Performance Adjustable Front Tension Rods for BMW G8X M3/M4 Base/Competition & G87 M2

Upgrade your G8X M3/M4 or G87 M2’s front suspension with Our’s Performance Adjustable Front Tension Rods—engineered to eliminate the weak link in BMW’s factory upper control arms.

While the stock arms (P/N 31108095667 / 31108095668) handle daily driving and back-road blasts just fine, their soft rubber bushings betray you on track. Excessive deflection under load dulls steering response, introduces unwanted toe change, and robs you of consistency lap after lap.

Our solution replaces that compliant rubber with premium JMX hardened, PTFE‑lined FK spherical bearings. These low‑friction, high‑misalignment rod ends deliver silky‑smooth articulation with zero slop, giving you instantaneous steering feedback and a planted, predictable front end that inspires confidence through every corner. The chemically bonded Teflon liner ensures exceptional dynamic wear resistance and high load capacity—so it’s tough enough for competition, yet refined enough for street use.

More than just better bearings – these tension rods add caster adjustability to your alignment toolkit. Dial in precise caster for sharper turn‑in, fine‑tune left‑to‑right balance, and compensate for production variances to extract maximum grip from your tires.
