Tomioka Racing Front Lower Control Arm Bushing - Subaru Impreza / WRX / STI / Legacy / Forester

Tomioka Racing Front Lower Control Arm Bushing - Subaru Impreza / WRX / STI / Legacy / Forester

The factory front lower control arm bushings on Subaru WRX, STI, Legacy, and Forester models prioritize compliance and comfort over precision.

Hardened Rubber Bushings That Actually Hold Geometry

The factory front lower control arm bushings on Subaru WRX, STI, Legacy, and Forester models prioritize compliance and comfort over precision. Under hard cornering and braking, that compliance translates to geometry movement -- the suspension does something different from what the alignment spec says it should. The Tomioka Racing Lower Control Arm Bushing replaces the factory pieces with hardened rubber bushings that tighten up the front end response without introducing the harshness of polyurethane.

Hardened Rubber vs Polyurethane

Polyurethane bushings deliver the tightest geometry retention but require regular greasing and introduce noise, vibration, and harshness that can become fatiguing on daily-driven cars. Tomioka Racing's hardened rubber design occupies the practical middle ground -- significantly stiffer than the factory soft rubber, direct bolt-in replacement with no greasing required, and quiet enough for daily use. For most street-plus-track builds, hardened rubber is the correct choice.

Straight From Subispeed

A worthwhile upgrade for any lowered or performance-oriented Subaru. The improvement in front end consistency is immediately noticeable -- corners feel more planted and the car responds more predictably to steering inputs. The hardened rubber formulation makes this a daily-driveable upgrade rather than a track-only compromise.
