i dont mean to rude but i think you really need to get the time slip because if you mist second and still run 131mph with a 2.8 i wouldnt worry about a harness yet you need a cage. what was your previous best.
hey col what where your 60ft time because if your running 131mph your 60s must be real bad (like 3)
i do 2.2 60ft and still manage to run 12.7 @ 110mph
cheers
