Yeah japfest at coombe has sold out pretty quick this year - similar to like it did last year has to be early. Luckily ive bought some just after it went on sale,and you can always pick some up on the day - just got to ask around. My only concern with the open pitlane at JF2 is that you are going to have a lot of mixed abilities on track, up to 40 cars, and some people with no idea to call it time after 20mins when they start to suffer brake fade and as a result casue an accident! As for sound checks, coombe is pretty strict at 100db static - however they dont have any drive by checks. Where as at donnington its 100db static and 98db on drive by - those with screamers usually get pulled off The drive by is usually on the pit wall somewhere, and with majority of screamers pointing this direction, youll be getting black flagged so you will either need to lift off and cruise, or look into modding the screamer to queiten it down - ie have it pointing out towards the drivers side/plumbed back into exhaust should help
