C4 SLA/IRS installed in a 3rd gen Camaro
This all began with a challenge from my brother that this could not be done. I took a rolling chassis of a 92 Corvette and installed it in my 84 Z28. It started with removing all of the brackets and sheet metal associated with the live axle rear suspension, K-member, and front strut suspension. The rear frame rails were reinforced with 3/16” plate formed to the C-notch where the original coil springs resided and new fabricated brackets for the C4 center section were installed. The rear wheel wells were widened 1 ½” and pockets formed for the upper and lower control arms in the forward section. The strut rods, control arms, and toe rods were fabricated with rod ends and CrMo tubing. A pinion support was added to the transmission tunnel and uses a poly body mount. The front frame rails were sectioned 18” and new 30” rails were installed at 13 degrees for improved anti-dive geometry. Brackets for the upper control arms and coil-overs were attached to the frame rails. A custom designed K-member was fabricated to accommodate the LS engine and rack and pinion steering and positioned 2 ½” back and 2” lower for better weight distribution. The transverse leaf springs were replaced with coil-overs with 400 lb. springs front and 300 lb. springs rear. Splined front and rear anti-sway bars round out the suspension. All of the design, engineering, and fabrication was accomplished in a 2 car garage with no lift or frame table.
