Since 1999, APR has been developing and producing software and electronic modules for VAG Group vehicles. On top of this come turbo kits, superchargers and many performance parts. Today APR, based in Opelika in the USA, has become the world’s largest supplier of tuning and performance parts for the VAG Group.

Since 2009, APR has been available in Switzerland with DTC homologation for most vehicles, so that you can drive completely legally. Rupteur chose to work with APR for the quality of its products and its remaps, which we consider the most aggressive on the market while offering flawless reliability. We offer a tailor-made service for these cutting-edge products, in line with APR’s motto "Tuning without Compromise"
