HPerformance has been working intensively on the Audi TTRS 8J since 2009, continuously developing powerful, TÜV-certified performance levels. With the release of the TTRS 8J in March 2021, we were able to transfer our experience directly to the current model and now offer road-legal upgrades with up to 707 hp. For customers looking for even more power, we also manufacture export stages with over 900 hp. All components - from software and mechanical parts to our own turbochargers - are manufactured in-house. This complete control over development and production ensures the highest quality, maximum stability and perfect tuning. HPerformance supplies everything for the TTRS 8J from a single source - made in Germany, with motorsport expertise and passion.
