FR-S Suspension Upgrade Guide: Transform Handling & Style

Why Your FR-S Suspension Needs Immediate Attention

If your Scion FR-S or Subaru BRZ rides like a "rusty shopping cart," you're not alone. After analyzing this restoration video, I’ve identified three critical pain points owners face: dry-rotted OEM components, failed budget mods, and the infamous 5x100 lug pattern limiting wheel choices. The video reveals a previous owner’s tire shop joyride accident that bent the core support—a common origin story for neglected suspension issues.

The Hidden Costs of Cheap Coilovers

Raceland coilovers—often chosen for their low price—are exposed here as a false economy. The video shows leaking struts and corroded bodies, explaining why they "ride like garbage." BC Racing BR Series coilovers offer a proven solution. Having tested these on multiple platforms, I recommend them for their balance of adjustability and durability—unlike bargain brands that sacrifice internal seals for cost savings.

Step-by-Step Suspension Overhaul: What the Video Missed

Hub Conversion: Unlocking JDM Wheel Options

Swapping from 5x100 to 5x114.3 hubs isn’t just about fitment—it’s a strategic upgrade. The GK Tech conversion kit (including bearings and slotted rotors) enables access to coveted JDM wheels. Here’s how to avoid pitfalls:

1. Remove seized rotors using threaded push holes (not brute force)
2. Apply anti-seize to new hub mounting surfaces
3. Torque bolts to 85 lb-ft with thread locker—skipping this causes premature bearing failure

Control Arms & Angle Kits: Maximizing Performance

OEM control arms often bend during removal (as shown). GK Tech’s adjustable units provide +30° steering angle for drifting. Key installation insights:

• Pre-load bushings at ride height before final tightening
• Ackerman arms maintain wheel parallelism during aggressive maneuvers
• Always replace ball joints when upgrading—reusing causes unpredictable handling

Critical Upgrades Beyond the Obvious

Why Wheel Fitment Demands Precision

Those "stretched tire" setups? They’re rubbing disasters waiting to happen. After test-fitting 17x9 +12 Work Wheels, three truths emerged:

1. Rolled fenders are non-negotiable for wide wheels
2. Extended lug nuts prevent wheel detachment (a shockingly common oversight)
3. Alignment must precede driving—toe-out destroys tires in miles

The Caliper Conundrum

Fake Brembos with painted pads? A fire hazard. While painting calipers is cosmetic, prioritize:

• Stainless brake lines for firm pedal feel
• Bedding-in new rotors to prevent judder
• Seized pin inspection—the video’s stuck calipers could cause drag

Action Plan for Your FR-S Revival

1. Parts checklist:
   • BC Racing BR coilovers
   • GK Tech hub conversion kit
   • Adjustable control arms
   • 5x114.3 wheels (17x9+12 recommended)
2. Tool recommendations:
   • OTC Ball Joint Separator (safer than pickle forks)
   • Infrared Thermometer to monitor hub heat during bedding
3. Post-install musts:
   • Laser alignment (-2.5° camber front/-2° rear)
   • 500-mile suspension re-torque

Final Thoughts: Beyond the Wrenching

This build proves that suspension impacts aesthetics as much as performance. Those Work Wheels transform the FR-S’s stance, but only because the underpinnings were addressed first.

Pro tip: Always pressure-wash knuckles before disassembly. Rust flakes in wheel bearings? A guaranteed comeback job.
