Rear Coil Springs

Passenger side coil spring is snapped inside the cup. I read this is a common problem on the Z4. Indy spotted it when he did my rear disk and pads - he is a top guy and very reputable. Said it should be done as soon as possible so he has got me booked in next week. He said drivers side was ok and it is up to me to decide if to do them both at the same time. Did not have to be but most people get them both done. He quoted me £220 inc VAT to supply and fit both. Not a big job - about 70- 90 mins to do both.

I thought might as well get both done - do you think that's wise?
 
yeah i guess thats about right, fairly straightforward, hardest part is taking the wheels off to be honest.
he should take only a hour if that for both, :thumbsup:
 
Watch this ...piece of cake, I've just bought a rear from EuroCar Parts..£48 and it's a Sachs, usually good stuff.

Thanks for your thoughts - deffo getting both done then.
I don't think 220 all in is that bad.

So since I have had the car - four weeks - I have had done:
> Oil service - didn't need it but did it anyway.
> Rear pads and disks. Started to hear them grate :o
> Rear coil springs

Hopefully after MoT in April she should be good to go for a year or so.
 
Cleaning the rear wheels yesterday and guess what I discovered ? yep, another broken spring...picked one up at EuroCar Parts £48ish.

When I checked the uncompressed height off the car of the ecp Sachs (non-sport) rear spring next to a complete oem non-sports spring the Sachs was slightly shorter, but thicker on the ends and lacked the thin pig-tails that seem to snap off. I replaced both my rears and was worried the fractionally shorter springs would affect ride height, but after careful measurement it sits as standard, I'm assuming this must mean the Sachs are slightly shorter but stiffer so initial compression at rest is less. I would say this translates on the road to a very slightly 'tighter' feel which I think suits my car having moved to slightly softer walls on the non-RFT tyres.

I don't think changing one spring is recommended, particularly not with different makes and definitely not if you are mixing oem and Sachs as they are slightly different heights and rates, so a pair is the way forward :thumbsup:

At £220 you are paying over £100 labour for a 30 minute job. Suplex and other brands can be sourced for under £100 a pair. I did the job alone on my drive and it took under an hour. With the benefit of a ramp/lift and another pair of hands for a minute or two here and there this is a 10mins per side job.
 
I have a set for £30, 2 rears have done 6k and the 2 front ???? off my car at 91K. "03. 3.0
