalite. Anything functional will require exhaust mods because you can't get enough upward angle on it. I still think mine needs more angle actually, and some curvature. If you are looking for cosmetic, there aren't many options at all.

Nothing straight bolt on. I'm using this one to make a setup for mine. Have to add a 997 rear undertray piece along with an aluminum adapter, make Some brackets, etc. Will mine add a lot of downforce, probabaly not, I'm more on the reduction of drag by the rear bumper.

Could you just extend it out from the back farther to fit the additional curve and angle? Even though the new 911RSR is mid engine that diffuser is hanging out there pretty far, must work. I don't think NASA rules on how far the diffuser sticks out in TT1/ST1 Click image for larger version
