Unexpected poor handling with Konis

I ran my first event of the season yesterday with my newly-installed Konis and the results were poor. I'm now trying to figure out what to do next.

Setup: 2014 ST with Dirizza ZII 225/45-16 on OZ wheels. Porterfield R4S brake pads. Koni yellows front and rear.

1st run: Shocks full stiff rear, 1/2 turn from soft front. 38 psi front/42 rear.

Car was all over the place, I could not keep the rear end planted. All I can do to make it through the course with just one cone. 3 seconds behind Des in his ST.

2nd run: Shocks the same, pressures 38/38.

Much better to begin with but still eager to rotate. Entered a fast three-cone slalom with a short braking area into a right-hander. Car snap spun on me and sent me off course into the grass and a side taxiway. Day over per our 4-wheels-off rule with a DSQ on the score sheet.

From my perspective the common wisdom of Koni shock settings is way off. I'm thinking the middle setting rear and half-way to 3/4 front. Am I right and everyone else is wrong or did we goof up our install some way?

Des does have a Cobb front bar but that doesn't explain the 4 second difference between us. I road with Des and his car had very good turn-in but tended to loose grip in hard sweepers. My goal is the best of both worlds, high grip with good turn-in. I think it's doable, it's just figuring out how...

I am about a 1/4 turn off of full stiff in the rear and about a half turn off of full soft in the front. I was going to turn them to full soft before the novice school this weekend so I can see how it acts on the asphalt that we normally drive on. But I didn't notice anything odd with the handling of the Koni Yellows. They improved the car feel and direction when on course, even though my time was off pace.

The car did push a little bit this weekend like Trevor mentioned in his car, but I still got it to rotate as I think the push I felt was my poor driving and going too hot into the corners. That being said I am on the Hawk Street/Race rotor destroyers and they have really good initial bite, which REALLY through me off on the first application.
