Rennline Tuneable Semi-Solid Engine Mount 


Rennline Tuneable Semi-Solid Engine Mount is the ultim
ate upgrade for Porsche 718 owners seeking improved performance, precision, and adjustability. Designed to replace the compliant factory rubber mounts, this system dramatically reduces unwanted engine movement, delivering sharper acceleration, enhanced handling, and a significantly improved shifter feel.

Perfect for both street and track use, this is a versatile, fully tunable solution that allows you to configure your Porsche’s performance exactly the way you want.

Key Features

  • CNC Machined Billet Aluminium Construction – built for strength, precision, and durability.
  • Tuneable Inserts – includes three pairs of polyurethane inserts in different densities:
    - Yellow (65A) – softest, for daily driving comfort and reduced slop.
    Blue (75A) – balanced stiffness for aggressive street and light track use.
    Red (85A) – stiffest, designed for full race applications.
  • Nine Possible Combinations – mix and match inserts to fine-tune mount stiffness for your driving style.
  • Improved Driving Feel – reduces engine slop, prevents missed shifts, and increases drivetrain responsiveness.
  • Street or Track Ready – softer inserts preserve comfort, while stiffer ones maximise control under racing conditions.

Why Replace Your Factory Engine Mounts?

Factory Porsche engine mounts use compliant rubber that softens over time, causing:

  • Excessive Engine Movement – leading to sloppy acceleration and handling.
  • Reduced Shifter Precision – missed shifts or vague gear changes. 
  • Inconsistent Performance – especially under high load or during spirited driving.

Upgrading to the Rennline M143 semi-solid mount eliminates these issues, transforming your Porsche with sharper responses, stronger acceleration, and improved driver confidence.

Benefits of the Rennline M143

  • Customisable Performance – nine stiffness options let you tailor comfort and control.
  • Motorsport-Inspired Design – ideal for both road cars and dedicated track builds.
  • Enhanced Longevity – billet aluminium body and durable polyurethane inserts last far longer than factory rubber.
  • Confidence in Every Drive – Rennline products are built by Porsche enthusiasts for Porsche enthusiasts, ensuring quality and excellence.

Upgrade your Porsche 718 with the Rennline M143 Tuneable Semi-Solid Engine Mount – the most adjustable, performance-focused mount available, giving you the freedom to tune your car for the street, the track, or anywhere in between.
