Coilovers

[r33_crusier]

hey guys ive got these section spec RM/A8 coil overs on my 33, they came with the car when i bought them. Appanrently there fully adjustable but was wondering what do:

the little knobs on top of the coil overs do

what do 2 nuts do just under the spring

and what do the nuts do at the botom of the thread

my understanding from looking at the is that the top knob does the damper. how do you adjust it, with an alan key?

the 2 nuts under the spring, do they adjust the stiffness of the spring, so if i lowered that would make it a softer ride but would also lower the car.

dont kno what the bottom one does.

if any1 has any help on this it would be much apreciated.

Thanks Adam

The bottom nut is the lock nut for the base of the shock. Screw this out for more height or in to lower.

The two top nuts are for static sag. Do not adjust your ride height by playing with your sag.

The top knob does adjust the dampening for compression and rebound.

Start with removing the coilovers, with your car on suitable stands.

Set the two top nuts to seat the spring firmly in place, but not tightly to compress the spring. If the spring rate is correct for your car, you should only need to adjust it so the nuts firmly holds the spring in place. Adjusting this any more to increase ride height or reduce statis sag is just a bandaid fix. Make sure you have the right rate.

Next, undo the bottom nut and screw in or out the base of the coilover to raise or lower the ride height. Ensure the other coilover(s) is(are) set to the same adjustment. Put coilover back in car, measure the ride height ... remove and adjust again as necessary. If you need 10mm more, screw the base 10mm more out.

When you've got the correct ride height, take it to a wheel aligners and have the wheels aligned correctly.

Lastly, set the dampening to the middle-most setting. Turn it all the way anti-clockwise, now turn it clockwise and count the turns (or clicks). When at the end and you can go no further (do not force it), count half of the amount of turns/clicks out. Leave it at this setting. I doubt you'll have any need to adjust in the future.

Better still ... take it to a suspension place and get it done properly.
