034 Motorsport Adjustable MQB Solid Rear Sway Bar Audi RS3 8V / TTRS 8S
 
034Motorsport's Adjustable MQB Solid Rear Sway Bar Upgrade for the 8V Audi RS3 & 8S Audi TTRS is engineered to improve the handling dynamics and balance of the ultimate iterations of these MQB-platform vehicles. Designed to be a bolt-in replacement for the hollow factory rear sway bar, this upgrade will drastically reduce body roll and understeer without sacrificing ride quality. Manufactured from a single piece of solid spring steel, this bar is over 50% stiffer than the factory unit, resulting in a much more balanced and agile car, which corners flatter and can be coaxed into oversteer as desired when driving through curves on the street or track. 
 
Please Note: For maximum effectiveness, we recommend upgrading to our MQB Audi/Volkswagen Spherical Rear Sway Bar End Links when installing this rear sway bar. 
 
Please Note: For lowered vehicles, always check all clearances over the full articulation of the suspension in order to identify possible interference. We recommend running 034Motorsport suspension components, as they have been designed and tested to work together, without interference.
 
034Motorsport is proud to offer the ultimate rear sway bar upgrade for the Audi 8V RS3 and Audi 8P TTRS! The 034Motorsport Adjustable Solid Rear Sway Bar is made from a single piece of high-quality, 0.938 inch thick spring steel for maximum rigidity, and is designed to combat understeer while reducing body roll under hard cornering.
 
This product was tested thoroughly on the street and track on 034Motorsport's 2018 Audi RS3 and 2018 Audi TTRS Development Vehicles, and multiple enthusiast-owned Audi MQB vehicles before release. The 034Motorsport Adjustable Solid Rear Sway Bar substantially reduces understeer and body roll on 8V Audi RS3 and 8S Audi TTRS vehicles without compromising comfort on the street.
 
In addition, the 034Motorsport MQB Rear Sway Bar is engineered to be used effectively with the stock front sway bar. No upgrade in the front is required. The addition of a stiffer front bar can positively affect turn-in feel, but ultimately worsens the platform's tendency to understeer. With the stock front sway bar and upgraded 034Motorsport Solid Rear Sway Bar, body roll is virtually eliminated while turn in and off throttle oversteer are greatly improved.

Sway Bar Rate Data:
034Motorsport (Soft) - 81% Rate increase vs. factory Audi RS3/TTRS (21.7mm x 3.0mm) hollow rear sway bar
034Motorsport (Stiff) - 102% Rate increase vs. factory Audi RS3/TTRS (21.7mm x 3.0mm) hollow rear sway bar
 
Recommended Alignment:
034Motorsport RS3 track use alignment specs; these specifications are optimal for a track driven car with a very "loose" handling attitude and lively rear end that drives towards oversteer. Caution should be used with these alignment specs as they can cause the car to over-rotate and spin, especially during throttle-lift conditions while turning:
Front: (Tires: 265/35-18 Michelin Sport Cup 2)
Camber: -3.0 degrees each side (034-601-1013 camber mounts)
Caster: 7.1 degrees (not adjustable)
Toe: 0.6mm (toe-in) each side
Rear: (Tires: 245/40-18 Michelin Sport Cup 2)
Camber: -1.5 degrees each side
Toe: 0.8mm (toe-in) each side
