Spring Rate Conversion chart:

Cliffs: Easily Convert KG/mm to LBS/in

Roughly 1 KG/mm is equal to 55.997 LBS/in. Easy way to remember is 1 KG/mm = 56 LBS/in.

Nice catch, I saw ad well but I had yet to check the website. I’ll research now, thank you.

I appreciate the thought and testing in the anti-slip camber design. I also like the inclusion of adding caster for improving high speed stability.

I pause at the cost and I’ve already purchased PCI units. I value quality engineering and design, it’s just difficult given this new world of Honda parts costs impacting tracking.

I presume the Kingpin Machine upgraded sphericals from the PCI would still work. We shall see.

I think they would since the Honed kit doesn't include the bushings and I probably will have to swap mine over.

I did end up buying the honed kit. I am still using the skunk2 kit that came off Christian's old car, but with the kind of driving my car has seen on the track and autocross, it feels like preventative maintenance on changing it up again. I'll eventually install them after I get my car running again. Waiting sucks

I'm considering the kit. I could do a write up comparing three different setups with pics, weights, camber adjust & caster specs, etc.

I would be interested in learning your feedback because I saw the price and thought that seems like an awful lot, but perhaps it's well-engineered and high quality so does it fall into that category or "you get what you pay for?"

I’ll buy a Honed set if I can secure a buyer for my current BNIB UCA’s. I’ll do a full comparison, pictures, compare weights, and features.
