Ferrari 985803904

The Compl Rear Tunnel Casting (SKU: fe-985803904) is an essential structural component for your Maserati’s chassis integrity. Proper installation ensures optimal weight distribution and drivetrain stability in high-performance conditions. Engineering excellence in structural design This precision-machined aluminum alloy casting forms the backbone of your Maserati’s rear subframe assembly. Engineered to withstand extreme torsional forces during aggressive cornering, it serves as the mounting point for critical components including the differential, suspension linkages, and exhaust system. The SKU fe-985803904 replaces outdated versions with improved thermal dissipation channels to protect adjacent carbon fiber elements. Performance-critical infrastructure In Maserati’s quadrifoglio models, this tunnel casting directly impacts: - Weight distribution balance (42:58 front-rear ratio preservation) - Exhaust resonance dampening in sport mode - Differential oil temperature regulation during track use Failure to replace worn castings risks chassis flex exceeding 0.15° tolerance, potentially compromising handling characteristics and necessitating full drivetrain realignment.
