Know your setup.
Illustrated guides to choosing coilovers, understanding the parts and looking after the fitted kit.
Choosing your kit
Compare the options against your car and how you use it.
Cars with electronic dampers
Check the original equipment before ordering a replacement kit.
BC Racing BR or DS?
Compare the damper specification, then check the kit for your car.
Coilovers or lowering springs?
Choose around the height adjustment and damper changes your car actually needs.
Choosing coilovers for road and track
Compare the kit against your roads, tyres and setup plans before counting adjusters.
Understand the hardware
See what the components and controls do.
Damping adjustment explained
What combined, two-way and three-way controls change.
Spring rates and top mounts
Read the front/rear figures and check which mounts come with your kit.
What spring rate tells you
Compare force and movement, read the units and choose a spring with the damper in mind.
Monotube and twin-tube dampers
Understand the internal layout without treating tube count as a ride-quality score.
When the rear spring sits beside the damper
Why a coilover kit can retain a separate rear spring and how to identify the adjuster.
Fitting and setup
Plan the height, clearances and finished geometry.
Ride height and spring preload
Understand the two adjustments before choosing a lowering range.
Alignment after changing ride height
Set the intended height, check the geometry and keep a useful record of the result.
Your first setup after fitting coilovers
Start from the supplied instructions and make changes you can trace.
Wheel and tyre clearance with coilovers
A wheel diameter alone cannot confirm clearance to the spring, damper or body.
Parts and aftercare
Identify a component and keep the right records.
