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

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

they will not fit on early 058 engine blocks found in B5 A4 and B5 Passat models

The kit does not vent to atmosphere (VTA) — making it emissions compliant and track legal

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
