Many drivers may not be aware of the significant slack present in their vehicle's factory subframe, which arises because OEM engineers often need to balance performance with factors like comfort, cost, or ease of assembly. For instance, the subframe mounting holes in the 11th Gen Civic are 2mm larger than the bolts, allowing for shifts, vibrations, and rattles during intense cornering or braking. This can reduce steering sharpness and responsiveness. At PRL, WE PRIORITIZE PERFORMANCE, which is why we developed the SRS collar kit to eliminate this slack.
The PRL Motorsport SRS Collar Kit effectively counters these issues by precisely filling the 2mm gap around the subframe mounting bolts, ensuring a snug fit that prevents any extraneous movement. This adjustment significantly cuts down on vibrations, boosts handling, and increases chassis rigidity, making it ideal for track days, autocross, or simply enhancing everyday driving. Constructed from durable 6061 aluminum and anodized black, these collars ensure lasting performance and reliability.

This downpipe has been one of my favorite upgrades to the FL5. Installation went smoothly although I had one issue with the heatshield where the holes didn't fully line up with the DP. Otherwise, would've given 5 stars.
Feeling at ease knowing if something happens, they got you covered, is priceless. Worth the extra dollars.
Well designed, makes power and sounds awesome.
