replacing rear springs

[Coyote]

Changed my rears today, took no time at all.

I found it easier to use a scissor jack to force the arm down rather than a bar, as I was on my own I couldn't get adequate movement on the bar and get my hand into the spring at the same time.

My technique today for pushing the arm down.
My weight kneeling on was not enough so added a bit more to the plank

hi i got them from main dealer seems about the only place unless you want to lower the car then most go the eibach route, press the dealer for a 10% discount i got mine for £152 good luck

They cost me £198 today Is that 3 years of inflation?

And 18mm, where on earth did that size come from? lucky I had an oldone kicking around.

I have just changed both my rear springs on my 2007 2.0i (With M-tech suspension) as the OSR spring was broken.

Originally i contacted SUPLEX UK on forum member 'Lillywhite' advice and to be fair they where very helpful and quoted me £125 for a pair of (Part no. 06229),
but after a last min search on ebay i found this seller selling Surplex spings for a 2.0lt, but the part number was not the same as SUPLEX gave me, so i asked if they had any with the part number 06229, and BINGO!:

£65.31 the pair bargin!!
The are advertised as for a 2.2lt but i too the gamble as the part number matched that which 'Lillywhite' & Surplex had told me.

I have seen people on here fit the wrong springs on Z4's with M-tech suspension and there factory lowered cars end up 3" taller than normal at the back, but luckily these are the right ones

Its Not impossible to fit them on your own and its not a hard job, but it would have been alot quicker and easier if i had someone with me to push down the suspension arm. I used 2 iron bars and swore a lot but got the job done.
Just to note, when you jack the car up at the back for any reason, once its then back on the ground itll sit a inch or so up, even if u sit in the boot? I dont know why this is but i noticed it when i changed my alloys last year so half expected it (altho at first i was a little worried id had actually got the wrong sized springs "Phew!!"
:driving:

Good spot, ESP. I can confirm, that according to Suplex's catalogue, spring ref 06229 fits both the 2.0i and 2.2i models with M sport suspension. :wink:

Can you describe where you put the scissor jack or is it just obvious? - I think I prefer this method to the bar method.

Does any body know if the Suplex part no. 06229 fits a 3.0l car? I don't want to go any lower and I would prefer to avoid BMW.

Easiest thing to do with stuck nuts like this is to pop round to your local tyre shop and ask them to gun it loose and nip it up. That way it will be easier for you to get the nut off. I used to do that before I got my electric hammer drill, most useful tool ever!
