Eibach lowering springs... which struts ?

Then why do they sell the bilstein hd/eibach kit if they don’t work. 😂

That’s an excellent question...

It is called capitalism...

FYI, I just opened my H&Rs coilover struts and the bump stop was even longer than the OE one (70mm vs 45), for a system that drops the car an inch it makes no sense. Again, it probably was “tuned” that way, but that doesn’t make it optimal or compliant.

my car with new linear springs and modified bump stops ride better and it doesn’t bottom out, I gained 1.25 inch of travel from road ride height to touching the stops, whereas before I was constantly riding on them (even when my ride height was set to stock), at 1inch drop I would be well into the stops. This made the ride very bouncy

H&R coils are Bilstein shocks (they are even stamped with Bilstein branding)

there is no way around this, and people who say the ride fine are lying or they ride on smooth roads. Stiff damper, plus stiffer spring plus riding on the stops cannot be compliant. Stock, the car has at least 1/2 of travel before engaging stops.

take it apart and do some measurements and math and you will see.

and to the question above, imagine mine was a coilover kit, and had all this flaws, the B12 is nothing more than a parts bin setup, that “matched” thing is marketing BS as both parts can be had separate.

I feel that I should have bought the Eibach sport kit.
This is a true matched damper/spring combo as opposed to the B12 marketing exercise.
I shall shorten my B6 bumpstops in the interim although they serve as an additional damper.

What about ground control camber plates, will that help with bump travel? I mean it rides great as is but bumps suck that are over 3”

This is the B12 on 18's

Here’s mine in bilstein HD and Eibach Pro Kit springs. On 18’s how it currently sits 😐 and when it looked nice on genuine CSL’s (until they cracked about 3 different times on the rears and I said f*ck it and took them off as I’m tire of welding them/replacing them)

No, they only change the overall height of the complete strut assembly, typically lower VS stock, so if shorter, you can lower the car without affecting travel.

When I did koni/eibach sport kit I was advised back on M3F to add the GC camber plates to gain back +/-1" inch of travel with that setup which I did. I can say it never hits the bump stops over rough roads.

But that gives you more travel at the same ride height vs. stock mounts. I've recaptured almost an inch with TMS plates vs. stock. That allows me to sit at 13.5 and have the same travel as stock.

I did a lot of sketches trying to understand why a camber plate gives travel, I will post it so I can be shown what I missed, I just couldn't understand how.

[Tbonem3]

You're moving the top of the strut shaft upwards OR you can think of it like pulling the car lower without compressing the shock shaft (no loss of travel).

So my struts don't even compress much at all with the car on the ground. The springs are 7" and pretty light at 325, so there's lots of sag, but that's on the spring. And that large amount of sag gets me to 13.5" ride height. Then, loaded, the spring compressed, I still have a "stock" amount of strut shaft travel and because I have a 7" spring, It won't block or bind on me through the full range of travel.

that is not travel, I get what you are saying though, what the plate gives you is the height you were looking for without having to go to a shorter spring (or lowering the perch too much) which eats bump travel; the total travel is defined by the length of the shaft length, which you split between bump and droop, you need to make sure you leave enough for bump, if we slam the car just because via springs or coilovers without taking travel into account you end up having little bump travel and constantly riding on the stops.

with this I agree, we are saying the same thing

[Tbonem3]

Well, you can't get more travel than stock, that's dictated by the strut. But what you can do is modify your stack so you're not compressing (much, if at all) the strut at rest.

Most setups COMPROMISE travel. With what we've done, we're not making more travel, but we're not eating it up either.
