I went to a small motorbike accessories ship in Stevenage near our Hitchin first. The Italian guy there seemed to know everything & felt I need to spend 300+ on something that wasn't what I wanted or needed. I do maybe 1 or 2 days a year I might need a lid.
I thought my initial budget would be 100 quid but was happy to pay 150 for this one to get a carbon lid that fitted well, was comfortable, from a decent known branded & well respected manufacturer. Also it had a nice bag to keep it nice as well that sealed the deal.
What track day you doing?
I just signed up for a Rye House karting driver development evening on 25th Sept. They also do a monthly championship thing I might look at as Rye House is only 20 odd mins away from me.
