Great work
@TriggerFish , so many questions. This is a job I would like to do one day. Is there a thread on here, where do you start, what tools required etc?
Thanks! I'm hoping it'll be worth the effort. From my research (based on the E46, as there's so much more information!), I'm going with:
- stock rear rta bushes with load limiters
- poly rear subframe
- all 4 hub joints as ball joints (as per the m3)
- everything else standard
This video is basically all you'll need:
I think on the z4 it is tighter with the diff, so I'll probably:
- fit the suspension arms to the subframe
- fit the subframe to the car
- set the suspension to height and torque up
- remove from car
- fit diff
- refit subframe and dif to car
So far no special tools. Just a socket and spanner set and an E12 torx bit. Impact gun is useful for fighting the tough bolts.
I bought this tool. I've only done the upper arms with it so far, but with an impact driver, it made it a walk in the park (once I'd worked out how to use it!)
I'm just doing it on axle stands at home. I just jacked it up and started unbolting stuff, starting with the exhaust and working upwards. Honestly, the hardest part so far has been getting the prop shaft out of the diff as it was a bit stuck. It's all logical and pretty easy if you're confident with mechanical work. Just time consuming and awkward working on your back a lot.
