Ha, how hard can it be!

If only BMW made half decent springs in the first place

Sopers quoted me £235.81 for OEM, collection only due to weight.

Isn't that a load more money for what is generally considered a sub standard part? Genuine question.

Suplex are considered decent however when I fitted them to my car the ride height increased.

I wouldn’t fit them again nor recommend them to anyone. Albeit I also understand that some forum members have fitted them to their Z4s and had no issues.

In disappointment I’ve decided to do a complete suspension overhaul and will be installing KW V2s later this year.

Interesting ta - that's the first negative review I've seen. Assuming I ever get my hands on a set I'll keep an eye on the ride height.

I bought 2 * 06248 and 2 * 06231 Suplex springs from autodoc for £160, shipping included. Got them after a week or so.
I fitted the rear springs along with the B4s I also bought and will shortly post my photo DIY, even though it's a dead easy job to do.
My main problem is -just like my most car DIYs- that I'm always missing the wrench/socket/tool etc that's essential..

I will take the front B4s tomorrow at a garage so they can place the suspension inside the springs as I can't justify buying a spring compressor (or should I??) and then install them.
Preciously my zed had crashy ap coilovers and was unbearable. I could barely fit one finger between the wheel arch and the tire and now I can fit 2; don't take that seriously though, cause fronts must be replaced as well for a safe comparison.

I've been looking at this in case mine go in the future, but here's what I find hard to justify...

I COULD just replace the rears for £120 or whatever it is these days for 2 springs, but a full set of Eibach springs is £140...

I think the Eibachs are slightly lower than standard m-tech though on the 3.0 - wouldn't want the Zed any lower than it is currently, it's already a pain in the ass over speedbumps etc.

The rear 06231's are really difficult to find at a reasonable price. Not so long ago they were around £35 each. Anywhere in stock they seem to be asking for £65 each

Replaced with suplex too about a year ago, no issues. I think they were about £70 or £80 for the rear pair

Well, this just gets better and better.

Springs should have been delivered today, that's being generous with the quoted '2 to 3 days' delivery time. Phone them up - no record of my order. Asked for my Ebay username a few times (I placed order on their website) to be told that they don't receive details of these web orders (yet - seems to be new).......!!! Chap then ordered from his supplier, should now be with me on Thursday. At least I 100% heard him order 06231's.... Sigh.

I also ordered a stand for my hard top from Ebay. Again, delivery date came and went so I sent them an email - their response was (they are based in Germany) that DPD could not find my address on their database, so refused to pick up the parcel for delivery.

This house is about 30 years old

Ha, that's nothing, my house was built in 1830, we have lived here since 1999 (last century

) and they still claim to not be able to find it!

Have you gone for one designed for the z4 or is it a universal type?

Timmyboybunter · Post by **Timmyboybunter** » Mon Mar 18, 2019 6:43 pm

Exactly the same as my experience - this is a company called 'ECD' but they seem to go by several names, all with huge feedback scores.

This was just a universal type but as the Zed is quite small should be fine. I've ordered what looks to be a very similar item from 'UK Custom Covers', comes with strap but no cover (not bothered, I imagine the ECD cover would be worthless) for £80 rather than £60 for the ECD item.

Note the replacement I've bought was from Amazon, it is £10 more on Ebay and the UK custom cover website.
