Seriously though, I have used the extra ride height on a couple of occasions, whereas in my 320 would not managed it.

But the sdrive is hardly a lowrider! It has fairly considerable ground clearance imo!

Dopper99 - Glad to hear that the ride is still really smooth. It would be a shame to lose that.

I had forgotten about your adaptive issue. There is undoubtedly a fault if the difference isn't obvious on anything other than a smooth surface. Once you have tried another with it, I don't think you will let the dealers get away with fobbing you off again.

The only issue I have before getting these fitted are, what happens if a problem occurs with something like the brakes for example. BMW refuse to repair under warranty due to springs but ACS refuse the claim also because they believe their springs are in no way responsible for the problem with the brakes.

What happens then? Who takes the hit? Got a funny feeling there might be a grey area in between the ACS warranty and the BMW warranty...

Yes Pete, when I put it into Sport the steering stiffens a tad, but thats about it (if I have chassis only ticked). When drivetrain and chassis are ticked then the gearbox programme changes in Sport mode like it should. When I put it into Sport+ the throttle is more lively and gearbox also changes programme accordingly.

I'm still thinking about this mod too. Just means my car will need to stay on the road and not on my drive...
Is it me or is the drop a lot less than expected?

[NISFAN]

Sounds like a good result @dopper99

Will this springs work on Adaptive Suspension.?

There is no way that BMW would not do warranty work on one part of the car because you modified another part.

Despite urban myth and conjecture that manufacturers will use any loophole to wriggle out of work, it's just not true. It's not in their interests and definitely not in the dealers interests either.

It was 2cm all round for me, so much what I expected. Visually, I think it looks perfect at the rear, but the front looks like it could go lower still to improve looks.

If anyone is doing this wanting or expecting a 'lowered' look then I think they would be disappointed. To me, it looks just right and is icing on the cake that is the handling improvement!

Yes. Works very well. Comfort mode is fine for most driving. I think the difference when you move to sport is better, and more suited to when you really want to get the foot down!

It's also against EU law to decline a claim due to an unrelated part being fitted.

Yes agreed, I think it looks fine and doesn’t draw enough attention to make it look unnaturally low – it just looks normal.
The back is a nice height but the front is a little higher compared to the E90 standard M Sport (see pics in first post), but I guess there is a technical reason why its like this, which is fair enough. All in all, I’m very pleased.

Funnily enough when we parked my car next to the M3, we both commented on similarity on wheel arch clearance at both ends - if anything M3 was riding a weeny bit higher (still looks gorgeous though ).

Sorry, just being hypothetical here. But where is the evidence to say the unrelated part wasn't partially responsible, in certain cases it might be impossible to determine the cause of the problem. Maybe a problem with the brakes could occur because the firmer springs have caused something to rattle loose. BMW say it's due to springs, ACS say it's not. I could be totally going over the top but it's just my luck that something like this would happen to me!

One thing these springs do not make the ride any firmer IMO.
What they do is provide better control. Better control for the ride and control for the handling. Because of this, I’d say they should be kinder to the components if anything.

With these springs you’ll realise it is possible to have good handling without rock hard suspension!

Yes, it wont turn it into an M3, but its a big improvement on the standard 335d springs.

I'm fighting a pointless argument with myself because I'm almost certain getting them fitted! Just being a bit cautious about the whole thing. Not heard a negative review yet.

I wouldn’t worry too much about the warranty side, its taken care of and enough people have been confident to have these springs fitted and hence satisfied it will all of taken care of if a problem occurs.

With regards the ride (ie something you have to live with every time you take the car out!), absolutely no worries there. I took the missus and kids out in it the after they were fitted and didn’t get any negative comments, the missus said “seems alright to me” which for a non-car enthusiast is good enough for me . The kids MUCH preferred my car against the X1 M Sport I’d had as the loan car as it was very bumpy for them.

I think the warranty and ride are probably the only things that may be worrying people and IMO there is no issue here.

[dopper99]

With regards the cost …….. talking to my mate the other day who has a Z4M. He had to pay for a service that included setting/adjusting valves and god knows what and that came to £800!!! Puts things in perspective when you can get these springs fitted for less than the price of a service for a Z4M!
