Chassis No. IR 330039
This historically significant vintage racecar has recently undergone a complete mechanical and cosmetic restoration to the highest standards. It has been accepted to compete at the prestigious Monterey Historic Races where it was raced with distinction. It is equally at home on the racetrack, tour or concours. The car has current FIA and FIVA papers.

This Iso Rivolta is the one-off prototype Daytona commissioned by Carlo Bernasconi of Milan in 1965. It features similar specifications to the Iso Rivolta LeMans cars from 1964 which include Superleggera construction. The body was built on an Iso chassis by the famous Modena carrozzeria Neri e Bonaccini (Nembo) with technical assistence from Bizzarrini. The cars made their public debut at the Italian Grand Prix at Monza were it was greeted with great excitement.

The Daytona was conceived as a lightweight dual-purpose car.
Combining a lightweight aluminum body and sophisticated chassis with American power the Iso had incredible performance for the day. The engine is a Corvette V8 and driven through a close ratio four speed Corvette transmission to a Power-Loc equipped Salisbury differential. Front suspension is by double unequal length wishbones and coil spring/damper units. At the rear a de Dion axle is located by four-bar trailing arms and a Watts link with inboard disc brakes. Wheels are Campagnolo alloy knockoffs.

This car remained in the personal collection of Carlo Bernasconi until 1991when it was purchased by Binie William. The car was fully restored by the renowned Paul Lanzante, in England. Since its restoration it has competed in a number of vintage events winning the 1997 Italian National Hill Climb Championship in the GT Prototype class as well as finishing 7th in the 6 hours of SPA in 2000.

The car was purchased in 2000 by an American collector who had a complete “ground up” cosmetic and mechanical restoration performed before the car competed at the Monterey Historic Races at Laguna Seca in 2004. The engine was completely rebuilt by Ron Shaver and a crossover Weber manifold with four 48 DCO 2SP carbs was added pushing the output to 490HP. A new T10 Transmission was installed and the Jag differential rebuilt. The engine and transmission have less than an hour of track time on them. Some tasteful cosmetic changes were also done at this time. At the front a hood scoop was added to feed cool air to the new Weber set up. Top fender vents, to aid ventilation to the driver, and a new side mirror housing were added. In the interior the roll bar was re-designed and hidden. New tan leather upholstery was installed along with additional gauges on the dash. The side windows were changed form sliding to a pull up system typical of the period.

Canepa Design Upgrades
The suspension of this car has been completely engineered, aligned and corner weighted. New 9” wide Campagnolo rear wheels were installed running Good Year Blue Streak 600x15 tires. The suspension has been lowered via new fabricated adjustable spring perches to period correct ride height. New rear trailing arms with relocated shock mounts (to work with the new wider rear wheels) were fabricated along with new roller spline axles. Custom double adjustable Koni shocks were designed to work with the new spring rates and lower ride height. The rear suspension links and Watts link pick up points were optimized for the new ride height. On the front suspension the proper pre-load was set for all pivot points and keyed.

The Engine was Dyno-tuned, re-jetted and a full pre-race service performed. It produces 490HP and 434 ft Lb of Torque. The car has been track tested and is completely race ready, it’s lap times are now competitive with 289 Comp Cobras and Corvettes. The car comes with a complete second set of wheels and tires.

About Iso Rivolta
The Iso Rivolta Company was established in 1939 when Renzo Rivolta purchased a small appliance manufacturing company in Genua Italy. They began producing small motorcycles and car shortly there after. Piero Rivolta took over the Iso Company after his father passed away in 1966. One of the first things he did was the introduction of a new version of the Grifo, the Targa, and of a whole new car, the Iso S4. After Iso closed in 1974 he went to America and formed the Rivolta Group. He surprised the automotive press with the introduction of the Grifo 90 in 1992 but it remained a one-off. Today the Rivolta Group is busy in many area's, yachts & boats, design in cooperation with Zagato Italy, architecture & project developing etc. and the Isigo microcar.
