Techie tidbit: VW now using titanium rear suspension springs!
but only on the Lupo FSI sold in Austria, Germany and Switzerland.
Other than a weight reduction, titanium's low shear modulus results in a shorter spring with fewer coils than a steel spring. How about that for lowering/adjustable springs for TT rear?
Bad news is the chance of aftermarket versions is probably nil. FWIW, Muhr and Bender in Germany are the producers.<ul><li><a href="http://aftermarket.theautochannel.com/articles/2001/01/11/012676.html">http://aftermarket.theautochannel.com/articles/2001/01/11/012676.html</a</li></ul>

Re: Techie tidbit: VW now using titanium rear suspension springs!
Doesn't Titanium suffer from a lack of a fatigue loading endurance limit? It would be interesting to see how many cycles such springs would take before they would just fail (snap).
Metals get weaker and weaker the more load cycles that they endure. Steels are special in that there is a magnitude of loading (the endurance limit) that is so low, that they will never fail. Keep the loading below this limit and avoid fatigue failures. Aluminum, for one, does not have this limit and will fail eventually, no matter how low the loads are.
Maybe I just paid too much attention in Engineering school...
