The features and benefits of our Mustang S550 IRS system are numerous!
- Equal-length double A-arm design with adjustable Toe and Camber. Geometry designed specifically for drag racing means launching HARD and STRAIGHT.
- 100-percent Tubular Chromoly construction is strong and saves weight. 110 pounds weight savings over stock!
- Subframe bolts in using all factory mounting points, with very little modification required for installation.
- Features Wilwood in-board disk brakes, reducing unsprung weight while allowing clearance to run an off-the-shelf 15-inch drag wheel(15x10 4.75 bolt circle).
- Fabricated 9-inch Ford differential housing offers endless gear ratio options and makes center section changes a breeze (9-inch gear set/differential not included).
- We proudly partnered with G-Force Engineering on the custom 35-spline axles, included with the Watson IRS kit.
- Billet aluminum spindles provide incredible strength and light weight.
- Highest quality components throughout: Aurora Bearing rod ends, HOWE precision ball joints (re-build-able), Wilwood brakes, and G-Force axles, combined with double-shear design and high-strength Chromoly mean this system was meant to last.
