Overview

The stock front rear lower control arm bushings on late-model Subarus are built for comfort first. They’re soft, they flex, and they wear out fast – especially if you actually drive the car the way Subaru intended.  

The Tomioka Racing Lower Control Arm Bushing (TR-CS2000) replaces those factory pieces with hardened rubber bushings that tighten up the front suspension, sharpen steering response, and stand up to aggressive street and occasional track use.   

This is a simple, high-value upgrade that takes slop out of the chassis without going to harsh solid or spherical joints.

Why upgrade your lower control arm bushings?

As the OEM bushings age and flex:

- The front wheels move around under load  
- Alignment changes more during braking and cornering  
- Steering feels vague on turn-in  
- You get more dive and instability over bumps  

By installing the TR hardened rubber bushings, you:

- Tighten up front-end geometry under braking and cornering  
- Improve steering precision and feedback  
- Increase chassis response without a big NVH penalty 
- Extend service life compared to the soft OEM rubber that often degrades in a few years 

Perfect if your car feels loose or “floaty” up front, or if you’re refreshing suspension on a higher-mileage Subaru.

Key features & benefits

- Front rear lower control arm bushing location  
  Designed specifically for the front rear position of the front control arms for a direct replacement. 

- Hardened rubber construction
  Uses a stiffer rubber compound than OEM to reduce unwanted movement while still being street-friendly. 

- Improved handling & stability 
  Reduces deflection under cornering and braking for a more planted front end and better confidence at speed.  

- Increased chassis response  
  Transfers steering and suspension inputs more directly, making the car feel sharper and more connected. 

- Durable, long-life upgrade  
  More resistant to tearing and premature wear than the soft factory bushings that often break down in 2–3 years on driven cars. 

- Sold as a pair  
  Includes both left and right bushings for the front lower control arm rear position.  

Vehicle fitment

Designed for late-model Subaru platforms that use this common front arm bushing:

- Subaru Impreza 2008+ (including WRX / STI models using the same arm style)   
- Subaru Legacy 2003–2009
- Subaru Outback 2003–2009 
- Subaru Forester 2008–2014 (model years using this arm/bushing design)   

> Always confirm bushing style and part number against your VIN or control arm P/N if you’re unsure about fitment.

Technical specs

- Part number: TR-CS2000 
- Location: Front control arm – rear bushing position
- Material: Hardened rubber
- Configuration: Replacement for factory rubber bushing  
- Quantity: Pair (left + right)  

What’s included

- 2 x Tomioka Racing hardened rubber lower control arm bushings (front rear position, left and right)  

Installation notes

- Press-in installation – we recommend having these installed by a professional shop with a press.  
- A four-wheel alignment is required after installation to reset camber and toe.  
- Ideal to install at the same time as front shocks/struts, coilovers, or additional suspension refresh (ball joints, tie rods, etc.).  

Recommended supporting upgrades

For a well-sorted Subaru chassis, pair these bushings with:

- Quality performance dampers or coilovers  
- Upgraded sway bar endlinks and sway bars  
- Stiffer engine and transmission mounts for a more connected feel  
- A performance-oriented alignment tailored to street, canyon, or track use  

Together, these upgrades transform your Impreza / WRX / STI, Legacy, or Forester from worn-out and vague to tight, responsive, and confidence-inspiring without making it unbearable to daily drive.
