Street 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)

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.

Clinician and client reference in Somatic Therapy
Format: Paperback
This book is written as an office reference. Part of this book is dedicated at the clinical level towards the professional. The book has somatic techniques for the professional with explanations. It helps the professional understand the work and identify things while working with the client. Then part of this book is written with patient hand out materials and exercises. Those sections are similar to what one would see for a client workbook.

Looks like it will be helpful
Format: Audiobook
I'm not very far into this one yet, but so far, I love it. I bought the kindle and audible versions. It is nice to be able to listen to the exercises to go through them, and to be able to look up the specifics of any exercise. With whisper sync, I can point to an exercise in the kindle, and have audible read it to me. Great. the exercises I have tried so far seem like they are going to be helpful.
