Pulled the trigger on a set of BC Coilovers
So Today I have installed... the fronts only
Front coilovers, ARB bushes and end links. Replaced all bolts too with new items that BMW kindly provided in exchange of £54
Only started at 12 and it took me six hours. Mind it was the first time I did this sort of job.
Well, having only done half a job gave me the opportunity to compare the front coilovers vs the original rear suspension. Adjusted the damper to 14 out of 30 settings to start with (0 being soft, 30 being hard).
The car rode very well in the front, not bumpy, not crashy. Reacted well to road imperfections, pot holes and speed humps. Better than the rear suspension (which is tired to be fair) and better than I ever thought it would. Did hear two very shy clunks going over two deep potholes. (Intentionally ran ober them) Also noticed what people refer to as NVH (noise, vibration and harshness) due to the solid mounts, but nothing really invasive or disturbing! Some of it might even go away once I get the geometry right and an alignment done.
On the way home, near my local town (Brentwood) I pulled over to turn the knobs to full soft before entering the high street (which is partially cobbled). I was positively surprised with:
1. How the feedback through the steering wheel was so much nicer and smooth than before.
2. How soft the suspension was! It absorbed those cobblestones so well it reminded me of my 320d SE Don’t think I will ever set it to zero again, but nice to know the adjustment knobs really do their job ahah
Did not try full hard, think it will be stupidly stiff for the road anyway
So there you go, this is my non-conclusive front-suspension-only First Impression.
It’s promising, now I need to find time to fit the rears...

I found that only about 5 clicks off soft worked on my Solstice (10 clicks on the rear).

look awesome - cant wait to hear feedback
i have run these on last 2 cars owned including my e89 and i loved them. easy to dial to firm for track and easy to put back. just need a jack for rear. 1 small bit of feedback if u dont mind ... ask installer to make sure H <--> S sign visible once installed (rear)

Beedub, do you know what is the approximate turn around time? I’m considering having mine serviced before I ship my car to Aus, simply because it’s going to be ball ache from the other side of the world.

You are closer to the factory (Taiwan) and it would probably be quicker and easier to deal direct from Oz. I bought direct from Taiwan to Canada.BMWZ4MC wrote: ↑Wed Jan 31, 2018 11:55 pm I’m considering having mine serviced before I ship my car to Aus, simply because it’s going to be ball ache from the other side of the world.

Cheers guys
Thought you’d not been around much Beedub. Good luck with the new business.

Very keen to hear the verdict too on these - I'm coming from B12s and looking at something fairly daily friendly that will work on tracks occasionally. Aware these are more of a budget coilover but as previously the various good reviews from m3/5 owners have to mean something!
Just to add to this having thought at some length this evening - could you set them up full hard and let us know how firm it is I'd like to know there's enough range of adjustment to manage some track work as well as being sensible for road use if poss!!

Also - in the last pic above, you have the coilovers, and adjustable droplinks and what looks to be adjustable rear camber arms - do these come with the BC Coilovers, or did you purchase from Powerflex or similar? Keen to know as I'd like that additional adjustability too, and it's deffos another big plus for the BC Kit if they come with!Gustavo7 wrote: ↑Tue Jan 16, 2018 8:33 pmWell, tomorrow is the big day.

The rear camber arms (and the adjustable front end links) were a separate purchase to the coilovers. The rear camber arms are the Powerflex ones.
I have unfortunately been unable to drive and work on the car in the last couple of weeks as I have been recovering from an emergency surgery. There were 75% of chances it would require further intervention. - It does, so I’m now sorting paperwork for a second operation which shall take place next week.
I personally don’t think I will be driving the Z4 before March. And that’s probably the best case.
So bear with me, I will provide all the feedback in the world once I’m fit to drive

Hi Gustavo,
Best wishes for the recovery and second operation.
I know how this feels, I was ill pretty much the day I got my zed (actually must have been several months before..) and unable to drive it for several months.
I would love to have a ride in it when all is good. I'm looking at changing my suspension at some stage.
Cheers, Alan.

Sorry to hear that chap - wishing you the very best for a speedy recovery!
If it's any consolation I nearly lost my leg below the knee in a climbing accident - 6 ops and 5 months on crutches later I was thankfully able to still drive - feels like forever but its the best feeling in the world when you do finally make it back in the car!

somewhat tempted by some BC coilovers... I do do trackdays so would likely go for the harder springs, but budget wont stretch much past these. Plus really need something with adjustable front camber, want to be running -3 deg at the front or so.
will be keen to hear how you get on with these when they're all on and set up, wishing you a speedy recovery from surgery!

Update:
The Zed is off to Scotts Performance Cars in Dartford to get the rear suspension, powerflex bushes, RTABS and adjustable camber arms fitted together with a 4 wheel alignment.
Any advice on suspension geometry for a road car? I’m inclined to start with the z4m original geometry and play it from there...

Go for the E46 M3 CSL alignment - makes for a LOVLEY drive
