When I ran mine this past weekend, it was unpredictably snap sideways loose. Sometimes early in the turn, sometimes in the middle, sometimes late. Was dependent on how much weight transfer you had in the car, how much wheel, and how hard you were on the gas.
No matter what changes I did to the rear, it didn't help fix it. Car felt different, but center off it wasn't an improvement. Next time I go back to the track, I'm putting the baseline rear back on and try changing only the front.
