Engineered for maximum grip, tyre longevity, geometry control, and steering precision, Eastwood Engineering’s extended inner lower control arms are designed for high-performance Porsche chassis where alignment accuracy, strength, and repeatability are critical.
Fitment:
- Porsche 991 GT3/RS / GT2 RS – front axle only
- Porsche 981 Cayman GT4 – front & rear axles
- Porsche 718 Cayman GT4 / GT4 RS – front & rear axles
The revised geometry increases track width by +10 mm per side, while enabling substantially higher negative camber settings—essential for maximising tyre contact patch and maintaining consistency under heavy braking and high lateral load. Extended high-strength studs allow increased shim capacity, making precise, repeatable camber adjustment possible during alignment and trackside setup changes.
Factory rubber compliance is fully eliminated and replaced with motorsport-grade, Teflon-lined FK spherical bearings, significantly reducing deflection. This delivers sharper steering response, improved feedback, and more stable behaviour at both ends of the car under load.
These control arms inners are designed as a true bolt-on upgrade, requiring no modification or manipulation of factory suspension components. OEM rubber part remain unaltered, allowing the vehicle to be returned to standard specification if required or can be transferred to another vehicle
Motorsport Features:
- CNC-machined from 2618-grade billet aluminium for maximum strength and fatigue resistance
- Motorsport-grade, Teflon-coated FK spherical bearings
- Extended-length Grade 10.9 high-strength studs for increased shim capacity
- +10 mm track increase per side (per axle where fitted)
- Increased negative camber adjustment range
- Zero rubber compliance for maximum geometry control

Sold as a pair
Fitment Note:
Track increase and camber gains apply per axle where fitted. Front-axle-only fitment for 991 GT3/ RS / GT2 RS.
Track Use Disclaimer:
These control arms are designed for track and competition use only. Removal of factory rubber bushings will increase noise, vibration, and harshness (NVH) and may accelerate wear of related components. Not recommended for daily road use. Professional installation and alignment are strongly advised.
