get to a bike shop. i bought a takachi or some shit for £50 for trackday use, as most cars i was in had a roof etc so didt feel the need for a mega expensive one.
i was also wearing it when i was hit off my old thundercat, t-boned a passat estate at about 45mph, using my face as a brake against the rear door/roof.
it done the job. was actually saving up for a £400 priced lid at the time lol
it makes you laugh when you see the likes of hadland peddling around in a 200mph+ esc cos wearing a 20 year old batterd lid lol
