The N-Tune rear bumper (Fiber Infused Technology) and rear under spoiler (Carbon Fiber) provides strength and durability during any type of motorsport environment.


  • Improves underbody airflow.
  • Pre-peg carbon fiber 2×2 weave materials to be strong and light weight.
  • Hardware kit (zinc plated screws, nylon-insert locknuts, etc.) & help guide.


  • Professional body shop experience in “custom” aftermarket aero in fiberglass/carbon fiber highly recommended. 

NOTE: CBA (08-11) GT-R applications will need to purchase DBA (2012+) OEM rear carbon fiber diffuser.  For DBA (2012+) GT-R applications, no additional hardware needed.

All N-Tune products are made to order. Please allow 3-4 weeks for production.
