That's ok, but you could still have some binding in the chassis, dirty him joints (I'm guessing because I don't know your chassis or set up) or even a bent shock. I've seen a bent shock drive a guy to almost quit racing.
He kept bitching that the car was untuneable because tuning the rear shocks did nothing. I told him to send the shocks back to Afco and have them revalved. Come to find out on shock had a bent shaft. After the shock repair the car had very good tuning characteristics and the owner was no longer ready to quit.
Just something to think about. I'm not a big fan of 60 foot times but I'm a stick guy. You can miss a lot in 60 feet.
