Hi Dom

IMO and many others on here THE springs to fit are the Eibachs, nothing else will do.

Ideally you should be fitting a Bilstein B12 kit as the lowered springs require a shorter shock, which are included in the kit.

If required we do stock these, and I am sure we can beat any other price you find for these.

Regards
Martin

True on the Eibach but depending on the application a Bilstein B4 OE damper will work very well as Pro and Sportline are designed also to work with OE .

Normaly the sportier OE damper is selected in the suspension range .

As said by Martin , uprated springs equals uprated shocks , standard setup struggled when brand new so either go OE new springs and shocks or be wise and go the Eibach /B8 route

Plus I don't think your warranty is valid if you use B4's with lowering springs.

Not at all , like I said they're designed to work with OE but best to pick the right OE , so in the VAG world a Sport suspension or S-line OE B4 damper would be selected over SE / Standard .

As Eibach are very comfortable and fast road orientated
( they're not all progressive rate , some are linear ) , but depending on the application H&R can be very track focused so the B8 damper is a no brainer to provide the extra damping for the more extreme spring rate .

No, no, no. :wall:

VAG is irrelevant. On the 9-5, B4s are basically OE non-Aero spec. Completely useless with the Eibachs (they only do one type for the 9-5 and yes it's progressive). The OP might want to listen to those of us who have actually tried these damper and spring combos on the 9-5 and are speaking from experience.....from my own perspective:

Eibach and FSDs - great ride quality, but where handling is concerned? Nope, the dampers can't control the springs - they're an upgrade for standard length springs - much like B4s (several guys have tried B4s with Eibachs to save a couple of hundred quid, and most regretted it).
Static rate Abbott or Progressive rate H&R & B6 - OK - stiff, bit bobbly on the ride. The shorter B8s would be better. Good road/track set up
Eibach & B8 (aka B12) - best road set up you can have - dampers are the right length and have the right level of control for the springs.

Yes , yes , yes , this is what I'm trying to tell you , you select the sportier OE B4 damper so that's aero ? in the Saab world .

What kit part # Eibach is it for the 9-5 ?

For example if with Eibach's Pro kit - 30mm normal lowering on a standard suspension and one had the sportier suspension that was
- 15mm the drop would be 15mm . Why would you need a shortened uprated B8 shock when B4 are slightly uprated and can except up to 40mm lowering ?

Hi Gaz I have spoken to Eibach in the past about what shock is best suited to the pro kit springs and they said B8's hence why they are part of the B12 kit so that clears it up for me

Depends on the application and personal preference .

( And if you like yellow components on your car that stand out like a ginger in a playground, lol).

B8 will give the firmer ride .

The springs are the mostly the chassis control and dampers the ride quality .

Eibach Pro & Sportline will accept OE to B8 damping range , think of those better adjustable coilovers that have 30 clicks of adjustment range .

I would be more inclined to go with Bilstein B8 with Eibach Sportline though .

But for those who think you absolutely cannot fit to an OE damper..

And not all Eibach springs are the 'marketing' progressive rate !

Quite often and at a keener price the Eibach are sold with the slightly uprated B4 as a kit .

I know some people don't like being told different but it's not like we're talking about the pikey method of just fitting lowered springs without renewing dampers and top mounts etc.

No, not at all. Forget everything you know about the B codes for Bilstein dampers, they are not the same as for some marques when it comes to the 9-5.
B4 on a 9-5 is equivalent to the basic non sport suspension....... thus the lowest damping rate ie softest. There is nothing sporty about the B4 damper on a 9-5, they are softer than OEM aero dampers.

B6 is an upgrade and firmer than Aero, but suffer with the same issue as the B4 that although the stroke is plenty long enough, they are designed for use with an OEM ride height on the 9-5. With the Eibach springs just at rest they are already a significant amount into the travel of the stroke.

pass, but you won't get them any cheaper than going through Martin........ many have tried!

I will say it again, B4 are not uprated. They cannot and do not control the Eibach springs correctly.
You are correct in that the Eibach springs do give about a 30mm lowering from a normal ride height and about 15mm from Aero.
B4 can in theory accept up to a 40mm drop, but it is not recommended. You will end up with far less damper travel than is really necessary for spirited driving. The dampers will not have enough stroke to do enough work against the compression and rebound to accurately control body movements. Hence the car will handle like a pig.
B6's being firmer will cope better, but the tried and tested best combination is with the specifically designed for lowering B8's. At rest they are much closer to the top of their travel, thus when the car is being driven have the full range of movement throughout the stroke available.

The combination works, it's not cheap, but it makes a very positive difference, even to fresh OEM suspension.

Thanks for all information, the description of the springs say they fit the 9-5 2.0 - 2.3t would these fit my car, just wondering as it doesn't actually specify the Aero

Eibach only do two sets of springs for the 9-5. Saloon or Estate. Front springs are the same rear springs are different. The estate is heavier at the back.

One more quick question how much lower is the 2008 Aero over original suspension

Not a lot. I posted of mine last night. It’s about 10mm down on an Aero.
