One thing I learned quickly with the Mickeys is you don't need a lot of smoke in the water to get them right. I've also run up to 27 psi in the slicks. I keep pumping them until they spin to get a handle on the track condidtions. Higher pressure, less rolling resistance, better MPH.
BTW, I did replace the spring eye bushings with Urethane. Made the 60' much more consistent. Well, that and the True-Trac differential from Detroit Locker.
