I've been looking at trackdays and see they all seem to have a 105 db noise limit.
If so how the smeg do I know if my zorst is less than that before I pay me hard earned wedge?
I was looking at Croft, Oulton park and Rockingham. All have the 105 db restriction.
Mind you I see others have a 98db limit!
