AST Lowering Springs- BMW M5 Competition (F90) Engine:Standard Maximizing flow in the constraints

Maximizing flow in the constraints of the factory engine bay is the result of the turbo inlet size and shape

SmartSeal clamps and heavy-duty

Our engineering department use Computational Fluid Dynamics (CFD) software to optimize the end tanks and FDS system for minimum pressure drop and maximum flow

Centre pipe diameter: 65mm reducing to dual 50

Finishing off this exhaust system is a 4-1/2 IN diameter black 304 stainless steel clamp-on exhaust tip

AST Lowering Springs- BMW M5 Competition (F90) Engine:Standard Maximizing flow in the constraintsTransform your vehicles profile and performance with AST Lowering Springs. Engineered for drivers who demand a more aggressive aesthetic without sacrificing ride quality, these springs provide a significant reduction in ride height while working in perfect harmony with your factory dampers. By lowering the centre of gravity, AST springs reduce body roll during cornering and nose dive under heavy braking, resulting in a more stable and communicative
