[Vanne]

Nice upgrade, but holy s**t your metals look super corroded.. anyways to clean that up?

congrats on the coils.

Just MOT'd mine after being in the garage over winter. Went up the road and bang a front spring let go and dropped a bit of coil on the floor. So might invest in a set of these...
Was thinking of moving it on due to lack of use lol...

Hi, my veredict so far is that it is well worth the money, I'm still fiddling with the settings to find the sweet spot and currently the only thing I'm aiming to dial out/attenuate is the feeling of mass transfer front/rear, especially when accelarating hard after braking hard. But it's really much better than the original suspension. I now have so much more stability at speed and grip in fast corners, the steering doesn't feel light and vague at speed like it used to. I get more traction off the lights as well...

In fact I may get a speeding ticket real soon...... :rofl:

I have also noticed - when cruising - that the steering tends to chase road imperfections quicker than it used to, so won't stay dead center as easier as it did but I think that is due to the alignment and not the suspension itself.

In regards to the underside of the car, this is a 118k+ Z4MC that was always used day & night, summer & winter for the last 12 years, I work in a very dirty area of East London that gets very muddy in winter and have to go through some puddles on rainy days too. It is very dirty underneath and that makes it look worse than it is, but I'm looking to get the underside cleaned and protected with Hamber Bilt products this summer! I shall post the results then!

Thanks Beedub! No funny noises at all, no clunks, no squeaking, absolutely as silent as OEM.

I'm more than happy to take anyone considering getting one of these coilovers for a drive. I'm based in Romford/Brentwood.

I have raised the front by 5mm this weekend and it's no longer rubbing.

That's the nice thing about having height adjustable shocks, isn't it!

That’s right! Wish the rears were that straight forward too

OP is this the set-up you went with - looking at following you’re lead with an upgrade to mine as it’s now done 99k and was originally thinking about the Bilstein B12’s kit but then saw these? Cheers

Yes, that's right, looks like the BR kit. Mind that I went for stiffer springs than standard, the kit comes with 6kg fronts, 8kg rear springs.

I went with 8kg/10kg. No regrets, some people got the standards and said they were too soft/bouncy. You don't want to have too soft a spring to then have to compensate by over-damping your shocks , it will be split between a bouncy or a very hard ride.
As a reference the E46 kit comes with 8kg/12kg.

I bought my kit from Corby motorsport, you can get them cheaper than on that ebay ad, call them and they may even give you a discount over the phone.

Thanks for the suggestion here looks like Corby can do the BC kit for £725 delivered which represents a saving of over £500 on the best OEM set-up price I got and just over £900 cheaper than the average price of £1,600. Definately looks like I will be following your lead on the BC's.

hello, do you still have the car?
can you tell us how they behave after about 2 years of use?

thank you very much

The top mounts clunk on BC racing coilovers, stick with OEM. I contacted them and its a common issue on the Z4. Need to get mine swapped out.

Front, rear or both ???
