Our wheel base is extended by 4 inches.

More torsion strength than a round tube chassis. Increased headroom by lowering seats 4 inches.

The GT-427 Roadster chassis employs fully adjustable, custom-engineered, tubular-steel A-arms with coil-over shocks for the front suspension and a 4-Link rear suspension with coil-over shocks.

The GT-427 Roadster's suspension package was specifically engineered with an ideally responsive shock system to provide the smoothest ride possible!

Most replica bodies are made of polyester fiberglass, a very dated fiberglass material used in the early Corvettes®.

Ultimate Classic Cars use Vinyl Ester resins in a hand-laid tri-axial pattern. Vinyl Ester resin is stronger yet lighter, more flexible, less likely to delaminate and resists blistering that polyester resins are prone to experience.

Vinyl Ester has nearly double the heat tolerance which means your paint job will never ripple, develop spider cracks or unexpected air bubbles.

In addition to the extra 4" length, we have narrowed the transmission tunnel, giving us more length and width in the footbox. We have also made the doors wider.

This improves pedal placement, eliminates seat skew, and gives the GT-427 Roadster a roomy and more comfortable cockpit.

Seat tracks can be added in order to offer adjustable seats for a variety of drivers.

The interior features a custom dashboard with full VDO instrumentation, cut pile carpeting, steel-reinforced door panels and hand-stitched seats that provide excellent lumbar and lateral support.
