First, I have to say that the handing with the pro touring bar is great. I was going into and coming out of corners 10 mph faster than with the Herb Adams bar I'd had in the car for 10 years, mostly because the suspension was absorbing the bumps instead of hopping over them.
but... after easily averaging 148 mph for 30 miles and backing off to cruise at 120 mph to get my average speed back to 135, the car started filling with smoke, coming from the back of the car.
It turns out that the Huge Herb Adams rear swaybar we had also helped triangulate the LCA's and locate the rear axle laterally... and the axle shifted 1.5" to the right, destroying the outside of one tire on the fender and melting the inside of the other tire against the frame. It looks like one of the adjustable uppers may have loosed up, but they were just tightened a month ago.
I'm beginning to think Adjustable uppers are pretty stupid on a car that is driven more than a 1/4 mile at a time and they are going to get pinned.
So it turns out, if you install the PT rear bar, unless you put in a panhard bad or a fayes2 watts link DON'T put in Spherical LCA/UCA joints and especially spherical adjustable uppers, unless you are running 215 wide tires.
Who'd have thought binding was good?
