Thanks man!
I believe that from now on dual clutch is the way to go.
DSG has proved reliable over the years, cand wait to get the conversion done. I've tried 2 single-mass clutches, both of them seems to have trouble with fast shifting at high rpm. it felt like forcing the car into gear, and after 2 laps the clutch was so hot that it would not go into gear over 6500 rpm.
My problem now is that Mihnea R Cotet from MRC tried to connect to the gearbox and it didn't respond. He told me that is not 100% dead we will need to try again with another DSG connector, but I'm already looking for alternatives if the mechatronic is dead.
About AST 5300 I've read only good things, I really hope it will be an upgrade from PSS10. The front spring is 100Nm and the rear 120Nm. I really liked the high speed rebound adjust ability, I think it will make the difference over the kerbs. Also one of the deciding points was the rear coilover setup, it is always good to have the springs as close to the exterior as possible.
Can't wait to test it on the track. ;)
