Chevelle / GM A-Body

Designing a GT Sport chassis for the GM A-body had its own particular challenges; not the least of which was positioning the frame tightly under the body. The engineering team at Art Morrison Enterprises solved this problem with a unique angular frame rail that tucks right under the floor plan. This provides extra ground clearance and allows for a lower stance. Improving torsional rigidity was another consideration.

A stiff chassis enhances the ride, by putting the focus on the suspension. Up front the highly acclaimed AME Sport C6 IFS, with its specially designed tubular control arms and optimized geometry, Strange Engineering adjustable coilovers and adjustable anti-roll bar. Extensive development work on the suspension package has resulted in optimizing various parameters (camber angle, roll center, caster angle, COG, etc.) that delivers sports car-like handling with excellent ride qualities.

A superbly tuned rear suspension package includes triangulated 4-bars, 9” housing, adjustable coilovers and an adjustable anti-roll bar. For the ultimate in handling and comfort you can upgrade to AME’s Multilink IRS.
