Well I am doing my best for Sean and SPL. I am driving the **** out of the arms and they are working as advertised. It did kind of piss me off that after I did a test or two or three I had to ship them off (take them off the Nismo) to the "professional drivers" and then it turns out they didn't test the new versions. As far as I am concerned, I am the best gauge of anyone on these arms. I might not be a race team but I am definitely a hard core track weekend warrior!!!!!!!
