Almost every 848 that has had even a minor low side on the right, will have a damaged wet clutch cover... I'm sure I can speak for others and say there would be great target market. The cost of a new OEM cover is over 500 dollars.. so if it were half that, I'd be all over it.
Rearsets would be good as well. If the quality of any of the products you are mentioning is like the levers I got from motowheels, I'll definitely buy.
