  • Density Line Control Arms for B8/B8.5 Audi A4/S4 & A5/S5/RS5

    If you've been waiting for an affordable, high-quality solution to replace your worn factory control arms, 034Motorsport has great news for you!

    Complete Density Line Performance Control Arm Kits are now available for the B8/B8.5 Audi A4/S4 & A5/S5/RS5! These are designed to be the most comprehensive and effective OEM+ control arm kits on the market, and include everything needed to replace the factory arms and ball joints, along with new hardware.

    The factory front control arms are an integral part of the B8/B8.5 Audi A4/S4 & A5/S5/RS5 suspension, but can start wearing out as early as 40,000 miles - especially on enthusiast-owned vehicles which are driven hard on the street or track. As the rubber bushings degrade and ball joints develop play, alignment is compromised and steering becomes less precise.

    034Motorsport's Density Line Control Arms are designed to be performance replacements for the factory front control arms on B8/B8.5 Audi models. Featuring high-durometer rubber bushings and high-quality ball joints, Density Line Control Arms are engineered to limit unwanted deflection in the suspension, resulting in tighter handing and more precise steering response than even brand new factory control arms can offer.

    • Offers Improved Handling Feel & Steering Precision
    • High-Durometer Rubber Bushings (65 Durometer)


  • Billet Aluminum Strut Brace for B9 Audi A4/Allroad

    034Motorsport is proud to offer our Billet Aluminum Front Strut Brace for the B9 Audi A4! The factory Audi strut brace is made of thin stamped aluminum, allowing for lateral deflection of the strut towers and chassis flex under hard cornering. This deflection can be observed as imprecise steering input and a vague, disconnected feeling from the front end.

    Chassis Reinforcement Strut Brace for Audi B9

    The 034Motorsport Strut Brace replaces the flimsy individual factory braces to improve the B9 A4's steering feel and handling performance. This robust chassis reinforcement is machined from T6-6061 billet aluminum, and engineered to be a comprehensive upgrade by limiting lateral strut tower deflection and maintaining proper suspension geometry under heavy cornering. The incorporated center brace ties together both left and right strut tower to provide precise, consistent feedback from the front end and ensures that you enjoy a more connected driving experience.

    This year marked the fourth annual WinterFest Meet & Greet/Open House/Dyno Day/Bonanza put on by NorCal Audi Club and hosted at the 034Motorsport headquarters in Fremont, CA. The forecast may have called for 5 inches of rain on the day of the event, but that didn't stop people from making this year's event the best WinterFest yet!

    Crowds look at modified Audi and Volkswagen Cars at 034Motorsport

    A variety of 034Motorsport-tuned cars were on display inside the service bay, including the shop's R460 8V Audi S3 that recently won European Car's 2.0T Tuner GP.

    Facility tours were given throughout the day, allowing customers a look behind the scenes of 034Motorsport's Machining, Manufacturing, and Shipping departments.

    Volkswagens and Audis flowed on and off the dyno like clockwork during the entire event, while spectators and owners alike wagered what power numbers would be put down by each car. A huge thank you goes out to the 034Motorsport employees who efficiently organized, staged, and secured every participating car on the dyno throughout the day.

    034Motorsport's President and Founder, Javad, cooked up a hearty 15 gallons of home-made chili with slow-braised pot roast to satisfy the crowd that had gathered by mid-day. Record amounts of onions, cheese, and Fritos were consumed as a result.

    Generations of Audis and Volkswagens showed up, filling the parking lot with what seemed like almost every hue from the VAG color palette over the past 17 years.

    Iconic cars from Audi's history took to the dyno, including examples of the early turbocharged 5-cylinder fury and the later naturally-aspirated 4.2L V8.

    We were ecstatic to have such a great turnout for the 4th annual WinterFest, and thrilled that so many people were willing to brave the weather for this event. With no actual rain falling, it proved to be well worth it! Thank you to everyone who attended, NorCal Audi Club for organizing the meet, and to all of the 034Motorsport Team who prepared the facility and helped run a seamless Open House. With the growing success of these events each year, SummerFest 2017 will surely be the best yet! We'll see you then!
