If any of yous are considering getting into MSA motorsport, here's a good deal on Arai GP-6S helmets, 100£ off the list price, free courier. They are Snell 2010 / FIA approved. The helmets are brand new, never worn, in original boxes with all paperwork and stuff.
I have one L size ( 59-60cm ) and one M size ( 58-58cm ) atm but can take orders for other sizes with reasonably quick delivery.
