I'm in the market for a set of race springs for autocrossing, I've ridden in a friend's S2000 and know I could handle their rates.
I'd like to know the stock spring rates for a S2000, preferably in lb/in.
Thanks,
Jonathan

 

I think non standard springs will take you out of the stock autox classes.

According to King the spring rates are 3.9/5.2 in kg/mm.. convert if you must.

 

thanks for the info,
right now with my modifications, I'm going to have to race in E-prepared, or in street with street tire, so I thought I'd go ahead and get any advantage I could

I have HKS springs with 5.1 kg/mm (280 lb/ft) front and 6.5 kg/mm (360 lb/ft) rear rates. Front is 27mm lower. Rear is 29mm lower. Handles like a f*cking dream around an autox course. I don't autox very often, so I'm not very good... but at the last autox, I was on street tires and didn't go to the practice, but was almost as fast as the S2000's that were on race tires, had done the practice day, AND had much more autox experience.

BTW, I should give some of the credit to my Kaaz LSD also - that helped a bunch also.
