Bilstein 34-030066 Suspension Strut Cartridge - Front

Bilstein B8 Performance Plus Front Strut Cartridge

The Bilstein B8 Performance Plus front suspension strut cartridge is a performance upgrade for OE dampers when paired with aftermarket lowering springs. Built with a monotube internal design and application-specific valving, it is aimed at sharper handling response and a lower, sportier stance on select Audi models.

Compatible With 1980-1998 Audi 4000, Coupe, 80, 80 Quattro, 90, 90 Quattro, Coupe Quattro, and Cabriolet front suspension applications that use a 50mm outside strut diameter where noted. Part number 34-030066 is part of the Bilstein B8 Performance Plus line, which is engineered for lowered vehicles and tuned to work with spring setups that change ride height and suspension geometry.

Detailed Description

Bilstein 34-030066 is a front suspension strut cartridge for Audi performance and classic chassis applications. The B8 Performance Plus line is built to complement lowered ride heights by restoring controlled suspension movement after spring changes, helping maintain predictable front-end behavior during braking, cornering, and road transitions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Fits 1988-1991 Audi 90 Quattro, front. Fits 1990-1991 Audi Coupe Quattro, front. Fits 1980-1987 Audi 4000, front. Fits 1981-1987 Audi Coupe, front.

What It Helps Address

• Excessive front-end bounce after installing lowering springs
• Soft or inconsistent damping on aging OE struts
• Reduced steering response in lowered Audi suspension setups
• Uncontrolled body movement during cornering and braking
• Front suspension wear symptoms tied to worn strut cartridges

Installation Notes

Verify the front strut diameter and vehicle application before installation; several listed Audi models require a 50mm outside strut diameter. This is a suspension strut cartridge with a stem upper mount and housing lower mount, so it should be matched to the correct front strut assembly and lowering spring setup. Professional installation and a post-install alignment are recommended after suspension work.

Quality Assurance

Bilstein tests B8 Performance Plus dampers to quality standards that meet or exceed OE requirements. The monotube design and application-specific valving are used to support consistent performance across the listed Audi fitments, including Audi 80, 90, Coupe, Coupe Quattro, 4000, and Cabriolet front applications.
