Whats the gap between your rear wheel and rear arch???

I think parts would have been pre ordered hence incorrect part, as I was given the full price before commiting to the work to be carried out, and was done same day it was dropped in. I will update tommorow .................. hopefully no issue with replacing, it would have been the supplies fault I guess?, the garage would have had my VIN number as they carried out the MOT mmmm, best go bed! :oops:
 
If it helps a 3.0i rear spring for 2003 on sport suspension is part number B33.53.6.761.925 Standard price £72.18 each
 
Rather than measuring the gap, which will be different on different sized wheels if you are measuring from the wheel lip, why not take a measurement from the road surface to the highest point of the underside edge of the wheel arch.
No matter which Z4 model we drive, we can then all determine how high or low ours are then in comparison..
:D

That's not correct as road to arch lip height varies by every model, rim/tyre size and spring combo. I just gave a quick measurement to eliminate the tyre issue knowing the zed was basically the same as mine.

The correct TIS measurements are as follows copied from a previous post:

The suggested BMW factory measure point is as follows:
Attach measure to rim flange at bottom middle and measure to lower edge of wheel arch. By rim size you should get:

Series (Standard)
Front Rear (MM)
16" 589 576
17" 605 592
18" 617 604
19" 630 617
20" 643 630

Sport or ///M suspension
Front Rear
16" 574 560
17" 590 576
18" 602 588
19" 615 601
20" 628 614

All should be +/- 10mm

I checked several different ages and engine sizes and the numbers came out consistent between launch and 2006. I do not know of any reason it changed in later years, but my data does not extend that far.
 
That definitely looks like the wrong springs are installed.

I just measured my car (18" wheels):

Front Rear (mm)
610 608

+/- 1-2mm (it was dark out) they are pretty much bang on to the suggested specs for standard springs.

Just checked mine as above as I am on 19s and I've got to say it's accurate :)
 
Its been confrimed, wrong springs fitted the standard ones were put on it, not the M sport ones. So that the mystery solved , thanks for your help guys , new springs arrive Thursday so watch this space......

:rofl: the worring thing is there standard non m sport ones! back luck if you do not have m sport springs you will have a X4!
 
love your wheels by the way, a spokey style rim with a dish suit the z4 very well !

That is the whole point,
I know they vary by model and I am not saying it is the correct way, what I am saying is that it is an easier way to compare how low eveyones' car is with just one measurement regardless of model or wheel size.
That is the way I determined how much lower mine is after I put my Eibach's on. and that is the quickest way I could determine if mine was lower than an Alpina, a 3.0, a M Roadster etc etc , if they were to measure from road to wheel arch, it doesn't matter if they have different size wheels. you don't have to look at a chart then. :)

Just out of interest when you get a minute can you tell me what that measurement is on your Zed front and rear and am I right in thinking yours is the 2.5 so was not originally fitted with sports suspension?
 
Gookah - I take you point for checking the relative movement of your own car after a modification and sure if you want to know if a 2.5 on 17's with xx tyre is higher or lower than a 3.0 on 19's, etc. , but don't see it has any relevance when people need to know if theirs is set correct and in tolerence, which was op's problem/question.
Those figures are also the ones required to set up the geo.

Dave.... have a look at this linky
 
I had the exact same issue. The ones fitted were for the standard setup and measure 13cm, so I re-ordered the correct part from Joe@Soper.
Did you buy the springs or the garage? Was it an indy or dealers?
