I have a set of zeal function coilovers for sale.
The fronts are 6 way damper adjustable and height adjustable monotube
The rears are height adjustable
It comes with a spare pair of rear 6 way damper adjustable and height adjustable monotube, but they have a small nick in the shaft. Might be fixable but might not.
They come with both the eyelet type and the fork type rear bottom mounts so they can fit either R33 or R34
Spring rates are around 9kg, so excellent for circuit work
$800 for the lot
