Hardrace Honda Civic Type R (FL5/FK8) Rear Subframe Reinforcement Brace
This Hardrace rear subframe brace ties the rear mounting points together to cut flex in the chassis. It is made from high strength, light weight 6061-T6 aluminium. By reducing movement at the rear of the car, it keeps the suspension working as it should, especially when cornering hard.
The result is steadier handling, sharper steering feel, and more consistent grip. You will feel more confidence through quick direction changes and mid-corner bumps. It will not turn the car into a race car on its own, but it is a smart upgrade that works well with good tyres, alignment, and suspension.
Why fit this brace?
- Cuts rear subframe flex, so geometry stays stable under load.
- Improves handling response and mid-corner stability.
- Helps the tyres keep better contact with the road.
- Lightweight aluminium design adds minimal weight.
- Tough 6061-T6 material for strength and durability.
Installation
Designed to mount to the rear subframe. A competent home mechanic can fit it with normal hand tools, though many prefer professional fitting. No special setup is needed beyond correct torque settings.
Important: If any subframe or suspension bolts are loosened during installation, torque them to the manufacturer’s spec. After any suspension work, it is wise to have the wheel alignment checked.
