I designed SmartStrings about 21 years ago, to perform precise alignments in my garage at home.

Roland Kussmaul has been involved with developing every racing car Porsche has built since 1975, from Le Mans-winning sports cars, to Paris-Dakar Rally-winning cars, to winning Indy cars, to the complete decade-long dominance of Group C prototypes, to the GT3 Cup and GT3 RSRs, as well as the famous RS Spyder. If you're interested in hearing the inside story of how these successes came to be, told as a narrative, the truths are in this book.
