I have raced with Ast and had it on my track car and i am not a big fan of it. It doesn t inspire me that a company like Ast owns moton. I have raced with moton a lot it was a great shock when the company was on their own. But after it went bankrupt and got sold to AST we changed to JRZ and with big succes.
We use JRZ triple adjustment shocks on the race BMW GT4 and i use JRZ RS1 on my 1M coupe trackday car.
I hope moton stays moton within Ast but i also heard rumors that they are putting ast internals in moton shocks. Lets hope not!
Everybody has their favourite but for me it's JRZ and the moton bevor bankrupsy. Moton and JRZ were in the base setup almost the same.
I wish ast/moton all the best and hope they can keep the moton quality alive.
