"Best" motor mounts

Density Line Mounts:

034Motorsport's Density Line Mounts represent a high-quality, budget-friendly upgrade for engine mounts, utilizing rubber with a higher durometer compared to original equipment. In contrast to factory mounts that typically contain fluid or have voids, our mounts are constructed from solid rubber. This design helps to eliminate the risk of collapse and enhances overall performance. Additionally, the metal composition of Density Line Mounts has been improved; they are manufactured from steel rather than aluminum, minimizing the chance of cracking or separation, which can be frequent issues with factory mounts.

Next, I'm considering upgrading the rear diff mount with the $40 Apikol version since I've started to notice some knocking noises as everything else has become more rigid.

If comfort is your priority and you're not going for extreme power, I would suggest sticking with an OEM fluid-filled mount. Just my two cents.

I've experienced various mount configurations through both driving and riding in different vehicles, and I personally run the Street Density mounts due to my belief that they're the best motor mounts for daily-driven vehicles.

Here is a cutaway illustration that highlights what differentiates our Density Line Mounts from factory and OE replacements. While the external appearances may be similar, the performance and durability stem from the materials and design utilized internally. Since we recognize that you cannot dissect your brand-new mounts to evaluate their construction, we have provided a concise comparison between a factory B5 Audi S4 mount and our Street Density mount. Our mounts feature solid rubber as a superior damping medium, and even drivers who are particularly sensitive to NVH have found satisfaction with the Street Density option.
