2.1 60 foot is extremely optimistic for any track.
2.2X is great.
2.3X is good.
2.4X is normal
I've only seen 2 slips/cars with 2.0X 60' times.
One had drag slicks and a Quaife.
The other was Brad's SE with the torque strap and a few other tricks.
How did you launch?
RPM level? Tire spin? Clutch slip?
High tires pressures are good.
36 in front and 40 in back is what I run at the track. You don't want to go too high in the front or you start to lose contact patch.
