Adjustable tubular front race wishbones MQB Audi RS3 S3 A3 8V Golf Mk7 Seat Leon 5F

When driving a car on a track, the forces experienced in corners cause the rubber in the wishbones (control arms) to flex. This changes the desired geometry of the car, which was set on the toe-in stand. This can lead to slower track times and poor tire wear.

For this reason, we developed our control arms. Our racing control arms use a metal-on-metal uniball, similar to the one used in the Porsche RS line (GT2RS, GT3RS). Extensively tested on our Audi TTRS track car .

We use the same T45 tubes used in WRC cars, and our control arms provide increased stiffness and additional adjustability. All factory parts are bolted to this unit, so no other modifications are necessary.

Product functionalities:
- Both wheel and tilt adjustment (up to -4.5 degrees in tilt)
- no rubber that bends, you won't lose the set geometry while feeding
- works with OEM subframes and our tube frames
- enables disassembly of the wishbones when it is necessary to disassemble the subframe

Characteristics:
- T45 tube (BS4T45 to BS4T100)
- proven M18 motorsport uniballs (the Motorsport HEAVY DUTY series from RODOBAL [Italy] with a reinforced PTFE anti-friction insert, pre-tensioned for a tight fit, have a forged body made of heat-treated 42CrMo4 steel for maximum load capacity. The inner ring is made of 100Cr6 carbon steel, hardened, ground and chrome-plated.)
- Plug and Play for use with automotive xenon sensors
- possibility of adding air ducts to the Audi 8V wishbones (air ducts not included in the kit)

What's included:
- two (a pair for one car) front wishbones with all mounting hardware
- four rubber dust caps to protect the uniball
- printed installation instructions

T45 is a unique seamless carbon-based steel tube used in a variety of applications across industries. It is stronger than the Co-Mo 4130 inner tube also used in motorsports. It is widely used in the aerospace sector in equipment such as pilot and crew seats due to the materials' ability to withstand high G-forces without cracking or fracturing. This material is carbon-manganese-based and complies with full British Standards aerospace specifications.

Properties
Tensile strength: 700 – 900 MPa,
Efficiency 0.2% Minimum 620 MPa
Hardness test: 201 min – 262 max HB or 210 min – 275 max HV.

Note: Sold for off-road, track, and racing applications only. Installing this rear control arm kit may result in additional NVH (noise, vibration, and harshness) being transmitted into the cabin.

Note 2: Brake disc clearance is reduced by approximately 2 [mm] compared to the OEM control arms - keep this in mind if you intend to use aftermarket brakes with reduced clearance.
