hey guys.. have a friend of mine coming to America with a nasty turbo 9R to run loring and he wasn't sure if his valvestem meets the spec.. honestly, neither do i.. tried getting a hold of todd dross, but to no avail as he's a busy man.
heres what he sent me.. any help will be greatly appreciated.I'm ask a question on the valve stems ? My goal is 200 MPH. I have aluminium caps with stock valve and the rule is :
7.B.9 Valve Stems and Caps:
All tire valve stems must be fitted with metal valve caps. Over 175 MPH, tubeless tires must use metal valve stems. Tube type tires with rubber valve stems that are angled relative to the rotational plane of the wheel must have those valve stems secured to resist centrifugal force deflection. Safety wire or other approved restraining device is required.
My stock rubber valves with aluminium caps are good or not
