FRPP C-Springs...

Well after spending so much money on performance, I've decided to finally get some lowering springs. I wanted to get the H and R Super Sports but I dont like things I've heard about how much they suck at the track. I've only heard good things about FRPP C-springs, and they seem to give the car the stance I'm looking for. Are they ok at the track as far as launching goes?? And will I need c/c plates with these springs?? Oh and if there are any pics of C-springs on new edges, please post em'.
