Tarmac Rocket

Purpose-built for alpine hill climbs, the Tarmac Rocket excels on fast, technical asphalt courses with sweeping corners and elevation changes. Its ultra-wide stance and sticky Michelin Pilot Cup 2 tires provide mechanical grip that inspires confidence at the limit, while the aerodynamic package ensures stability and downforce to carry high speeds through complex bends and straights alike.

Carbon-kevlar widebody overfenders +180mm per side
Redesigned carbon fiber hood with bi-plane vents
Active rear hatch airbrake panels
Integrated rear diffuser extended by 150mm

Large fixed two-level GT-style carbon fiber wing with adjustable angle
Vented hood for heat extraction and front lift reduction
Active rear airbrake panels
Extended rear diffuser

Aerodynamics are integrated with function-first precision, featuring a vented carbon hood that reduces front lift through hot air extraction and a large fixed two-level GT wing with adjustable angle for tailored downforce. Active rear airbrake panels work in concert with a 150mm extended diffuser to maximize stability and braking performance, ensuring the Hellcat remains composed and balanced during rapid deceleration and high-speed cornering.

19x12 forged OZ Racing Rally wheels
Michelin Pilot Cup 2 tires 345/30ZR19
Ultra-wide 345mm tire fitment front and rear
Low-profile track-focused rubber

Custom forged 19x12 OZ Racing Rally wheels provide the perfect balance of lightweight strength and toughness needed for aggressive hill climb use. Wrapped in 345/30ZR19 Michelin Pilot Cup 2 tires, the setup maximizes contact patch and mechanical grip, allowing the Hellcat to plant its considerable power efficiently while maintaining precise steering feedback.

The stance is aggressively low and wide, with a ground clearance of just 75mm and a pronounced -4° camber front and rear. This geometry enhances cornering grip and tire contact during high-speed transitions, giving the Tarmac Rocket a planted, purposeful posture that reflects its hill climb intent without sacrificing street legality.

Supercharged 6.2L Hellcat V8
Upgraded intercoolers
Carbon intake manifold
Fully custom ECU mapping for hill climb power delivery

At its core lies the supercharged 6.2L Hellcat V8, recalibrated with enhanced intercoolers and a carbon intake manifold to maximize power and thermal efficiency. The ECU has been fully mapped for aggressive throttle response and torque delivery tailored to the demands of rapid hill climb ascents, ensuring the engine remains cool and potent throughout extended high-speed runs.

The drivetrain retains the Hellcat’s robust rear-wheel-drive configuration, optimized with reinforced components to handle increased stresses from wide tires and aggressive cornering forces. Calibration focuses on delivering smooth, predictable power transfer with minimal drivetrain lash, critical for maintaining traction on variable alpine tarmac surfaces.
