Ferrari 348 Challenge Race Cars
The Ferrari 348 Challenge series was begun in 1993 in Europe and
brought to North America in 1994. This was a single marquee
gentleman's race series for amateur owner/driver's.
The original series used converted street cars.
In North America the original cars were converted
348 Serie Speciale model's, but any 348 1989 and up that was
brought up to 348 SS spec could be used.
In Europe any TB/TS and GTB/GTS could be converted, but
no Spiders were allowed.
An additional challenge kit was installed requiring 110 man hours.
The kit included a full roll cage, OMP racing seats, 2" four point
harness (replaced with 3" six points harness in '95), fire
extinguisher (some installed plumbed in system instead),
battery disconnect, and plexiglass for the front fog lights.
(later the signals assembly was removed in place of
brake duchs) New under trays were fitted front and rear with
brake cooling ducts. The original series used stock 17" rims
mounted with slicks. These were upgraded to 18" Speedline
magnesium challenge rims in 1995.
Additional modifications were allowed including upgraded
ECU with 7800 rpm redline (stock 76 rpm) advancement of timing
to preexisting holes in drive pulleys, improved fuel pumps,
and lower 1st and 2nd gears.

with stock cats. Racing brake pads and "Aeroquip" type brake
hose were also supplied by Ferrari.
The ABS was allowed to be disabled, but not removed.

but not the compressor. Stiffer springs and differentdampers were
