118 mile, legal highway race through west texas.

 

looks very cool. i was reading the rules and it looks like a stock 8 would need some safety upgrades (mounted fire ext. 5 or 6 point safety harness). It looks like your classified by speed? But i was seeing fast cars in the lower speed brackets. im not a race guy so if someone could explain this that would be great. if i just had to mount a fire ext. i would do this
