Thanks for chiming in with more excellent pro input! It would be great if more of this kind of specialized bespoke diff service was available stateside. For the price of a shiny set of wheels one could contemplate a potentially significant and customizable high-tech performance upgrade...

Maybe you could sell through Turnermotorsport or a similar high reputation race-oriented US vendor?

Anyhow, fun times in the old country (I am from Germany originally, but that's a long time ago).
