Key Features

• Bilstein B6 Performance series strut assembly
• Monotube internal design for consistent damping response

• Yellow painted finish with blue bellows boot included
• Upper stem mount and lower base cup mount configuration

Product Details

Bilstein B6 Performance dampers are built as a performance-focused replacement for factory dampers while retaining the OE spring. This front left strut assembly is designed for the Mini Cooper platform and uses Bilstein’s monotube construction to help deliver more controlled handling and improved road feel. The yellow finish and blue bellows boot identify the B6 Performance line, while the part number 35-103233 helps confirm the correct application during ordering.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Compatible with 2003-2008 Mini Cooper, front left, and 2002 Mini Cooper, front left from 3/2002.

What It Helps Address

• Excessive front-end bounce or float
• Reduced steering response in the Mini Cooper front suspension
• Worn OE strut damping performance
• Uneven control over bumps and road transitions
• Loss of stability during cornering and braking

Installation Notes

Install on the front left position only and verify vehicle build date for 2002 Mini Cooper models, since this application applies from 3/2002. Reuse the OE factory spring as specified for the B6 Performance design, and confirm the upper stem and lower base cup mounting style before installation. Always compare the existing strut, mounts, and fitment details against part number 35-103233 before assembly.

Quality Assurance

Bilstein tests each damper to meet or exceed OE standards, supporting consistent performance and fitment confidence. The B6 Performance line is built for drivers who want a controlled suspension upgrade without changing the factory spring setup.
