: Eibachs?

04-15-13, 09:28 AM
I just got my Eibach Pro-Kit and will get it installed sthis week! This is for a sedan with stock size tires so my question is for those that run Eibach springs:
Should they be cut 5" or not? I've heard both sides of this discussion.
Should the bump stops and dust covers be removed also?
I'm just a little concerned that if I don't get the springs cut I might not notice much of a lowering difference but I don't want them cut if they don't need to be.

Eibach says you will get as much as an inch of lowering from the springs as-is (after the springs have settled slightly), if I recall correctly.

The dust cover issue is up for debate, but with an otherwise stock vehicle - my opinion is to not cut the springs, don't cut the bump-stops (I still don't see why cutting these are necessary), and the dust covers are optional but may contribute to noise.

Although no one wants to do things twice, you could always cut the springs later if you're unhappy with the 0.6 to 1" of drop expected - versus cutting now and having an issue with the height relative to your roads and expectations.

Please report back with your experiences regardless.

It goes in tomorrow and I think I'll go with uncut for now and adjust later if I want more of a drop. I'm not into "deep drops" and I hate the ideal of hacking anything thats brand new.

cut em if you want a slight rake. the flat stance is queer imho. why do things twice? cut bump stops and remove dust covers or you'll be paying double.(unless you're doing it yourself) mark my words.

The stock Eibach kit gives approx. a one inch drop on a Coupe, which is just about perfect with the stock wheels.

Stillborn yousr looks pretty good.

damn skippy! lol ty. 5' cut, no dust covers up front, and cut the bump stops. no noise, no issues, corners tighter, and i love the stance. let us know how yours came out today. (post a few pics)

I got them on and it came out better than I thought but they were not cut! There was some confusion concerning where to cut (off the coil or the spring length) so I told them to just install without cutting. I didn't want my springs ruined. I plan on letting them settle and going somewhere else to get the job finished (dust cap/bump stop). After I get this thing cleaned up I'll post picks but I do like the stance. I'm at 27.25 in the front but it looks lower than that.

Why cut the bump stops unless you're bottoming out?

Put a dab of silicone on the bump stop, and see if you deform it before cutting them. ! )


Eta: you cut five inches of linear coil length as the springs compress. Cutting 5" vertical height is a pretty big jump!

Do not cut the eibachs. They are a progressive spring, it's highly advised and pretty well documented not to cut them.

If you want to cut springs up, cut the stock springs. They are liner springs and do not have a progressive spring rate. The maintain he spring rating across the entire spring.

A progressive spring is just that, progressive. It's designed to ride decent at normal height(driving straight)but tighten up when compressed(taking a turn.) When you cut the spring you ruin the way the manufactor designed the spring to work.
