JDC Under-Body Replacement Hardware Kit

The factory under-body panel and rocker panel molding fasteners are very susceptible to rust and oxidation, despite not driving on salted roads. With this kit, you can set your mind at ease that when your GT-R needs service, you won't have to worry about damaging these expensive panels due to "frozen" fasteners.

This Kit reduces time and effort spent on trying to remove oxidized fasteners while doing many under-body repairs, including but not limited to:
  • Alignments
  • Oil Changes
  • Exhaust system Repairs
  • And Many More...

Select from a full replacement kit including 124 Stainless Steel Pieces or 94 Titanium Pieces (and a packet of anti-seize), meant to replace all the main factory under-body fasteners, or you can select the rear section only, which replaces hardware in the carbon fiber rear diffuser only (52/36 Pieces). 

This kit also eliminates the possibility of future rust stains on these expensive carbon fiber or carbon-composite under-body panels!
