This 1998 Ferrari F355 Challenge was originally campaigned by Ferrari of Washington and driven by Milka Duno from 1998-2001. Reported to be a factory-built racer, it is now on offer by the fourth owner who describes it as the best prepped and most successful Forza Challenge Club Racing 355 on the planet, noting that he has won nearly every race entered in the car since 2012 including two outright championships that year and again in 2014. Recently refreshed including a full rebuild of the factory engine and more, the car is offered in race-ready condition with an extensive spares package.

Featured in this month’s issue of Forza magazine as pictured in the gallery, the seller notes that the car has remained in a tight ownership circle since new, though the original Ferrari build documentation is no longer with the car. The only evidence of prior incidents is a replacement right rear quarter panel that has no provision for the factory Pininfarina badge, a relatively light repair that suggests the car has never been involved in any serious crashes.

Aero improvements include a raised F430 Challenge wing (original included separately) and a custom made carbon fiber front splitter that is attached directly to the chassis. Three sets of factory Challenge wheels are included—two black sets wearing used Pirelli slicks and one white set wrapped in Hoosier rain tires with one heat cycle.

Safety equipment is all up-to-date and legal according to the seller. Sale includes an AiM MXL datalogger system that’s integrated with a SmartyCam HD video system. A Coolshirt suit cooler remains installed under the front trunk lid, and though radios are not included the car is wired for a Motorola two way communication system. The original OMP passenger seat remains for ballast and to allow passenger rides during practice days.

Per CCR rules, race weight is 3,100 lbs. as measured with a 165 pound driver and ending race fuel on board. A recent, engine-out servicing included new piston rings, valve springs, gaskets, belts, plugs and more, the seller adding that the rings in particular made a noticeable difference in upper RPM range power delivery. All stock internally per race regulations, the car’s original F129 Dino 40 valve V8 displaces 3.5 liters and should be good for slightly more than the factory quoted 375 HP thanks to freer-flowing Fabspeed headers (originals are also included) protected by fresh, $2,000 Capristo heat shield blankets.

The car further benefits from a large spares package including extra brake pads, starters, alternators, both hard and soft factory spring sets as well as the aforementioned original wing, extra wheels, tires and OEM exhaust manifolds. Shocks are Moton ClubSports that are adjustable for both rebound and compression, and again the originals do come separately. The car’s original three-pedal, non-F1 6-speed is also stock, and a recent service saw fitment of a new throw out bearing. Now said to be fully race-ready and in even better shape than during its last championship win, the seller further notes that his reserve is less than the total cost of 2014’s maintenance records.
