I like the vents, maybe some pictures from the inside on how it's duct through. Good look.

Forgive my ignorance in my questions. It's been a while since I messed with suspensions. My limited experiences was open wheel cars and that was torsion bar technology. Coilovers were just begging to be seen at the local track. In fact my friend was an engineer and he was experimenting with them. Most of what I learn he taught me, that and Physics in college.
My question is how do you adjust the "rate" of a spring without having to change the spring?
When you talk about "preloaded", are you actually compressing the spring? If so how does it change the "rate"?

Hooke's law is a principle of physics that states that the force needed to extend or compress a spring by some distance is proportional to that distance. That is F=kX where is k a constant factor characteristic of the spring, its stiffness.
BTW, it's been so long I had to google Hooke's law, did not pull it off the top of my head. :-)

So what all can effect the 'k'. Size of wire, material, diameter of the coil, and etc... What little googling I did, there was a technology where the spring attached to a lever and by changing the connecting point, there by the length of the lever, you could adjust the "rate".
So how is the rate changed? This whole discussion if fascinating. Have not been to a track in years, but back in those days your competitor did not share much. I mean they did help you with enough setup to keep you safe, but not much to make you fast. :-)
