Meet KIA's one-off Stinger GT420 track car

By CARSIFU | 26 July 2019

LONDON: Kia has unveiled its latest track-going creation in the form of the Stinger GT420.

Other than its newfound livery, the standard Stinger has been internally gutted to save precious weight - even the car's battery was replaced with a lightweight lithium-polymer version to save 22kg.

Externally, the car has been fitted with a Stillen front splitter and rear diffuser as well as an Air Design rear spoiler.

Not to mention, its 3,342cc V6 twin-turbo direct-injection engine producing 365bhp and 510Nm has been tuned to output 422bhp and 560Nm of torque.

To help it achieve the power ratings, the engine has been fitted with HKS M45il spark plugs, K&N sports air filter, and a Milltek Sport quad-exhaust system with deleted catalytic-converters among others.

Also, a six-row replaces the standard four-row automatic transmission cooler before flashing the transmission software for quicker shifts in Sport and Sport+ modes.

The stripped interior had rear windows glued into place, lightweight door cards installed and the sunroof replaced by a steel panel before the underbody crossbars, roll cage, seats, belts and fire extinguisher was installed for a total weight savings of 150kg.

The wheels were replaced with wider and lightweight 19-inch OZ Racing Leggera alloys wearing 235/35 (front) and 265/30/R19 (rear) Pirelli Trofeo R tyres - and given negative 2.5-degree camber-angle after modifying the front cross-member.

All that partially hides the front Brembo six-pot callipers and racing steel flex pipes that bite down on the 380 x 34mm discs via Endless pads while the rears still use the Stinger's standard brakes and fitted with cooling ducts and deflectors

Tweaks were made to the anti-lock brakes, traction control and electronic stability control to take into account its added performance.

Additionally, in Sport+ mode traction control and electronic stability control off completely switched off to allow for drift duties.

The standard dampers were paired with Eibach Pro lowering springs along with front 25mm and rear 17mm (custom) anti-roll bars.
