KMAC Suspension Solutions: Precision Alignment Meets Race-Ready Handling
In the world of high-performance driving, every millimeter matters—especially when it comes to suspension geometry. Whether you're dialing in your setup for track days, autocross events, spirited canyon carving, or simply want the ultimate street performance, alignment precision is non-negotiable. That’s where KMAC Suspension Solutions steps in as a game-changer. KMac
Known globally for their robust, motorsport-grade components, KMAC has carved a niche as one of the few brands that focuses entirely on alignment adjustability—offering camber, caster, and toe kits designed to fine-tune your vehicle’s suspension beyond factory limitations. With applications across European, Japanese, and American vehicles, KMAC products bring race-level geometry control to your garage.
Let’s dive into how KMAC suspension solutions can transform your car’s handling, optimize tire wear, and help you extract every ounce of performance from your chassis—whether you're hitting apexes or daily commuting with a sharper edge.
What Makes KMAC Different?
Unlike many aftermarket brands that offer a wide range of performance parts, KMAC is laser-focused on suspension alignment systems. For over 50 years, the Australian company has pioneered adjustable mounts, control arm bushings, and bolt kits that allow for a level of geometry control typically reserved for professional motorsport teams.
What sets KMAC apart is their combination of:
On-car adjustability (no need for disassembly)
Camber, caster, and toe kits available for a wide range of vehicles
Bolt-in designs that retain OEM ride quality while adding adjustability
No-compromise engineering, including stainless steel hardware, anodized components, and patented adjuster mechanisms
Their kits are used by racing teams, performance shops, and enthusiasts around the globe who want race-level control without sacrificing streetability.
Why Alignment Adjustability Is Key to Performance
When it comes to handling, alignment is everything. Even the most advanced suspension components—coilovers, sway bars, performance tires—won’t perform at their best without the proper geometry. KMAC’s range of products allows for precise dialing of three critical angles:
Camber: The inward/outward tilt of the wheels (negative camber increases grip in corners)
Caster: The forward/backward tilt of the steering axis (positive caster increases high-speed stability and steering feel)
Toe: The angle at which the wheels point inward or outward (influences corner entry and straight-line stability)
Factory vehicles, even sports cars, have limited (or no) adjustability in these areas. Once you lower the car, change wheels/tires, or start driving harder, your stock alignment falls out of spec—leading to understeer, uneven tire wear, or twitchy handling. KMAC kits let you fix that—precisely.
KMAC Camber/Caster Plates
Perhaps KMAC’s most well-known products are their adjustable strut top mounts—also known as camber/caster plates. Unlike many traditional camber plates that only offer one-axis adjustability and require disassembly for adjustment, KMAC plates stand out for three reasons:
Dual Adjustability – Adjust both camber and caster independently.
On-Car Tuning – Make adjustments without removing the strut assembly.
OEM Ride Compatibility – Designed to work with both standard and coilover suspensions.
These plates are CNC-machined from high-grade billet aluminum, anodized for corrosion resistance, and use KMAC’s patented eccentric adjuster system—eliminating the need for fragile lock rings or multi-piece slider systems.
Whether you're building a BMW M3 track car or want your WRX to corner flatter, KMAC top mounts offer real-time, measurable improvements in handling dynamics.
Adjustable Bushings and Arms
KMAC also manufactures a wide range of adjustable control arm bushings and complete adjustable arms, particularly for rear suspensions—where camber and toe can wreak havoc on tire life after lowering a car.
Camber/Toe Bush Kits – Replace non-adjustable bushings in rear control arms with KMAC’s adjustable bushings, allowing up to ±2.0° of camber and toe correction. Ideal for lowered cars experiencing excessive inner tire wear.
Complete Arms – For platforms like the Mustang, 350Z, or Audi S3, KMAC offers complete arms with on-car adjustability, robust bearings, and high-clearance designs suited for track abuse.
These products are especially valuable for street-driven cars that need to maximize tire life while still looking and performing like a proper sports car.
Application Highlights
KMAC Suspension Solutions cater to a wide range of platforms, including:
European Cars – BMW 3/5 Series, Audi A4/A5/S3/RS3, VW GTI/R, Mercedes C/E-Class
Japanese Sports Cars – Subaru WRX/STI, Nissan 350Z/370Z, Mazda MX-5, Toyota GR86
American Muscle – Ford Mustang, Chevrolet Camaro, Dodge Challenger/Charger
KMAC kits are vehicle-specific, meaning every product is designed to bolt into the stock mounting points with no cutting or welding required. It’s true motorsport-grade tech, adapted for daily use.
Track Handling vs Street Comfort
One of the biggest concerns for enthusiasts is striking a balance between race-day readiness and street-day livability. KMAC engineers its products to meet that demand:
Street-Oriented Kits use high-durometer rubber or hybrid poly/metal bushings to maintain NVH levels.
Track-Focused Kits utilize spherical bearings and fully adjustable top mounts for maximum precision.
This allows you to customize your suspension to your goals—whether that’s a canyon-carving daily driver or a dedicated time attack build.
Real-World Benefits of KMAC
Drivers who switch to KMAC suspension solutions often experience immediate, tangible benefits:
Reduced Understeer: With increased front negative camber and positive caster, turn-in becomes sharper and mid-corner grip improves.
Improved Tire Wear: Adjustable rear camber and toe eliminate the dreaded “inside edge wear” after lowering.
Better Stability at Speed: Positive caster increases self-centering and straight-line tracking, especially at highway and track speeds.
Custom Handling Balance: The ability to set alignment based on tire compound, track layout, or driving style is priceless in competitive settings.
In short, KMAC gives you control—not just of your suspension, but of your entire driving experience.
Easy Installation, Long-Term Reliability
All KMAC products are designed for DIY or professional installation, with comprehensive instructions and vehicle-specific guides. Their top mounts and bushings use high-quality materials that resist corrosion, fatigue, and thermal degradation—making them suitable for long-term, all-weather use.
Plus, KMAC backs its products with strong warranties and proven customer service—a rarity in the performance parts world.
Final Thoughts: Elevate Your Alignment Game
Whether you're racing wheel-to-wheel or carving corners on your morning commute, precision alignment is the unsung hero of performance driving. KMAC Suspension Solutions offers a world-class lineup of camber, caster, and toe kits that unlock your car’s true handling potential—without compromising ride quality or requiring invasive modifications.
Instead of fighting your car's factory settings, let KMAC give you the tools to fine-tune your suspension geometry to suit your goals. The result? Sharper steering, more confident cornering, reduced tire wear, and a driving experience that feels like the car was built just for you.
Small adjustments. Big results. That’s the KMAC difference.
