Description
Toyota AE86 Corolla with spindle (83-87) BC Racing ZX coilover kit 6/4.5 kg/mm
The BC Racing ZX coilover kit AE86 spindle (part number C-14-ZX) is a coilover kit adjustable in height and damping, also simply called a coilover, for the Toyota Corolla AE86 with rear-wheel drive, model years 1983 to 1987, in the version with spindle (W/ SPINDLE). The spring rate is 6 kg/mm front and 4.5 kg/mm rear.
The ZX series combines the construction of the DS with the external reservoir of the ER. The result is a 3-way adjustable damper for competitive track use, long sessions and demanding drifting: 20 clicks for low-speed compression, 12 clicks for high-speed compression and 30 clicks for rebound.
This ZX is the version with spindle (W/ SPINDLE). BC Racing also has a version without spindle (W/O SPINDLE) for the AE86; choose the one that matches your car and ask us if you are not sure.

Why choose this ZX coilover kit AE86 spindle?
When drifting and in long track sessions, you want the AE86 to behave the same every lap and to be able to adjust the damping very precisely. The ZX gives you three separate settings per damper for that. That way you tune fast movements, such as over kerbs, separately from the slower movements of the body.
