Description

BC Racing ER coilover kit Toyota Supra MK4 JZA80 (93-02) 16/12 kg/mm

The BC Racing ER coilover kit Supra JZA80 16/12 (part number C-15-ER) is a coilover kit adjustable in height and damping, also simply called a coilover, for the Toyota Supra MK4 (JZA80), model years 1993 to 2002, and according to BC Racing UK also the Toyota Soarer (JZZ30). The spring rate is 16 kg/mm front and 12 kg/mm rear.

This is the stiffer version of the 2-way adjustable ER kit that BC Racing makes for the Supra MK4. Under the same part number there is also a version with 14/10 kg/mm; this one comes with 16/12 kg/mm and is intended for a JZA80 that is mainly driven on track or in competition.

The ER dampers are monotube with a double piston and an external reservoir. You adjust compression and rebound in 30 clicks each, independently of each other, and the digressive damping with fully synthetic oil keeps the body under control during slow movements.

Route the reservoir lines so that they do not chafe or kink anywhere, and have the wheel alignment set after adjusting the kit. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If the kit is temporarily out of stock at BC Racing, you can still order and we will tell you the expected delivery date.

The BC Racing C-15-ER in the version with 16 kg/mm front and 12 kg/mm rear is the stiffest ER spring choice for the Toyota Supra JZA80, with 2-way adjustment and an external reservoir.

Why choose this ER coilover kit Supra JZA80 16/12?

If your Supra MK4 mainly goes on track, a stiffer spring choice may suit your setup better. This version combines 16/12 kg/mm with 2-way adjustable ER dampers, so you tune compression and rebound for the circuit independently of each other. If you are unsure between 14/10 and 16/12, feel free to ask us for advice.
