I have mine set exactly the way you guys do. My first event was cold and dusty so it is tough to use as a bench mark, but the car still tended to under steer, but far less than last year. I could get the car to rotate, still not a mini though . My tire pressures were very similar. One other note the tires had about 100 miles on them. Next event hoping for warmer and cleaner.
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...

Reduced the pressure in my rear tires this weekend at the event and the car was great....going to hold off on softening the settings until I get a few more events in. But I immediately dropped 1 second...and if I did not cone away my fastest time would have been much higher in the standings. That aside, I felt much more confident in the car and have a good feeling about where it can be. So still happy with the Konis
Alan...what pressures are you running?
That is close to what I used to run....at the last even I tried to run 38F 35 R and immediately picked up over .5 seconds. It did not feel like I wanted it to, but it was definitely a bit quicker for me. When I ran it 38 45 after the Konis were installed it was a bit nervous in the slaloms. I am going to try the new pressures again this weekend and see if I still see good results.
