It's been a few years since I've adjusted the coilovers & can't quite remember how it's done. Could someone refresh my memory please? I don't wana mess it up. Thanks.

Assuming you just want to adjust the ride height and not the preload(?), you just unlock the lower collar onto the bottom bracket and use your keys to rotate the shock assembly in the correct direction. This will screw the shock absorber into or out of the bottom bracket and lower, or raise the ride height.

If you’re not doing the preload there is no need to touch the double locking collars at the base of the springs, you just use them with your key to turn the assembly round once the lower collar is loose. If you’re lowering the car, you will be screwing that threaded portion further into the bottom bracket, if this is the case, make sure you clean up the threads going into it and lubricate them so you don’t damage the coating. The easiest way to do the adjustment is to wind the locking collar up, the amount you want to go down and turn the shock until it touches the collar, then lock it back up again.

 

It’s always a good idea to give these some TLC as a maintenance item to keep them in good condition so give the whole lot a good clean up and reprotect whilst you’re there.

Thanks Joel. Yeh it's just ride height, rears up a touch. So I'll release the bottom locking collar & then twist the shock around? Where do I put the key to move the shock? On the preload?

Use the smaller of the 2 collars under the spring (this will prevent that collar from loosening) to rotate it with weight off the wheels. Make sure you can still see the threaded portion of the shock through the witness hole (which is about an inch down the bottom bracket from the locking collar) as this marks the maximum safe height adjustment. On mine, I found that I couldn’t go high enough with the witness hole so I had to decrease the preload in order to gain height!

Thanks Joel, I'll give it a go this week. Don't wana mess with the pre load if I can help it.

The preload amount is marked on the spring though not sure if you will still see it if they are old.

 

Defo don't want to mess with that, I did on my Skyline and it was an interesting experience driving it till I sorted it lol.

How do they mark it?

It’s printed on the spring within the text. The number will be longer but part of it will be something like 220. I can’t remember exactly but 220 rings a bell. The preload is simply a measurement in mm from the top of the spring to the spring platform. So basically how compressed the spring is.

 

In a normal setup these would be the same each side but if you were ever to get the car corner weighted, they would set each corner preload individually depending on the weight at that corner to balance the response of all 4.

Thanks Joel. Might as well check everything while the wheels are off.

You were right Joel. 220mm. The passenger side rear was 10mm different so hopefully now I've changed it it will be a better ride. Don't know why it was different, so called Zed specialist & his apes most probably.

Happy days mate :)

Thanks for the help mate.
