A Full Rear Suspension Cleanup for IRS Mustangs - Stage-3 Trac Bite System

The S550 and S650 chassis are great platforms,but the rear cradle can move around more than most owners realize. That shows up as wheel hop, vague rear-end feel, inconsistent launches, and excessive parts wear every time the tire unloads and grabs again. TheSPE Motorsport Stage-3 GT Trac Bite Systems are built to fix those issues with cradle lockouts, vertical links, and billet differential support, whether you are working with a GT, GT350, GT500, or Dark Horse.
