Powerflex Black Series Front Suspension Tension Strut/Thrust Arm Bushes/Bushings (Polyurethane) for BMW 3 Series G20 G21 2018-on – Lower Control/Radius/Caster Arm – PFF5-2501

Unlock sharper steering, rock-solid braking stability and long-term reliability on your BMW 3 Series G20 and G21 with this uprated front tension strut bushing kit from Powerflex. Built for drivers who want precise front-end control without the short service life of rubber, this is the go-to polyurethane upgrade for fast road and track day use.

Part number: PFF5-2501

What it does

• Replaces the factory rubber thrust arm mounts with motorsport-grade polyurethane for far less deflection
• Up to three times the rigidity of the OE item for confident braking and consistent geometry under load
• Holds alignment steady through cornering - improves turn-in, feedback and tyre contact
• Supplied with precision steel outer sleeves for accurate location and durability

Why enthusiasts choose this upgrade

• Black Series 95A compound for maximum control on performance builds
• Polyurethane resists oil, road salt and heat - vastly longer life than rubber
• Crisper steering feel and reduced fore-aft hub movement under hard braking
• Excellent for spirited road driving, track days and tuned G20 and G21 platforms
