S2000 STR prep resource

I just reused my stock upper hats. I removed the metal sleeve from the assembly and then drilled out the two bushings. Then I put the moton upper perch on the shaft to assure a good axial spring relationship and then I slid the stock top hat and bushing down over the shaft. I did the same thing with my CRX. Shoot, I think the top hats for the CRX and the S2000 are the same.
If you're worried about the weight of the stock top hats, swiss cheese them. (yikes)

I was also thinking of swiss cheesing the top hats, well not exactly putting holes in them but cutting off the spring sleeves.

Shim? I don't understand why I'd need a shim. The bottom drilled out bushing sits on top of the Moton spring perch which sits on the shaft.
Ahhh, the spacer that goes between the OE bushings that keeps a set preload on the bushings once the assembly is torqued.
Nope, I threw that out. I just torque the nuts on top the shock shaft until the bushings look compressed enough but not too much.

When I installed my Club Sports, I modified the stockers and they work perfect! The stock bushings are almost all metal and very sturdy... Not like a set of bushings in the top hat of a civic for instance...

The GC tops contain a 2-piece urethane bushing. There is a horizontal 'shelf' that forms a cup inside the hat for the bushing halves to sit against. In my case, I'm using revalved koni yellows, so they are designed to accept the metal bushing that comes with the koni's. If memory serves, they weight around a half pound each.

What is an appropriate free length for springs based on travel? Shock body/threads may dictate otherwise. Are helper springs required? How much is practical to lower the car from stock?
I am planning to start at 600 lb all the way around and initially lower about 0.5 to 0.75 front and 0.75 to 1 rear. I daily drive my car, so it will be a tough balance. I don't know what free length to get and if helper springs are needed. I have a set of Penkse 8100s that are in the process of being rebuilt/valved with 600 lb springs in mind.
Life in stock class was so simple!

Sure! My front spring rate is about 1050lbs and rear is 700... Stock front sway bar. That's what is on the car at the moment.
However back when I had these shocks and was running street tires before I went all "BSP" on it, I was running 750 lb springs in the rear and 600lb springs in the front with a smidge of toeout in the rear, with a gendron solid front sway bar, with great success.... Smaller courses here though, and had to make the car want to turn
on a nationals course I think I'd try to tone it down some for the higher speeds.
