Ultra Racing rear anti-roll bar 19mm for Audi A4 B8 (Typ 8K)
Ultra Racing’s rear anti-roll bar 19mm is a vehicle-specific chassis upgrade for the Audi A4 B8 (Typ 8K). A stiffer anti-roll bar helps reduce body roll in corners and gives the chassis a tighter response.
Ultra Racing specialises in chassis and suspension bracing, with a range covering upper, lower and mid braces, fender braces and anti-roll bars. The idea is to reinforce strategic areas of the chassis without major structural modification. Ultra Racing states that its brace brackets use 4–5 mm steel plate, while its hollow steel tubes are typically 1.2–1.6 mm thick.
An anti-roll bar is a straightforward way to sharpen the Audi A4 B8 (Typ 8K) without replacing the entire suspension. It also works well alongside other handling upgrades.
