Track Density Line

We're proud to announce the availability of the Street Density Line Transmission Mounts for B5 and C5 Chassis Audi and B5 Chassis Volkswagen models!

034 Motorsport's Density Line Mounts are the new standard in comfort and performance. Our mounts are redesigned with performance in mind, and manufactured from high-durometer rubber for increased performance and durability, without sacrificing comfort. Density Line Mounts are void-free and fluid-free, eliminating the slop associated with the factory mounts.

Street Density:

The Street Density Transmission Mount is manufactured from 50 durometer rubber, which is approximately 20% stiffer than stock. The mount bases are made from steel, and are much stronger than the factory aluminum ones, to cope with the added stress of spirited driving.

The result is greatly reduced drivetrain slop, crisper shifting, and minimal wheel hop, without any significant increase in noise, vibration, or harshness (NVH) inside of the cabin. These mounts are a completely re-engineered performance solution, not just inserts for use with the factory mounts.

Track Density:

The Track Density Transmission Mount is manufactured from 80 durometer rubber, which is approximately 90% stiffer than stock. The mount bases are made from steel, and are much stronger than the factory aluminum ones, to cope with the added stress of spirited driving.

The result is a locked-down drivetrain, solid shifting, and virtually no wheel hop. Track Density Mounts will cause a noticeable increase in noise, vibration, and harshness (NVH) inside of the cabin.

Features:

  • Manufactured from 50 Durometer (Street Density) or 80 Durometer (Track Density) Rubber with Void-Free Construction
  • Reduced Drivetrain Slop
  • Decreased Transmission Movement Under Load
  • More Direct Power Transfer
  • Improved Shifting Feel
  • Complete Drop-In Replacement of Factory Transmission Mounts
  • New Installation Hardware Included
  • Sold Individually (One Vehicle Requires 1 or 2 Mounts, Depending on Application)

Warranty:

  • 1 Year Limited Replacement Warranty (If you encounter any issues with our products outside of the warranty period, we will work with you to provide a resolution.)
High-Durometer Rubber vs. Polyurethane:

Density Line Mounts are manufactured from high-durometer rubber instead of polyurethane for a number of reasons. While vulcanized rubber mounts are more expensive to prototype due to increased complexity of manufacturing and high initial tooling costs, rubber is inherently better than polyurethane as a damping medium for mounts and bushings.

Rubber is able to deal with stress under both tension and compression, while polyurethane mounts rely on the damping medium to be effective only under compression. Rubber is also excellent in shear, where polyurethane is ineffective, making it ideal for applications that apply a shear force to the bushing during articulation.

Rubber does not pack and wear like polyurethane does, which ultimately results in a long-lasting part with consistent performance and comfort.

Street Density vs. Track Density:

We recommend Street Density Mounts for all daily-driven vehicles. They offer a significant increase in performance with a minimal increase in NVH transfer into the cabin. Track Density Mounts are recommended for purpose-built track cars, or those who do not mind significantly increased drivetrain noise and vibration in the cabin.

Please select Street Density or Track Density from the dropdown menu above. 

Sold individually. One vehicle will require 1 or 2 mounts depending on application! 

Note: Only fits passenger side of manual transmission 1.8T cars.  Driver side mount for manual 1.8T cars available here.  Please visually verify your application before you order.

Most comfortable office chair this fluffy guy has ever sat in.
Color: Black, Style: Classic
This chair is incredibly comfortable—easily the most comfortable one I’ve ever sat in. At around 300lbs, I’ve struggled to find a chair that’s both supportive and spacious. Most options feel tight, with the armrests pressing into my hips. Not this one. If anything, I feel small in it—there’s plenty of room on either side. It’s like going from a cramped budget airline seat to first class on a full-service carrier. The lumbar support is the best I’ve ever used. The materials are top-notch—everything from the base to the legs to the casters is metal (feels like steel). The casters themselves use what look like inline skate wheels and glide effortlessly across carpet—almost too well on hard surfaces, so you might want to consider a rug. Not a flaw, just something to keep in mind. I’ve paid twice as much for chairs that felt half as good, so in my opinion, this is an excellent value. The faux leather looks great and the stitching appears durable. While it may not last as long as real leather or high-quality fabric, it should hold up for a reasonable amount of time. Tilt functionality is basic—just two settings: upright or slightly reclined. Honestly, that’s all I need. If you’re looking for something to nap in, this might not be the chair for you. But for office work or gaming, it absolutely delivers all-day comfort. For reference, I’m 5'8", and the headrest aligns perfectly with the back of my head. If you're 6'5", it might end up being more of a neck rest. And I have to give a special shoutout to the included T-shaped hex wrench. It may sound silly, but this alone earns it a 5-star review from me. Every other chair I’ve bought includes those awful angled hex wrenches that make you slam your knuckles into the frame with every turn—often accompanied by some colorful language. Sure, I have my own tools, but finding where my wife hid them isn't always easy. A good-quality tool in the box? That’s thoughtful and appreciated.

Wide and comfortable office chair
Color: Black, Style: Classic, Color: Black, Style: Classic
It's made of very fine leather and in good quality. It has a pump to pump air to the back of the chair, so I can adjust the softness of the chair back. It's a very wide chair. Maybe the widest one I ever bought. I can only sit half of its space. It's very easy to install, the alignments are perfect. Its arm and height is adjustable. The wheels are advance ones which make it move through the floor smoothly. It looks an advance chair if you want an upgraded experience.

Excellent Comfort and Great Value for a Home Office
Color: Elegant Grey, Color: Elegant Grey
I am extremely happy with this office chair and feel it offers excellent value for the price. The chair was easy to assemble, and all the parts fit together perfectly. Once assembled, it feels sturdy, stable, and well-made. The high-back design provides outstanding support for my back, neck, and shoulders. The seat cushion is thick and comfortable, making it easy to sit for long periods while working, studying, or gaming. The padded headrest adds extra comfort, and the faux leather material looks stylish and gives the chair a premium appearance. One of my favorite features is the flip-up armrests. They are comfortable to use and make it easy to slide the chair under my desk when I need extra space. The height adjustment, smooth swivel, and rocking function all work well and allow me to find the perfect sitting position throughout the day. The chair arrived exactly as described and exceeded my expectations in both comfort and appearance. It looks great in my home office and has made long work sessions much more enjoyable. If you're looking for a comfortable, attractive, and affordable office chair, I highly recommend this product. I would definitely purchase it again and would gladly give it five stars.

Comfortable and Stylish Office Chair
I’ve been using this chair for my home office, and it’s been very comfortable. The high back provides good support, and the lumbar support helps reduce strain during long hours at my desk. The leather looks nice and gives the chair a professional appearance. I really like the flip-up armrests because they make it easy to slide the chair under the desk when not in use. The rocking function is a nice feature for relaxing during breaks, and the chair rolls and swivels smoothly. Overall, it’s a comfortable, well-made office chair that looks great and provides excellent support for everyday work.

Excellent lumbar support and easy assembly
I bought this chair because of my lower back pain, and it has been very comfortable to use. The leather feels soft, and the lumbar support is excellent. Assembly was easy, and the tools included, especially the screwdriver design were very well thought out, which made the whole setup process much easier.
