Racetech sells shock springs. Eibach, Hyperco, others make springs, too. The racetech springs are probably Eibachs anyway. Racetech claims you need their screw adjusting collar to fit the spring on the stock damper, which I think is just a way to make you buy that adjuster. That would be handy, but of course is more money.
I have a donor 2004 R6 spring on mine, it's about a 9.8 kg/mm (stock is about 8.6) and works much better for me, although the damping still ain't right.
edited, I had the spring rates wrong....
