Why coilovers get noisy
The complaint is almost universal on aftermarket suspension: the car gets sharper, and it also gets loud. Knocks over expansion joints, road roar through the strut towers, a general hardness that was not there on the factory setup.
The usual culprit is the top mount. Performance coilovers typically use a rigid or pillowball top mount for maximum feedback and precise camber adjustment. That rigidity is exactly what transmits Noise, Vibration, and Harshness straight into the cabin.
Most of the market treats this as an unavoidable trade: precision or refinement.
The isolator approach
Neotech's Anti-NVH top mount integrates a purpose-engineered rubber isolator into a camber-adjustable top mount. The isolator interrupts the structure-borne path into the strut tower while the mount retains its adjustment function.
Developed through a government-backed R&D program and now patent-registered, it delivers composure and road isolation that rigid mounts cannot reach — without giving up camber adjustability.
This is the right choice where daily comfort matters as much as precision: street cars, spirited road driving, and dual-purpose builds.
When to choose pillowball instead
For maximum response and raw feedback — dedicated track and competition builds where NVH is irrelevant — a pillowball top mount option is available.
