034Motorsport Street Density Front Upper Strut Mount Pair for Audi A3, S3, RS3, TT, and Volkswagen Golf, GTI, Golf R (2014–2024)

The 034Motorsport Street Density Strut Mount is a front upper suspension strut mount, sold as a pair, that replaces the factory mounts on Audi A3, S3, RS3, and TT and Volkswagen Golf, GTI, and Golf R models. Each mount uses high-durometer rubber fully vulcanized to the center cup, so the cup cannot shift inside the rubber the way it can in a factory mount. The steel mount body has been redesigned to handle the added stress of spirited driving. Strut mount deflection is reduced, which helps the front suspension hold proper geometry under load and sharpens steering feel. 034Motorsport describes these as completely re-engineered mounts and a direct drop-in replacement for the factory parts, not inserts that go into the stock mounts.

034Motorsport parts sold by PMB carry a 24-month parts warranty.

The factory strut mount used on these cars was an improvement over earlier generations, but its low-durometer rubber lets the steel center cup move once performance dampers or coilovers are fitted. Owners often hear a squeak from the front mounts when pulling out of driveways, crossing speed bumps, or rolling slowly over uneven pavement, and these mounts are built to eliminate that noise. The Street Density line comes in two rubber hardnesses. The 60-durometer version is the OEM+ choice, with slightly more noise, vibration, and harshness (NVH) than factory mounts and little effect on comfort. The 70-durometer version is stiffer for further reduced deflection and more precise steering under heavy load, at the cost of more cabin NVH. 034Motorsport chose vulcanized rubber over polyurethane because rubber damps under tension, compression, and shear, and it does not pack down and wear the way polyurethane can. Strut mounts sit at the top of each front strut, carrying the strut into the body and isolating road shock from the chassis.

Common Questions

Will these stop the squeak from my front mounts after fitting coilovers?
Yes. The squeak comes from the steel center cup moving in the soft factory rubber, and vulcanizing the rubber to the cup eliminates that movement.

How much harsher will the ride feel?
The 60-durometer mounts add only a minimal increase in cabin NVH compared with factory mounts and keep comfort close to stock.

Do I get one mount or two?
Two. These are sold as a pair to cover both front struts.
