SPC Performance 81368 B8 Audi Racing Arm Set

The SPC Performance 81368 is a four-arm adjustable upper link set engineered for B8-platform Audi models seeking serious performance gains on the track. This complete kit allows independent adjustment of both camber and caster up to ±1.5° on each side of the vehicle, giving drivers precise alignment tuning capability beyond what the factory suspension allows.

Key Features:

• Four-arm kit — complete set for full front upper link replacement on both sides
• ±1.5° camber and caster adjustability per side for dialed-in alignment settings
• xAxis sealed flex joints replace factory inner bushings with a free-pivoting, minimum-compliance joint for superior steering response and feedback
• Dramatically reduced compliance compared to OEM rubber bushings for sharper, more predictable handling
• Sealed joint design for durability in demanding track and performance street environments

Important NVH Notice: The factory OEM bushings are specifically designed to absorb and isolate noise, vibration, and harshness (NVH) from the cabin. By replacing them with SPC's rigid xAxis flex joints, increased road and mechanical noise transmission into the cabin should be expected. This trade-off is intentional and typical of performance-oriented suspension components — the gain in handling precision comes at the cost of NVH isolation.

The SPC Performance 81368 is the ideal solution for track-day enthusiasts, autocross competitors, and performance drivers looking to maximize the suspension geometry of their B8 Audi platform.
