A Range Built for Precision
Hardrace’s catalogue spans every corner of the chassis and suspension spectrum. From front strut braces that stiffen the bulkhead to anti-roll bar links that sharpen turn-in, each component is engineered to exacting standards. Key offerings include:
- Front and rear strut braces
- Adjustable control arms and toe arms
- Anti-roll bar end links
- Performance transmission and differential mounts
- Polyurethane and rubber bushes
- Sway bar brackets and lowering arm kits
Each item allows for geometric tweaks to camber, caster and track width, so you can tailor your car’s personality to your own driving style.
The Art of Geometry Adjustment
Fine-tuning suspension geometry isn’t just for race cars. Small changes to camber or caster can sharpen turn-in, improve tyre wear or restore factory handling after lowering. Hardrace components feature slotted mounting points, eccentric inserts or threaded adjusters, giving you control over:
- Camber angle for grip optimisation
- Caster for steering feedback and high-speed stability
- Toe for turn-in response and straight-line tracking
Whether you’re chasing milliseconds on circuit or seeking a planted feel on B-roads, these tweaks let you strike the ideal balance.
Hardened Rubber vs Pillowball: Making the Right Choice
When upgrading chassis or drivetrain mounts, you’ll often choose between hardened rubber and pillowball (PTFE-lined) options. Here’s how each stacks up:
|
Feature |
Hardened Rubber |
Pillowball (PTFE-lined) |
|---|---|---|
|
NVH (Noise, Vibration) |
Excellent absorption |
Transmits more noise and vibration |
|
Durability |
Good resistance to cracking under load |
Superior longevity under high loads |
|
Precision and Feedback |
Some compliance under cornering forces |
Near-instantaneous chassis feedback |
|
Maintenance |
Largely maintenance-free |
Requires occasional lubrication |
|
Price Point |
Generally more affordable |
Higher cost due to PTFE inserts |
Pros and Cons
Hardened Rubber
- Absorbs drivetrain buzz and road harshness
- Reduces resonance in the cabin
- Slightly flexes under heavy cornering
Pillowball
- Minimises deflection for sharper response
- Wthstands repeated high-load cycles
- Transmits more road and engine noise
Choosing the right mount depends on your priorities. If you favour comfort and a quieter cabin, hardened rubber is the way to go. For track-focused builds or those craving instant feedback, pillowball mounts deliver precision at the cost of added noise.
