AST Suspension | High-Performance Dampers & Coilovers

Where to buy AST Suspension in Australia: Chicane Australia lists AST Suspension coilovers, ALS adjustable lowering spring kits, fixed lowering springs and adjustable camber top mounts for a wide spread of cars, from the BMW M2, M3 and M4 and Porsche 911, Boxster and Cayman to the Honda Civic Type R, Subaru WRX and STI, Toyota GR86 and GR Corolla, Mazda MX-5 and Lancer Evolution. Coilover kits are matched to each chassis, and ALS kits keep the factory dampers. AST listings show a lead time of 4 to 6 weeks, so allow for that when planning a build, and Chicane ships Australia-wide from the NSW Central Coast.

AST Suspension is a Dutch manufacturer of performance dampers, coilovers and adjustable lowering spring (ALS) kits, designed and built in-house, with a focus on genuine body control rather than just a lower ride height.

Shop by Product Type

ALS (Adjustable Lowering Springs): height-adjustable spring kits for vehicles with factory electronic dampers. The OE dampers and drive modes keep working, at a lower, more controlled ride height.
5100 Series Coilovers: 1-way adjustable monotube dampers for street and occasional track use.
5200 Series Coilovers: 2-way adjustable (compression and rebound) for drivers who want to fine-tune for road and circuit days.
5300 Series Coilovers: 3-way adjustable, aimed at dedicated motorsport and time attack builds.
Fixed Lowering Springs: progressive-rate springs for a lower stance and reduced body roll on the factory damper. More: Lowering Springs.
Camber top mounts and accessories: adjustable camber top mount sets, a fender clearance kit for the G8X BMW M cars, adjustable sway bar drop links and remote reservoir brackets.

Why AST Suspension

AST builds its own dampers in-house rather than using off-the-shelf cartridges, and uses a low-friction seal design so the damper reacts to small road inputs without the harshness of cheaper twin-tube units. On electronically damped platforms such as later BMW and Porsche models, the ALS kit lowers the car and firms up the spring rate without disabling drive mode settings or the factory dampers.

For cars with passive dampers, the 5100, 5200 and 5300 series give a clear choice based on use: the 5100 for a street car that sees the odd track day, the 5200 for regular track use where separate compression and rebound adjustment helps balance the car, and the 5300 for dedicated circuit and time attack cars. Spring rates are matched to the car, its weight and how it is driven, so send us your chassis code before ordering rather than working from a generic rate chart.

Choosing the Right Kit

AST kits are application-specific, so confirm your exact chassis code and factory suspension type (standard, adaptive or electronic damping) before ordering. On BMW and Porsche models with factory adaptive dampers, an ALS kit is usually the correct choice rather than a full coilover, as replacing the OE damper on these cars can trigger fault codes or remove functionality.

Installation & What You'll Need

Installation by a professional is recommended. A wheel alignment is required straight after fitment, as ride height changes affect camber and toe. On some Subaru and Audi AWD platforms, front top mounts and rear camber arms may need attention to bring geometry back into spec.

FAQ

Where can I buy AST Suspension coilovers in Australia?

Chicane Australia offers AST Suspension coilovers, ALS kits and lowering springs and ships Australia-wide from the NSW Central Coast. Shop by vehicle above, search by AST part number, or email our team your chassis code and how you use the car so we can help match the right kit.

What are AST ALS (Adjustable Lowering Springs)?

ALS kits are height-adjustable spring systems that replace the factory springs while keeping the original dampers. They suit cars with factory electronic suspension, allowing ride height adjustment without dash errors or losing drive modes.

Will an AST coilover work with my car's factory electronic dampers?

Generally no. A full coilover replaces the damper, so on cars with factory electronic damping an ALS kit is the correct option. Send us your chassis code if you're unsure what your car has.

Are the 5100 and 5200 series suitable for street use?

Yes. Both are designed for street-driven cars as well as track use, with a low-friction design that gives a more compliant ride than many budget coilovers.

Do I need an alignment after fitting AST coilovers or ALS springs?

Yes. Any ride height change affects camber and toe, so an alignment straight after installation is essential for tyre wear and handling.
