285 puts you in my bracket. although at 112kgs plus kit I won a race or two in B last year, Tbh A class means you don't have to try so hard
Either way,mistreat fun and whether front back or the middle you'll have a race with someone
Check out the race from brands which was televised via motors tv, think someone may have linked it to YouTube if you do a search
Feel free to pop along for a chat: pretty friendly place
