Tem I would just keep driving what you have as it looked to me that you are behind on your inputs.
You will get this as you drive more, but you can drive the car closer to the edge of traction if you concentrate at getting the whole car rotated before the cones. It looked to me like you are turning the steering wheel at or just before the cones.
I am no pro auto-xer for sure, but on my ASP set up I used 295mm C71 Hankook Ventus TD on 11 wide rim F/R and 11k F/R Ohlins (more streetable than my old stock springs/GABs, its not the spring rate but damping that kills ride quality IMO).
I had to really step the damping up on the Ohlins with these tires to control body movement and they are not as sticky as Hoosiers, so I would recommend more spring- like 14K for wide Hoosiers.
I wouldn't go too low unless you also correct at least the front roll center otherwise you are increasing the roll couple and will actually have more body roll than if you were at a reasonable height.
Also, my preference is a little taller car with a little softer springs (I'm not talking anything like stock- just relative terms) versus a really low car with very stiff springs to keep it from bottoming the suspension. A really stiff car gets pretty skatey and unforgiving.
