This kit isn't one of our regularly stocked lines, so it's built and air-freighted in specially for your order. That's the only difference — it takes a little longer to reach you than something off the shelf.
Everything else is exactly as you'd expect: a genuine BC Racing kit, full warranty, and our team confirming the fitment for your car before it ships. Because it's ordered in to your spec it can't be returned for change of mind, so it's worth double-checking the details before you order.
Due to this item being an air freighted coilover kit for your specific order, It is crucial for customers to carefully review their orders before finalising them. By placing an order with us, you acknowledge and accept responsibility for the accuracy and correctness of the items selected. You also agree that this kit cannot be returned under any circumstance due to the above.

Steel-braided lines feed external reservoirs that add oil capacity, store extra fluid for cooling under prolonged track use, and house the secondary damping piston.

About the HM series
The RM and ER combined for your car: an inverted mono-tube damper with 2-way independent adjustment, plus external reservoirs that keep damping cool and consistent through prolonged track use.
This kit is configured as HM-OFF — an inverted front damper with a pillowball top mount and external reservoir, giving a direct steering connection, less unsprung weight and more fluid to keep damping consistent. The rear also runs an external reservoir, and is inverted on the vehicles that allow it. It ships assembled and ready to bolt on out of the box — allow time at fitting to choose a mounting position for the reservoirs.
Common questions
Will this kit fit my vehicle?
Yes — this kit fits all body styles.
If you have a non-standard chassis or factory suspension upgrade, contact us before ordering and we’ll confirm fitment.
Can I adjust ride height after installation?
Yes. All BC Racing coilovers use full-thread body construction for continuous height adjustment without affecting damper travel.
We recommend a wheel alignment after any significant ride-height change.
How do I adjust the damping?
Damping is adjusted via the top-mounted dial — turn clockwise for firmer, counter-clockwise for softer. Always start with all four corners at the same setting and adjust in equal increments.
