The Rennline Tune-able Engine Mount for the 964, 993, 996, and 997 offers the ultimate in adjust ability for your car.

Our mounts are CNC machined from billet aluminium and include three pairs of inserts in varying densities. Tune your mounts by using the softer inserts to reduce engine slop and avoid missed shifts in your street car, or utilise the stiffest inserts to get the most from a more focused track car.

Here at Rennline we know you want your Porsche to be flawless, and that is why we are Driven to Improve Excellence.

Fits:

With factory hydraulic engine mounts, the drive train will move independent of the chassis during acceleration and cornering loads. This movement can upset the balance of the vehicle and create negative handling effects.

RSS Tarmac Series Performance Engine Mounts minimise these effects by utilising specialised polyurethane bushings which offer a firmer, more direct driving feel with optimum feedback. This upgrade will not adversely effect ride quality or cause knock sensor issues commonly associated with solid engine mounts.

Solid engine mounts are a smart upgrade to any track or aggressive street car, and were installed on Porsche factory race cars. Stock mounts are made of compliant rubber, and contribute to imprecise shifting and inferior throttle response. Solid mounts create slightly more interior vibration than rubber mounts, but securely connect the engine and transmission assembly to the car's unibody, creating a crisper throttle response and shifter feel. Rennline's solid mounts are CNC machined from 6061 aluminum for strength and light weight, and come as a pair with new Grade 8 mounting hardware. Sold as a set of (2)

About Engine Mounts

Engine mounts, also called motor mounts, are critical components of your Porsche, securing the engine to the chassis and absorbing vibrations during operation. Traditionally, rubber has been the go-to material for these mounts, but polyurethane is gaining popularity due to its enhanced performance and durability compared to rubber.

Polyurethane motor mounts excel at absorbing vibrations, ensuring a smoother and quieter ride, benefiting both driver and passengers. Although they are initially more expensive than rubber mounts, their longer lifespan makes them more cost-effective over time, reducing maintenance and replacement expenses.

In high-performance vehicles like Porsches, motor mounts face extreme stress, vibrations, heat, and pressure. Uprated polyurethane motor mounts provide additional benefits by limiting engine movement, enhancing engine stability during acceleration and gear shifts, and offering improved gear engagement, thus protecting gearboxes and shafts.
