Nissan Skyline R34 GTR Rear Lower Carbon Fiber Diffuser V-Spec/N1 Finisher Fin Mount Bolt Collar (Center)

Accurate restoration of the iconic carbon fiber rear diffuser on an R34 Skyline GT-R V-Spec or N1 demands every original component to achieve factory-correct fitment and structural integrity. The Genuine Nissan Rear Lower Carbon Fiber Diffuser Finisher Fin Mount Bolt Collar is the authentic OEM steel spacer used exclusively on the middle left and right vertical fins. This precision-machined collar features the correct outer diameter, inner diameter, thickness, and height to properly interface with the finisher fin mount bolt, ensuring a secure, vibration-resistant installation that matches the original assembly.

These collars are frequently lost, damaged, or discarded during diffuser service or fin replacement after racing or aggressive street use. Installing the correct OEM collar restores precise alignment of the plastic vertical fins through the diffuser, preventing misalignment, rattling, or premature failure. Six collars are required for the left and right center fins combined (three per individual fin), making this a critical hardware item for complete and authentic diffuser repairs.

At Terra Firma Automotive, we supply this genuine Nissan Finisher Fin Mount Bolt Collar as the trusted solution for R34 GT-R V-Spec and N1 owners. As a brand-new original Nissan unit made from steel, it delivers exact dimensional accuracy and factory-level durability that aftermarket substitutes cannot replicate. Whether replacing broken fins after track use or completing a detailed rear-end restoration, this OEM collar ensures your carbon fiber diffuser looks and functions precisely as Nissan engineered it.
