PRL Motorsports Subframe Reinforcement System Collar Kit – Civic Type R FL5 (2023+)

Improve steering precision and chassis rigidity in your 2023+ Honda Civic Type R FL5 with the PRL SRS Subframe Collar Kit.

From the factory, the 11th Gen Civic features oversized subframe mounting holes—2mm larger than the bolts—introducing slack that allows the subframe to shift under aggressive cornering or braking. This design compromises steering sharpness, handling response, and can lead to unwanted vibrations or rattles.

PRL Motorsport’s SRS (Subframe Rigid System) Collar Kit addresses this issue by precisely filling the 2mm gap around each subframe bolt. The result is a tighter subframe fitment, enhanced chassis stiffness, and more predictable handling dynamics—perfect for spirited street driving, autocross, or track use.

• Reduces subframe movement by eliminating OEM slack
• Enhances handling, steering response, and road feel
• Minimises vibrations and subframe shift under load
• Ideal for track, autocross, or improved daily driving
• CNC-machined from durable 6061 aluminium
• Black anodised finish for long-term corrosion resistance
