SuperPro Suspension Explained: Polyurethane Bushes & Control Arms

3 Kasım 2026

Automotive manufacturers design factory suspension with two main priorities: keeping production costs down and isolating the cabin from road noise. To achieve this, they utilize soft, voided rubber bushes that flex heavily under load. While this makes for a quiet daily commute, it completely ruins the steering precision and handling dynamics of a performance vehicle.

SuperPro is an Australian manufacturer renowned globally for solving this exact problem. With decades of experience in hardcore automotive engineering, SuperPro specializes in manufacturing premium polyurethane bushings, complete alloy control arms, and heavy duty anti roll bars.

Engineered and rigorously tested in some of the harshest real world conditions on the planet, SuperPro components are designed to vastly outperform standard rubber. They deliver massive improvements in handling, stability, and tyre life, all while maintaining a highly refined ride quality that does not ruin your daily commute.

The Problem with Factory Rubber

When you throw your car into a corner or hit the brakes hard, the forces acting on the suspension are immense. Standard rubber bushes compress and deflect under this weight. This deflection causes "dynamic alignment change", meaning your meticulously set wheel alignment shifts under load, causing the tyres to roll over onto their sidewalls and scrub speed. Furthermore, factory rubber perishes rapidly when exposed to track temperatures, engine oil, road salt, and harsh chemicals.

Upgrading to SuperPro polyurethane eliminates this deflection. By holding the suspension geometry perfectly rigid under extreme loads, the tyre contact patch remains flat on the tarmac, providing maximum grip and drastically extending your tyre life.

The SuperPro Polyurethane Difference

A common misconception in the tuning world is that fitting polyurethane bushes will make your car ride like a shopping trolley. While cheap, poorly cast polyurethane will cause massive cabin vibration and harshness (NVH), SuperPro is entirely different.

Advanced Material Blends: SuperPro formulates their polyurethane to provide the mechanical precision of a solid motorsport mount, but with the built in compliance required to absorb sharp road impacts. You get the handling of a track car without the teeth rattling ride.
Extreme Durability: SuperPro polyurethane is inherently resistant to wear, heat, UV degradation, and automotive chemicals. Fit them once, and they will likely outlast the rest of the vehicle.
Free Pivoting Design: Unlike rubber bushes which physically twist and tear as the suspension travels, SuperPro bushes are engineered to pivot smoothly around a central stainless steel crush tube. This eliminates suspension binding and allows the dampers to work exactly as intended.

Complete Control Arms & Anti Roll Bars

Pressing old, rusted rubber bushes out of factory suspension arms is a miserable, time consuming job. To make upgrading seamless, SuperPro offers highly engineered complete hardware replacements.

Alloy Control Arms (Supaloy): SuperPro manufactures complete replacement lower control arms crafted from lightweight, high strength alloy. These arms come with the premium polyurethane bushes already pressed in. More importantly, they often feature built in geometry corrections, adding crucial degrees of positive caster and negative camber to drastically sharpen steering turn in and eliminate understeer.
Anti Roll Bars (Sway Bars): To stop your car rolling through the corners, SuperPro anti roll bars are manufactured from premium spring steel. They tie the left and right sides of the suspension together, forcing the chassis to stay flat and planted during high speed directional changes. Paired with their heavy duty adjustable drop links, you can completely dial out factory body roll.
