Cette catégorie couvre les modèles 2006, 2007, 2008, 2009 Cadillac STS-V.
Technical Specifications: Cadillac STS-V
LC3 Powertrain: The engine is a 4.4L supercharged V8 utilizing a reduced bore diameter compared to the standard 4.6L Northstar to increase cylinder wall thickness. It employs a 2.0L Roots-type supercharger generating 12 psi of boost, integrated with a laminar-flow intercooler.
Drivetrain & Chassis: The engine is positioned lower in the frame to accommodate the 6L80 6-speed automatic transmission. The chassis utilizes a high-ratio steering rack and a Brembo braking system consisting of 355mm front and 365mm rear rotors with 4-piston calipers.
Mechanical Interface: The vehicle uses a six-lug hub pattern to manage torque loads, departing from the standard five-lug passenger car configuration. It features a staggered wheel fitment with 18x8.5-inch front and 19x9.5-inch rear alloy wheels mounted with Pirelli run-flat tires.
Thermal Management: The cooling system includes a dedicated heat exchanger for the supercharger's liquid-to-air intercooler and an external engine oil cooler to maintain thermal stability during high-load operation.
