PRL Subframe SRS Collar Kit for 2025 Honda Civic

Please note that increased overall rigidity of the chassis may cause additional vibrations and noise in the cabin when not cornering or braking.

In order to make sure a car is comfortable, quiet, and easy to use, the factory subframe has small gaps that allow the frame to move slightly during driving. For those looking to have go-kart like precision and overall chassis rigidity, PRL created the SRS (Subframe Reinforcement System) Collar Kit. These collars fill the small (usually 2mm) gap between the subframe bolts and mounting holes, which reduces slack and unwanted movement (chassis slop). Each collar is made of durable 6061 aluminum and anodized black for protection against road debris and the elements. The collars are precision machine, ensuring quality of the product and fitment assurance.

Key Features:

• Precision built to fill the small (usually 2mm) gap between the subframe bolts and mounting holes.
• Reduces slack and unwanted movement (chassis slop) in the subframe.
• Increases overall handling and rigidity, including steering sharpness and responsiveness
• Made from durable 6061 aluminum and anodized black.
