When using the car on the track the cornering forces are bending the rubber in the wishbones (control arms). Thus changing the desired geometry of the car. This can lead to slower track times and ineffective tire usage.

For that reason we have come up with uniball control arms. Our race wishbones use metal to metal uniball just like used in Porsche RS line (GT2RS, GT3RS). Tested intensively on our Track Audi TTRS.

We are using same T45 tubing as in WRC cars, our wishbones provide increased stiffness and extra adjustment. All factory parts bolt up to this unit, no other modifications are necessary.

Product functionalities:
– Adjustment both caster and camber (up to -4.5 degrees)
– no rubber to bend, you will not loose the geometry set when doing aliment
– works with OEM subframe and our tubular subframe
– enables removal of the wishbones with our the need for removal of the subframe

– CNC machined 7075 aluminium insert and anodized in silver
– T45 (BS4T45 to BS4T100) tubing imported from UK and S355 metal sheets
– proven motorsport M18 uniballs (the same type we use in our Lancer EVO X kits)
– plug and play to use with the car inc xenon sensors

What is included:
– two (pair) front wishbones (control arms) with all hardware for install
– two CNC billet 7075 aluminium wishbone arm mounts
– four rubber caps for uniball protection
– printed install instructions

T45 is a very unique seamless carbon based steel tube that has been used in many applications in different industries. It is stronger than Co-Mo 4130 tubing that also used in motorsport. It is widely used in the aerospace sector in equipment such as pilot’s seats and crew’s seats due to the materials ability to withstand high G forces without snapping or splitting. This material is a Carbon Manganese based and conforms to the full Aerospace Specification laid down by British Standards.

Tensile: 700 – 900MPa,
0.2% Yield 620MPa minimum
Hardness Test: 201min – 262 max HB or 210min – 275max HV.

Note: It is possible to obtain TUV certificate for this product. Please contact us for more details.

Note 2: Sold for off road, track and racing applications only. Installation of this rear arm kit might introduce some additional some NVH (noise, vibration, and harshness) transfer into the cabin.

Note 3: Brake disc clearance is reduced by about 2[mm] in relation to OEM wishbones – keep this in mind, if You’re going to use aftermarket brakes with reduced clearance.
