The ZR1 model Corvette is 3" wider in the rear than a normal Corvette to fit the 11" wide rear wheels. The ZR1 was powered by a Lotus Engineering designed, 4 cam, 350ci, all aluminum LT5 V8, that produced between 375 and 405hp depending on the year of production. This white ZR1 was transformed into a 425hp ‘Callaway Supernatural’ in 1993. In 1994 Autobahn brought forth collaboration with Corvette Challenge winner, Doug Rippie Motorsports, DRM. This ZR1 further evolved with their DRM 500+ horsepower 368ci package. With different pistons, rods, fully ported heads and intake, camshafts, 11/1 compression and 18ci greater displacement. The suspension has fully adjustable coil overs with Bilstein computer controlled shocks, DRM anti sway bars, camber brackets, modified rear steering knuckles and anti dive geometry. Autobahn maintained and further developed the car over the next several years as it performed flawlessly in time trials and DE events. We have since converted this special ZR1 into a legal road car. Further enhancements include; 44 pass Aeroquip plumbed oil cooler, Canton cartridge oil filter, Redline lubrication, headers with high flow converters, weld in roll cage, modified seat with 5 pt harness, massive aluminum radiator, through the bumper ram air intake, Hella headlamps, Forgeline 17x9.5" and 17x11" rims. The Callaway front Brembo brake system has been replaced with the even larger Wilwood Nascar 6 piston front calipers with alloy hats fed by 3" air hoses for cooling, the front brake calipers have been drilled, reinforced and installed on the rear, stainless steel -3 brake lines are used with Castrol SRF fluid. 20 lbs has been reduced from the stock flywheel weight and a Centerforce Dual Friction clutch engages the 6spd ZF transmission. Ignition is handled by coil packs and Magnecor wires. Plenum insulators, modified throttle body, Samco hosing, high pressure air diverters in front of the wheel openings, ect. With air conditioning and adjustable ride stiffness, this Vette is perfect for long distance road travel, auto crossing and lots of smiles. Magazine shootouts of this DRM 600/510 engine package on street tires yielded:
12.0sec/119mph 1/4mile, 4.2sec 0-60, 190+mph top speed. Braking performance of 60 to 0 in 102 feet and 80 to 0 in 200 feet. Good even by today’s high performance standards this was particularly outstanding in its era for a full weight road car.
Car magazines in 1990 dubbed the then new ZR1 Corvette, " King of the Hill".
