Cobb Tuning Rear Engine Mount for FL5 Type R/DE5 Type S

COBB Tuning Rear Engine Mount - FL5 Civic Type R & DE5 Integra Type S

On a front-wheel-drive car making the kind of power the FL5 Civic Type R and DE5 Integra Type S make, the rear engine mount has one of the hardest jobs under the hood. The engine and transaxle want to rock backward every time you get on the throttle and forward when you lift, and the rear mount is what resists that rocking. Honda and Acura use a soft rubber mount here on purpose, because soft rubber soaks up vibration and keeps the cabin quiet, but that softness lets the whole drivetrain pitch under load. You feel the cost of that as wheel hop off the line, a split-second of slack before power actually reaches the ground, and traction that breaks loose when the engine lurches instead of staying planted. The COBB Rear Engine Mount firms that connection up so the drivetrain stays put, the power gets to the pavement cleaner, and the wheel hop goes away.

What you feel from the driver's seat is a car that hooks up harder and responds more immediately. Launches are more consistent because the engine isn't loading up and snapping back, shifts feel tighter because the drivetrain isn't taking up slack between gears, and hard corner exits put the power down instead of chattering the inside tire. On a FWD platform where getting the power down is the whole battle, controlling engine movement is one of the most effective things you can do, which is exactly what this mount is for.

A Dual-Durometer Design Tuned for NVH

The honest trade-off with any stiffer engine mount is NVH, meaning noise, vibration, and harshness. A fully solid or stiff poly mount will control movement beautifully and then rattle your teeth out at idle and buzz through the cabin at cruise. COBB's approach avoids that extreme by using two different bushing hardnesses in one mount: an 85A durometer front bushing and a 68A durometer rear bushing. Durometer is just a measure of how firm the rubber is, where a higher number is harder, so the firmer 85A bushing resists the main acceleration load and pins the engine down, while the softer, more compliant 68A bushing absorbs vibration in the other direction. The result is a mount that cuts engine movement and wheel hop well beyond the stock piece while keeping NVH livable for a street-driven car.

To be straight about it, this is still a performance mount, so you will notice a bit more vibration and engine sensation than the soft factory rubber, especially at idle. That's the nature of tying the drivetrain down more firmly, and it's a fair trade for the traction and response you get back. What COBB's durometer tuning buys you is that it's a noticeable improvement without the harshness that makes a stiffer mount miserable to daily.

Billet Construction, and Serviceable

The main body is machined from 6061 billet aluminum and finished in satin black anodizing to protect it from wear, with a subtle laser-etched COBB logo on each side rather than loud branding. The bushing sleeves and retaining caps are zinc-plated steel for durability. The detail that sets this apart is that it's built to be serviceable: the bushings are designed to be swapped, so down the road you can change to a different durometer if your priorities shift, whether that's firming it up further for track use or softening it back toward comfort. You're not throwing the whole mount away to change its character, which is rare in this category.

Install

This is a direct bolt-in replacement for the factory rear engine mount, no cutting or modification. As with any mount, work on a supported engine and torque everything to spec on reassembly.
