Eibach Pro Street S Coil Overs vs. KWV1's!!!!!

OK...dug out some info for the comparison between KW V1's and the Eibach Pro Street S coil over kit. There are some differences between the KW V1's and V2's which is the V1's do not have adjustable rebound dampening.

Remember, there is some difference in materials used between the two brands and that's already apparent in previous posts.

Here's some tech data + pricing and install costs:

Analysis:

Do I need the more corrosive resistant materials found on the KW's or not? I do not live in a salt air environment nor do they salt the roads, or use corrosive liquids, to melt ice and snow here. So, I am fairly certain I do not.

Is the material used by KW inherently stronger than the Eibach materials? No telling. The material specs are not available.

Any major differences in spring rates? No.

Any major differences in lowering rates? Yes. The KW kit will ride higher based on the specs above. The Eibach kit has a greater range of adjustability. I've seen a car with KW's on it and it is loooowwwwww...so you may not need all the adjustablility available with the Eibach kit.

So, there you have it, folks. What I was able to find.

Hope this helps!

 

very good info!!

 

For me personally, the *minimum* drop was of interest and definitely rules out the Eibachs (crap, maybe even the KWs). dammit, why can't they make a superior replacement that would accomodate the stock ride height?

 

Dam, Mike thanks for the information.

I ended up buying the Eibach and should have them installed within the next two weeks...............

 

When do you think they will get in?

 

Sorry Drewy,

I just found out that they will be in next week.................................:deshade:

 

My sways included I assume?

 

You would be correct my friend along with everything else...:clap:

 

what "else"????

 

Unrestricted use of Ryan's grease gun... good for bushing and oral lubrication.

 

Don't you still have that?

 

MOMO I don't want to hear about your wet dreams..........:huglove:

 

Dream Weaver and BUTT irate:!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

What do you mean "hear"... you've already tasted them.

 

RICE CAKES! No flavor and will never fill you up..............

 

Just to complete the research, I looked into the Tein system with their EDFC (damping control) and found:

Tein System DSJ68-KUAS2 www.tein.com
Tech Data
Adjustable Lowering - Front .3” – 2.5”
Adjustable Lowering - Rear .4” = 1.9”
Spring Rate - Front 671 pounds / inch
Spring Rate - Rear 783 pounds / inch
Retail List $1,350.00
Add EDFC - control the damping force at the touch of a button while in the driver seat. This is accomplished by controlling stepping motors installed on each shock absorber. $380 – Total with EDFC = $1,730

So, the damping force is adjustable from the cockpit vs. having to get out, get underneath and adjust the KW V2's.

It's my opinion that adjustable damping force is a waste unless your car is a race car on the track most of the time.

But hey..what does a noob know? LOL

Hope this helps.

 

You're welcome, Ryan. Let us know how they work out for ya!!!

Glad I could help. Sorry it took me so long but digging some of the info out of Eibach was like pulling teeth. :viking:

 

Ooooh, I think I could live with the Tein's. .3"/.4"

 

I'm thinking out loud here, Chris but I would expect that there are some inherent differences, such as:

1. Material Specification - Stainless vs. Powder coated steel, steel alloy specifications on the springs, etc...
2. Damping Rates - Fixed vs. adjustable and those fixed values across the offerings + valve orifice sizing (controls damping and oscillation), fluid specification and dynamics. There's others, I'm sure but I'm no expert.
3. The aforementioned spring rates.

For me it boils down to the cost/benefit. What does the set cost, do I need adjustability and do I need a higher quality steel. (KW vs. Eibach vs. Tein).

So, unless there's a supplier that can beat the Eibach price on a set of KW V1's, that's probably the direction I go.

Now...Ford vs. Chevy vs. Chrysler vs. all the others...not gonna go there. LOL

 

Well all I can say is the Eibachs have been track tested and SRT8U approved!
