I dont know if you can get other spring rates for you coilovers, but try lower spring rates. I had 7/5 on my previous JICs and they were the most comfortable street coils I've ever driven/riden(compared to stance, megan, KTS, Tein HEs) . And they were great for autocrossing, the dampening adjustability was well matched with the spring rate. But they were a bit soft for me for drifting. But then its all driver's preference.
