Had a long and very informative conversation with Todd at Vortrag (http://www.vortrag.com) about Coilover suspensions. For less then the price of the ABT Executive blah blah, Todd can create a yellow Koni based coilover suspension for an car. So any experience on this list with Coilovers on any Quattro's?
