I am planning to do some recreational drag racing and not sure what tips you guys may have on where to buy helmet, jacket or any other beneficial items before racing at break neck speeds ?
No, they are usually good for 10 years before they require a more recent version...you should be good until 2025.
I'm a road track guy and use that brand.Cheaping out on a helmet makes zero sense. Buy a cheap helmet if you have a cheap head. Arai is the top of the heap in the motorcycle racing world. We would routinely hit our heads on the pavement and get up while wearing them. I would suspect they make an OK helmet for your purposes.
