For Ones That Favor the Open Air

Our existing Coupe restorations provide an exceptional analogue driving experience on any road or track, so to heighten the experience even further, Gunther Werks developed a new open-air model. Taking styling cues from the legendary Speedsters of the past, we developed our own Speedster. With its shortened windscreen and lack of side windows the open-air experience has been cranked up to maximum. With no roof, the soundtrack of the glorious 4.0L flat six can now be heard in full, this adds another dimension to the whole driving experience. Couple all of this to the rush of wind through your hair, and you feel even more connected to the road in a way no other car can. This is analogue in its purest form.

Engine

Our 4.0-liter has been meticulously developed by Rothsport from Oregon to our specifications, to create the ultimate naturally aspirated flat-six. The original crank case is starting point for all of our engines, from there the Mahle pistons to the twin map Motec Engine management, coil over plug ignition, individual throttle bodies, billet crankshaft, rods & barrels, no moving part of the engine is left untouched. The net result is: a 7800 rpm redline, 330lbs feet of torque, and 430+ horsepower.

Transmission

The original Getrag G50 is retained but rebuilt with completely bespoke custom ratios.

The shift linkage is upgraded, a single mass mid-weight flywheel and uprated single-plate clutch are installed, as is a new lower ratio limited slip differential featuring carbon clutches.

Lighting

At the front a fully bespoke headlight system was developed to take advantage of the latest in LED technology.

The entire lighting bucket is constructed from a combination of lightweight forged T-6061 aluminium components and carbon fiber to accommodate the larger Bi-LED projectors and active day time running lights. The assembly is encased in a beautiful hand-polished aerospace grade glass housing, taking inspiration from the original design elements.

Body

To initiate the restoration process, Gunther Werks uses a convertible as a foundation and restores the chassis to accommodate the heightened performance. Unlike the typical reduction of torsional rigidity that comes with removing the roof, Gunther Werks has taken significant measures to prevent such side effects. The chassis restoration process begins by revamping the factory components that our coupes also undergo, but with additional enhancements. Upgrades are added to the space previously occupied by the rear seat compartment of the coupe, and a new roll cage and roll hoop are integrated to provide support for the new tonneau cover. These measures not only enhance occupant safety but also contribute to further strengthening the chassis.
