Re: 1/8 mile time
Love DRs but, they need alot of burnout to get hot and they take alot of passes before they settle in. Doing the three pedal tap dance in the burnout box isn't ton of fun. I hold the brake, roll my right foot over onto gas and drop the clutch in second gear. Having a line lock makes embarrassing chug outs less likely, though.
I have a set of old 255/16 DRs and, I'm going to slap them on some old stang wheels and see if they'l help next season on this new car. Tough to imagine them hurting, compared to the rock hard sidewall Pirelli P Zero 19s.
