AST Suspension ACU-B1401SD 5100 Series 1-Way Adjustable Coilover Kit Mini Cooper R50/R52/R53

The AST Suspension 5100 Series coilover kit delivers race-proven performance for 2002-2007 Mini Cooper R50, R52, and R53 models.

The 5100 Series shock absorbers utilize inverted (upside down) technology, which is race-proven and produces an extremely strong damper, providing better suspension geometry under heavy lateral and braking loads. The monotube design offers a large piston to control the adjustability of rebound damping, and eliminates aeration or foaming, resulting in more responsive valving.

Key Features:

• 12 distinct adjustment positions, each delivering distinct feedback and a unique driving experience
• One-knob rebound adjustment and adjustable ride height platform
• Front and rear dampers utilize coilover design and include springs designed to run OEM top mounts
• Shock bodies specially designed to maintain maximum stroke even with lowered ride height
• Rebuildable dampers serviceable at certified AST service centers

This kit includes front and rear coilover assemblies with springs, designed to work with your factory top mounts. The inverted rear damper design provides easier access to adjustments.
