So what did you learn with tire pressures?

We're still experimenting so we haven't quite got it yet but basically keeping the rears higher than the fronts has helped with rotation a lot.

How are your AST's doing?

They're not.....ordered 1st week in Feb, still waiting

When I dropped my front pressures to anything below 37, i really crush that outside edge and that's when I corded my last set. I did have about 40 runs on them though, but I've kept my pressures up above 36 ever since in front...

Haven't tried the high rear pressure though...but having run on concrete for the first time in this car last week in Toledo, the car will need help rotating in Lincoln. There was NO rotation at all on the concrete...heck, only slightly recall any wheel spin so with the BIG grib on concrete, all the tail wagging under throttle disappeared, not much inside wheel spin...but also NO rotation
