About
What Achtuning means
Our name is derived from the German word “ACHTUNG”, which translates to attention or respect in English. Combine “Achtung” with the word “Tuning” and you have Achtuning … pronounced ‘Ock-tuning’. If you own a German car, take a look inside your engine compartment sometime; you’ll find “Achtung!” all over the engine bay!
Origins
Achtuning was founded in 2001 by Joshua Decker. It all started with a shift knob that Joshua began to import from Germany and sell online. Soon after, Josh had sold over 600 of these and found himself importing everything from turbos to full RS4 body kits. This hobby turned into a full time passion and Achtuning was born. Josh’s background in German cars goes all the way back to driving his first VW, a 1986 VW Jetta GLI. Since then he has owned 10 Audi’s and VW’s and now drives a 2000 Audi S4. Josh decided to sell the Achtuning name to Bill Spencer, owner of Hartmann Wheels, in 2006. Regarding this transition, Decker says “This is a great opportunity for everyone involved. Bill has the resources and solid customer service reputation needed to see the Achtuning brand achieve it’s potential. I’m sad to leave but I’m excited to know that the name I created will live on and become the success I always imaged it could be.” Josh has since focused his efforts on his successful aftermarket racing seat company, Status Racing Inc. (www.statusracing.com). In 2009 Josh founded a new internet forum for Audi enthusiasts, QuattroWorld (www.quattroworld.com) which is already one of the top Audi forums on the internet.
