Differential Integration and Reinforcement System - reinforce your differential case and improve your car's IRS operation and traction with the DIRS! 100% satisfaction guaranteed.

New transformative product from Per4Mance Development: Starting in January 2019, P4D decided to take a fresh look at the differential brace taking into consideration what has worked and what could be improved. Working with a new mechanical engineer, they started with a blank sheet of paper.

P4D's goal was two-fold:
  1. Could they develop a better solution?
  2. Could a new solution be more harmonious with the OEM IRS
This led them to develop a two-piece differential integration and reinforcement system.
  • Part one attaches the differential using the lower two main case bolts and the three lower case bolts to reinforce the differential.
  • Part two attaches to the rear cross-member and carries an OEM differential bushing (just like the two in the rear cross-member) to add a third, triangulated integration point to "attach" to the reinforced differential.
Features:
  • American made and CNC machined T-6061 billet aluminum
  • OEM differential bushing
  • ARP fasteners/US made galvanized bushing bolt
  • P4D tool-less PEM inserts for cross-member attachment
  • Hard anodized coating in black (images are of preproduction units)
  • Access to fill and drain plugs
  • Typically ships in 24-48 hours
User reported observations and benefits:
  • Product Quality and Packaging
  • Strength and Robustness
  • Improved rear-end dynamics including increased traction/less wheel hop
  • No increase in NVH

IMPORTANT:
The DIRS is not compatible with BORLA aftermarket exhaust systems. Contact us if you’d like a DIRS and run Borla exhaust.
 
IMPORTANT:
Use of the DIRS may impact the manufacturer's warranty on the differential. Purchaser assumes all responsibility for installation and use.
