What's expensive is not actually doing the threads, but adding the hex head. We had thought about making a slot for this reason, but this means that each kingpin has to go through an extra operation, vs just being made on a lathe.

Another thing is up-stoke can be limited with different height spring cups, where with a nut, you would have to use spacers on the king-pin to do so (or different size nuts, which also increases cost). I figure, this ends up being as much work as just adding shims to increase pre-load. :P

fair enough.... how about an adjustable clip position...jus like a jet needle on a motorcycle carb.....and using the same clips from the diff?

That's not a bad idea. But one thing I like about plastic clips is that they are SOOOOO easy to remove. The diff clips can be a pain in the butt. They would save space, but would make changes much harder. Isn't using shims easier?

Love the simple design.
I also like the plastic clips so much better than metal e-clips (like on the diff). Half the time I take off metal e-clips I end up bending them, losing them (as they shoot across the room), or drawing blood on my finger .
I agree plastic clips are the way to go as long as they are secure and have no chance of coming off in a race or high speed crash.

Wow! That was a smart invention.
Cant wait to try it out.
No more flexing arms, springs that can pop out in a crash, and so easy to change setup.
What about a WTF3?

Now cut the extra spring arm off the upper a arm and get even better bump performance by reducing the unsprung weight.
Great idea CT
Cannot wait to try in on the my 03 under the christmas tree

Very nice!. Simple, economical, and not much added weight and it looks like it will be effective. Great work!!!

Good work CT and Marcus -- I'd been trying to get a hold of some spare 03 pivot balls so I could stick 02 kingpins through them (essentially the same mod as you've done there), but now you've gone ahead and made the necessary bespoke part itself. Very nice. I just hope they are not gold-plated, but titanium-nitride coated. Gold plating isn't the right thing to do here for several reasons.

That is brilliantly simple! Or simply brilliant! I love it when engineering and efficiency match themselves up.
I'm a fan and will be putting it on my MR-03.

Amazing! I'm glad this is not a Front suspension kit with a $80 price tag and eight moving parts. I can afford five sets. One for myself; three for my enemies; the last one can be used for raffle.
