I used this guide this weekend - thanks so much PawnSacrifice (if you're still here?!)!

One bit of really useful info would be the socket sizes required which would have saved me a bike ride to Halfords half way through (none of my 3 sets had an 18MM socket!).

Also, I've only done the rear so far as I hit issues with the front end (insufficient spring compressors).

For the front, can anyone let me know if it's ok to atleast de-torque the bolt in the top of the front strut whilst it's all bolted up? It's going to be a bugger to steady/grip the strut on my own whilst giving it enough oomph to get it undone when off the car....
Hi Darkangelv2 do not detorque the bolt in the top of the front strut at anytime unless the spring compressors are on the spring as it will release all of the energy stored in the spring. I had to use two sets of spring compressors to to sufficiently compress the spring when I changed mine.
IIRC Once compressed you should see that the top of the thread that you remove the bolt from has a allen key slot. What i did was put a socket onto the nut then pass the allen key through the socket and then use a spanner to twist the nut while holding the allen key.

You legend, thanks very much. I've bought a much better set of spring compressors now (specifically call themselves MacPherson Strut type) which look like they'll be safe and secure.

I had read about an allen key being used to hold the strut but struggled to see how it will be done when I had it in front of me. My sockets don't have a way of using a wrench on them so not sure how I will manage that. In case, I've bought a clamp that secures to the strut without damaging it and you can put a spanner on that.

Either way, I won't touch the bolt until I'm compressed. :thumbsup:

I had a socket like the one in the link below which I think was for a spark plug. It has a flat on it that I put the spanner on. I'm not sure what size you need.

Great guide will hopefully be following it in a couple of weeks!

My new z is just slightly too low and scrapes going into my garage and on speed ramps. Need to find out what springs are actually on it first.
Although it's been up on a ramp and nothings being damaged...

Yeah, I was slightly amazed the guide's not sat in the 'How-To' section.

As I say - 18MM & 16MM sockets required! And definitely a breaker bar of some sort (atleast 450MM).

Also, Check and check again that you have your springs the right way round :thumbsup:

as you can see from this, i WILL be doing this at the weekend, i collected 4 new rubber bump stops for the rear yesterday from dealers to fit at weekend as mine currently has NONE and i think 1 of the springs is upside down...

I used the extra thick (14MM) rear pads as I wanted to avoid the rear end sagging at all (sometimes they don't sit 'level' after lowering).

You will know they are the right way up because the pad's 'nipple' will slot nicely into the correct end and vaguely hold rather than having to be forced in if you do it the wrong way round.

Thanks for this.

I've bought one of these already through as I reckon it'll be v useful for other stuff too.
