I'm looking at a trackday at Goodwood and it has two categories; those with a maximum of 98dB, the other for 105dB. My preferred option (for reasons of costs and numbers on track at any time) would be the 98dB category, but don't know if I'd pass it.
Has anyone with an S4 had it tested for noise levels?
