H&R Sway Bars

H&R sells its anti-roll bars as Anti-Roll-Kits, uprated bars supplied with the hardware needed to fit them. The titles show which axles a kit covers. Most are listed simply as kits (“Stabi.kit”), those marked VA are for the front axle only, and those marked V+A include both front and rear bars.

Most kits come with a TÜV certificate, a good number with a part type approval, and some are listed without one. Choose a kit with the paperwork if your car is inspected after modification.

BMW, Volkswagen and Audi have the most kits, followed by Mercedes-Benz, Porsche and Skoda, with Mazda, Ford and Tesla among the others. The Audi A3 (8V), the Volkswagen Golf VII and Polo (9N) are among the models listed. The range also reaches the BMW 3 Series (G20), 4 Series (G22) and the 5 Series of the E28 era, as well as the Porsche 911.

Stiffening only the front bar usually pushes the car towards understeer, and only the rear towards oversteer, so a front-and-rear kit is the simplest way to keep the balance.
