In addition to body shell alterations, Subaru’s machine for the 2003
WRC season featured a newly designed over-sized rear wing with four
vertical fins for the realization of superb aerodynamics. The 2003
machine also featured various internal modifications such as
improvements in engine and chassis durability to achieve an overall
increase in performance over the previous year’s machine. Subaru’s
Tommi Mäkinen took second place in the second event of the WRC season,
the
Sweden
rally, and expectations remain high for top performances in upcoming events.
Based on the powerful TGS chassis
The TGS chassis employs a resin monocoque frame with
aluminum die-cast power train deck. The underside of the power train
deck features air intake leading to engine fan for proper air
diffusion. ACS (Active Cooling System) is effective in the prevention
of engine over-heating. R/C electronics are encased in a special box
for protection. The TGS chassis is equipped with a high-performance
FS-12SS engine (2.11cc) that boasts superior air-intake and powerful
running. The TGS chassis also features 4-wheel double wishbone
suspension to realize excellent road-holding. Shaft driven 4WD affords
high reliability. Front and rear gear cases are both precision fitted
for smooth-running differential gears. With the cutting-edge EXPEC
wheel and trigger type transmitter provided, users can expect excellent
control.
