MQB Motorsport Roll Center and Camber Adjustable Ball Joint

Ball Joints are on backorder, ETA end of March, 2026

We are accepting a limited number of pre orders out of the next production run. Ball joints are sold in pairs with all necessary hardware.

Unlock the Front-End Grip Your MQB Chassis Deserves with the RCCA Ball Joint

The MQB platform has earned its reputation as a standout performer on both street and track, consistently punching above its weight and surprising countless people with it's abilities. However, when it comes to front-end grip, enthusiasts quickly encounter two key performance limiting factors: traditional camber plates typically max out between -2.8° and -3.2° of camber and lowered cars suffer from poor roll center geometry. Extensive chassis and tire testing has shown that many modern performance tires deliver their best track performance  with even more camber. Depending on the tire/chassis setup, optimal camber can be in the -3.6° to -3.8° range, with some setups benefiting from even more. In addition, many OEM style ball joints fail prematurely due to excessive heat generated by hard track use.

Precision Camber Gains Without Compromise for the ultimate in Adjustability, Durability and Serviceability

The all-new 529 Innovations RCCA (Roll Center and Camber Adjustable) Ball Joints unlock up to an additional 1.8° of negative camber in many cases allowing for up to -5.0° of usable camber AND, up to 20mm of roll-center correction. This allows drivers to achieve optimal alignment and improved suspension kinematics. For the “stance crowd” we have been able to get over -5° of camber when paired with proper camber plates and our upcomming max camber adapters!

Beyond alignment performance, the 529Innovations ball joint is engineered to solve three common issues found on MQB VW and Audi vehicles , durability, “big brake kit” issues and dangerous, on-track alignment changes, resulting from traditional slotted designs slipping under high load conditions.

• By replacing the plastic-lined socket with an oversized, commercially available, motorsport-grade spherical bearing, the 529Innovations ball joint significantly improves heat resistance, durability, and consistency in this critical suspension location.

• Additional clearance—up to 5mm of additional rotor clearance compared to OEM type designs—helps eliminate interference with many common big brake rotor sizes ranging from 340mm to 380mm.

• Large brake packages often create tight clearances at the factory ball joint, leading to excessive heat soak and premature wear. The OEM plastic-lined socket design is especially susceptible to damage under sustained high temperatures.

• A two piece design with a positive locking, serrated interface ensures that the camber plate cannot slide, even under the highest of cornering loads.

Features

• 7075 billet aluminum body that has been heat treated, stress relieved and hard coat anodized  

• Robust teflon lined spherical bearing with optional, low friction, all metal bearings.

• Heavy-duty chromoly billet steel ball joint pin with a proprietary heat treat and finishing process

• The spherical bearing and ball joint stud are user serviceable and available as a service item kit without the need to replace the entire ball joint assembly.

• Unique two-piece body design with a precision serrated adjustment interface provides a secure camber adjustment of the ball joint

• The bottom plate positively locates using the OEM control arm mounting holes , preventing the ball joint from slipping.

• Ability to percisely align the vehicle after the addition of of subframe locking collars .

• The slotted upper body design is compatible with all control arm designs that use the OEM ball joint mounting pattern, including the 8S (TT/TTS/TTRS) aluminum arms
