I admit, a $750/each pricetag is high, and I did not state it to elevate myself to "ballah" status. I figued since people seem to be willing to pay $200 for a simple Ti key, they would be interested in knowing what these might cost them. Since I did all the labor, I only had to pay for the material and thus only paid a fraction of $750. IMO a true ballah buys something simply because it costs more than all the other options and this is their only way of achieving satisfaction. The problem with $750 each is the low build quantity and the high percentage of setup costs rolled into just two parts - custom steel springs would not be much cheaper at this quantity. The price would certainly go down as the build quantity was increased with it leveling off at around $350 each @ qty 20+. I don't want to be a salesman here, but besides simple pound for pound weight savings, Titanium as a spring material brings other performance benefits to the table such as higher natural frequency, tighter packaging than equivalently spec'd steel springs and being virtually impervious to corrosion. The natural frequency really comes into play when you consider the engine spinning at high RPM induces a harmonic into the rest of the chassis. We have video of a vehicle on a chassis dyno that shows their steel suspension spring vibrating uncontrolled to the point that they lose traction and had to abort the test. The rear of the vehicle actually dropped because the spring wasn't capable of controlling itself let alone holding up the weight of the vehicle. Replacement with a Ti equivalent moved the natural freqeuency to a much higher level than the vehicle was capable of generating and the problem was solved.
