"I'm planning on buying Endura-tech's. I like what Kenchan has to say about them, and I drive my car everywhere, and a lot of roads nearby are bumpy/cracked as hell, so I don't want stiff-ass springs. Besides, I like their website design lol"

Hey thanks for the good feedback on the website design. Let us know when your ready to make that move on the coilovers. I am here to assist you.

 

Can someone explain what spring rate is?

 

My cliffnotes version

How soft or stiff a spring is compressed when made.

Im sure others can give you a more detailed explanation. and what it actually does.

 

Well, spring rate is the amount of force it would take to compress the spring x amount of inches. For example, if you had a 336#/in spring (also known as a 6k spring) It would take you 336 lbs. to compress the spring 1 inch. If that spring was 8 inches in length, it would take 2,688 pounds of force or weight to make that spring solid (also called coil bind), in which all the coils of the spring would be compressed and touching one another.

For all those that would like to know, the calculation to convert a kg to pound spring is this: k / .01785 = #/in. So if the spring is a 5k spring then the conversion would be 5/.01785= 280 #/in.

If you wanted to get really technical, the definition of Spring rate is: "The difference in dynamic force resulting from a spring + and - amplitude of 10mm divided by 2,050 as to obtain the average rate in N/mm for this range." As stated by the "Spring Design Manual 2nd ed."

But to simplify that further, Spring Rate is the change in load per unit of deflection.

Hope this helps.

 

Well my explanation looks like a 1st graders answer compared to that

 

LOL. I just graduated from Jr. High So we have a few years between us.

I just happened to have the more technical comments at my finger tips, but the first comments and the conversion rate I readily hold in my noggin'.

Cheers

 

sorry didnt see this post until this morning 7/16... as far as comfort
there are really no drawbacks. i carry my little ones with me in the
FitS and they have never complained about comfort. Even the wife
said the car felt very smooth. there is really no harsh or stiffer
behavior. was a different story when i had the DF210's. those were
smooth until you hit a bump. most coilovers out there ride fine until
you hit a bigger bump. with the EnduraTechs you can hit a big bump
and still feel fine.

you can set the height of the EnduraTechs at factory, above factory,
or below factory to about a 2" drop. it's a very verstile setup.

 

yah, with the EnduraTechs you dont need to choose which roads to
take. wish i could say that about my modded cooper-s.

 

the endura techs are sounding more and more tempting.

 

Hello,
many thanks for your great answer. Time to look for funds

Ciao,

Stefano

 

Has anyone ever had/tried/rode in a car with AME Engineering coilovers? Locally made in Washington state from aluminum, shock bodies anyhow. Trying to find someone with a ride report on them. I called and they are priced at $985 shipped. He will give you whatever spring rate you desire after he speaks to you, what kind of driving you will be doing. Sounds like it is too good to be true!

 

This could have saved me loads of aggravation dealing with Ellis engineering before I even ventured into doing my other choices as they became available.
I paid Ellis about $650 or so for 2 struts and 2 shocks. Ellis was nothing but broken promises that later lead to failing health, blah, blah, blah.
What's AME's website?

 

who is AME?

 

Just received Skunk2's. Will install this weekend and post feedback. I drive like 800 miles a week so it shouldn't take long to see how these handle.

 

Had Tein Basics for almost a year now, dropped 2 1/4" all around. You can drop close to 3" in the front and 2 3/4" in the rear. The numbers given on Tein's website are their "reference height" which is what the combo was designed to work optimally at.

Ride for the first week was harsh. then it levelled out to a solid but well damped feel. handlign became MUCH more neutral than stock thanks to the very stiff rear springs. Body roll is minimal and the car barely has any understeer, which is impressive for just a coilover set with such a front heavy car.

The Cons are nly height adjustable. Not good enough for serious track use. Great for daily driving and spirited drives.

 

Evidently AME is AMR Engineering and they have a whole bag of issues based on feedback on other forums.

 

Hey Endura-Tech (Justin) I am looking to get those coilovers soon. I can't wait long time coming. Kenchan I finally ordered the the Endura-Tech's can't wait. When TopSpeed does the install plus the corner balancing I will post. Take care

 

Can I see a picture of the drop on your car? I been trying to decided what to get. I rather pay more to get what I want then get something cheaper and regret it later.

 

there ya go.. one pic with Tein drop.

 

Thanks. Is it able to go any lower? Thats kinda what Im dropped at.
