Spring is in the air! Help please..

[Dazza4]

Spring is indeed in the air, as I think my front springs have given up and are now not holding up the front of the car.

I have not put the car on a ramp, not driving it any further. Looking to get into Indy via a recovery flatbed.

My question is what should I replace the springs with? Car is 35is and on 70k+ miles. Not looking for performance/track set up, or to massively lower the car

1. OEM
2. Eibach
3. Bilstein B8 or B6

And I guess it would make sense to replace the rears too?

I don’t know much about this stuff, but obviously want to sort before the summer ( ), so any input is very welcome.

Cheers

Bilstein B8 with appropriate Supplex springs…simples..

Thanks B21, I guess the adaptive would need coding out then if I replaced the shocks? And which Supplex springs do you recommend? And I like simple

Yes the adaptive ecu needs removing then the VO needs recoding to avoid errors..

Look on Autodoc supplex springs for 35i MSport to get the correct version.

So, (1) you don't know what's happened, but (2) the car's undriveable.

What's the car telling you has happened?

Depends on budget, lowering springs/new shocks will lower the car to a set height and dampening and you're stuck with it, I went with BC Coilovers, I can set the height and adjust the dampening to get the car exactly how I want it. I personally found Eibach springs too soft and H&R too hard, got my BC's set up so the car sits at the height I want without compromising ride quality

Nope, it was fine the previous weekend. Went to take it out on Saturday and there was an unhealthy noise from underneath. I can drive the car, but prefer not to, without understanding the root cause. Visually, the front end has dropped considerably, tyres could easily rub.

The car is not showing any errors….

Cheers Dave, car looks great, especially with the black alloys.

My experience and nothing more is that 35iS variable suspension failure included an error display and leaking damper(s), but not "an unhealthy noise" or a "front end [that] has dropped considerably".

I've replaced 6 corners and your symptoms don't sound like mine at all.

Do you own the world's only hexagonal E89?

[Busterboo]

I'm pleased that, at 104,000 miles, it's not octagonal. Yet.

What's RBM, please?

Have you solved this problem, Dazza4? If so, what was it?
