how strong is suspension on Z4?

Chances are that in the countries where they are on for a significant amount of time/all the time, the ambient temp is very low, so no huge issue.

Of course, leaving them on in the middle of Death Valley in the middle of the day is a bad idea I would imagine, but why would you ;)

lol, we have about 2 weeks of sunshine, 10 months of rain and month and a half snow blizzards. No worries about desert scenarios. :headbang:
 
The RHS rear spring broke on my 2004 2.5. It was caused by a corrosion induced crack emanating from a pinprick in the paint. I guess it was caused by a stonechip. The springs are set quite low in the car and maybe stones start corrosion off and that leads to failure. Thicker or stronger paint or deflectors would sort it. The Telegraph is wrong about the cause and for the record the end of the spring is tapered off.
 
If you look at a proper jap spring you'll see the difference between a machined taper and a straight cut (which is what the beemer spring is....it relies, as someone has said above, on the fact that the last coil is effectively flat, but that still puts a different stress into the spring than a machined taper does).

You can do the research yourself; minibloc springs are significantly less reliable than the equivalent barrel spring.

Oh and I'll be sure and tell the Telegraph motoring guy that he doesn't know what he's talking about :roll:
 
I'm not sure how the stresses are much different, but hey ho.

I've seen broken springs on all cars at some stage or another.

I think in this case it is just a bad design or under-engineered more than anything. I bet you could get a copy made up by a spring manufacturer and them never snap... after all, loads have similar after-market ones and no snapping, and they are essentially the same seating style.

Just BMW made a crap rear spring for the Z4 :)

RFT probably don't help either (did anyone see Watchdog and 19" RFT from BMW?! Lots of alloy wheel cracks/failures apparently)

I was told the other day by one of the bmw techs that my bushings were ever so slightly getting worn on my 03 3.0l with 58000 miles on them. However what he didn't know was that I had at that point been to numerous track events and drove the card hard, plus in Vegas 99.9% of parking lots have speed bumps in them. The condo I lived in had about 11-15 speed bumps that weren't pleasant at any speed to cross, and I had to go over those at least twice if not 3 times a day.

My lights are real bad atm due to the sun/heat in Vegas. I need to go get another headlight restoration kit and buff em out again.

When you see what can be done though, with wet and dry sanding paper and a rotary polisher on headlights, you do kinda start to think if you just invest in one and a few good pads you have it for life... and can do these kinda jobs easily :) (I bet the restoration kits will start to add up over time for example)

They also do kits for windscreens which is nice if yours is pitted (that said it's probably easier to get a new screen than start polishing away at one :) )

:rofl: :rofl: Aye it is.

If it makes you feel any better I'm loving the weather here! Well minus the cold part, but I'm adapting, been going topless in 55+ degree F. weather.
