Koni Yellow / Autocross
 

I will be installing Koni Yellows this week on stock AP2 springs. I like to hear how you are setting the stiffness for some starting points.

lots of into here for street and ax settings. Where are you running out of?

Setting shocks is going to be variable dependent on a lot of things. Your driving technique, the surface, the rest of the car setup, etc. So there is no one size fits all here. I recommend starting dead middle of the range and tuning from there. When you start tuning, make big adjustments so you can see the effect. I started to add a chart I had for this but it keeps messing up on me. There are tables out there on the net for the effects of adjusting rebound/compression that are helpful

I'd start in the middle with the same settings front and back and feel it out. I believe most 1 way shocks are mainly rebound adjustment. Confirm for yourself what each turn of the knob does, IE which way opens and closes the valve. I referenced this link when setting up my car:

Understanding rebound adjustment was slightly counterintuitive for me until I understood what I was actually adjusting. Don't think about shock settings as making the shock stiffer or softer because the effective spring rate is still the same. Think about it more as controlling weight transfer and motion. It's easy to adjust yourself into a hole if you don't know what your doing and trying too many things at once.

Correct, shocks only have effect when the spring is compressing or rebounding and have the effect of affecting the speed that weight transfers. Yellows are "rebound only" but they have crosstralk and do affect compression as well. Not uncommon for many singe adjustable shocks. They also are not super linear near the extremes ends of the adjustment so play around and find what works for you. I ran yellows for a short while but they will not handle rates above about 500 lb/in or so. Above that they just do not do well. I was going to STR so I moved on to something else. Something to be aware of if you ever start increasing spring rates.

A friend who autocross his S2000 with Koni Yellows. A quarter from diff in the front and a quarter from full soft in the rear. He told me he tried so many different setting and found this to be the best in his driving style. The best is that you can experience and found out the best for you. Just remember to try them in small increments. With additional parts too. Best of luck.
