HOW TO: Eibach Pro Kit Spring - Install

[Bart-man]

*Original Post by s0madlan*

First I started with the rear.. Jack up your car and put the rear on stands, both sides.. Take both rear tires off.. Then go into the trunk...

Take those off cuz thats where the nuts are located which holds the springs..





Same with the other side, but the speaker is in the way, so you need to take them off..









Once, you got those out and can see the nuts in there JUST LOSEN THEM AT FIRST!!

Next you go behind the brakes and take that off..




Once you took it off, go back in the trunk and undo those 3 nuts. The springs may fall off on the ground... Mine didn't so you just push the bottom part of the springs hard and they should fall out easily.. Now use your spring compressor (do this for all 4)..





Next you unscrew the top part and you'll need these to help take it out.. When you unscrew them the top and bottom will move so make sure you pay attention to how they line up cuz you will reinstall them after replacing the springs.. If they are lined up incorrectly you'll have to do them again for it to fit properly..

size T30 for the back struts, T40 for the front



Here is your bumpstop.. You should cut it at least half an inch.. Some people do more, some do less.. So you figure that out..





Now it's time to do the front.. So jack the front end just like how you did the back and take off wheels.. Then pop the hood.. Look for these on both sides and loosen them just like how you did on the rear..



Next look at the front brakes..


First remove nut (1)

Remove 2 screws holding break lines on both sides (2)

Support the rotor with a jack (it relieves the stress on it after last bolts are removed)

Remove the 2 two largest screws connecting springs to breaks (3)



Then do the spring compressor again like above.. And reinstall...

After about a week or 2, make sure you get your car aligned...

EDIT:


Here are some more pictures, detailed of the springs that MikeW had with road race engineering.. He also said that removing the nut on top of the springs comes off easily with an impact wrench.. I tried it and it works a LOT better than using that tool I listed above.

FYI for anyone doing this install. Double check the strut tube. Last night we did a friends eclipse gt. The strut needed a 6mm allen key not a t40.

can you check this simply by opening the hood? or do you got to remove it then check? and did you use a T30 for the back?

It's not a hex...it's definitely a torx star...

You don't need it for the springs, though. And you don't need a spring compressor. Do get an impact wrench, though.

Put the entire assembly on soft ground or grass, facing away from you. Then take an impact wrench to the nut AROUND the torx keyhole. I believe it's a 17mm deep socket...might be wrong... Anyway, the assembly will pop apart, and the spring will bounce out a few feet. You can then use the impact wrench to put it all together. Just sandwich your new spring inside the assembly, line the elements properly, and it will come together without a hitch.

I also had issues with the BIG nut/bolt on the front struts... I believe it was 22...or maybe even 24 mm... the one that needs roughly 225Nm torque. I had to use two wrenches, one to turn and another to keep the bolt from spinning. If anyone knows an easier way about this, do tell.

i did the backs so far and i did use a spring compressor....did not need a torx bit at all...i stuck an allen key in the hole to hold it and used a 17mm open ended wrench to take the top bolt off. it was pretty easy and ill be doing the fronts in the morning

[marksmitsu219]

just completed the fronts. the overall job was surprisingly easy and all you need is a rachet set (make sure u got a 24mm), a compressor and breaker bar. i jus used the handle from the jack and it worked great. overall install took about 6 hours and i would recommend it to anyone. save a lot of money and use it elsewhere. ill be posting pics within a few days when i get a chance to wash it....and this is exactly how it should have came from the factory

This is one of the first suspension mods I am looking to do. Has everyone been happy with the Eibach pro and the progress.

I look forward to the pics.

thanks for your thoughts.

Looks great, did you get the same drop as advertised for the springs?
How dark is the tint?

Very nice ride

[marksmitsu219]

tahnx...yea i got about a 1.5 inch drop...the tints are 20%

Just did mine. Backs were very easy. Allen key fit perfect. (Front and back)

Big bolts on the fronts were tough, but they came off. Needed just short of tool breaking strength to get them off. (Watch your fenders.....and make sure you have a really good socket.....not the time to be slipping off.

Watch when you finally get everything loose while doing the fronts. Very easy to nick or cut the brake lines. I nicked the smaller of the two lines, (anti-lock wires??) but I don't think it went all the way through to the inside. I'll put some really good tape on it for now and keep an eye on things.


Total time was about 5 hours sans lunch. Back still looks a bit high, but then it hasn't settled yet either. Going for a ride tonight....if anything is a miss....I'll report back here tonight.

[Corellian98]

Everything seems fine, except for a double thump coming from the front right side on certain bumps. Tomorrow I'll take the wheel off again and take a look.

Any idea on what it could be......assuming I did everything right. (Although....I'm not above making a mistake)

[joshmbu]

do you need to cut the bump stop? What does this do exactly when you cut it more vs less?
