DIY: FRONT Eibach strut springs

Sorry for the long delay, finally getting around to posting the front strut replacement. (so I've forgotten most of the fine details)
1) Jack up the front end, place on stands, remove front wheels.
Unbolt 2 lower bolts securing wheel/brake assy. to strut, wheel assy. will drop away so I supported it on some wooden blocks, remove brake line and upper tie rod (?) connector per pic:

2) Upper strut bolts - mark a strut bolt so you reinstall it in the same location. 14MM socket to remove the 3 strut nuts (I unbolted the brake fluid reservoir and moved it out of the way)

3) Remove the strut assembly. Secure the strut assembly in a vise or suitable device and completely compress the struts using "approved strut spring compressor device"
After the strut springs are compressed completely, you have to remove the upper strut nut off the rod......in lieu of special tool, I used a 17mm deep air socket with vise grip and 8mm allen wrench. (I first used a chromed socket and couldn't get enough grip on the socket so switched to the "iron" socket.) Hold rod with the allen wrench and loosen the upper rod nut, remove nut, remove hat and spring.

4)Eibach spring shown with stock strut spring. Eibach spring has thin plastic cover/bumper ...I removed the heavy grey OEM spring cover from stock spring and placed it in same top location on the Eibach (I assume it acts as a bumper when the strut bottoms out)

5)Reinstall spring on strut, install top "hat" and reinstall rod nut (I obviously could only hand tighten and used Blue Loctite...no problems) Make sure the lower spring fits into the notch on the strut assembly as shown in pic:

6)Release strut spring compressors (slowly) and make sure lower spring end stays in the strut notch. Re-install on car/ make sure upper strut bolts/hat go back to the original location using the paint alignment markings you put on prior to removing.
Install top strut nuts but don't tighten them completely until job is finished and car is back on the ground. Reinstall brake line, tie rod(?) connector and brake assy. and wheel.
SLOWLY lower the car to the ground and keep an eye on the strut spring as it compresses....you may have to turn the spring slightly to keep it in the lower strut notch. Tighten upper strut nuts when car is on the ground and settled. I forgot a few details like all the metric nut sizes and torques (used the Protege5 shop manual online for wheel to strut torques) Only hassle I had was removing the strut rod with make-shift socket and vise-grip and the spring wanting to rotate during reinstallation.
The End
 
do you think you can post before and after pics... to see how low it sits now?
Before picture from different camera angle but you can still see the huge gap:

It appears I can only reply using the "quick reply"...so you can't see both pictures open in the post (?)
After picture with springs installed:
Mazda2 after.jpg
 
Another note: I have about 5,000 miles on the car since this installation and noticed the front tires are wearing heavily on the inside tread. (camber)
No, I didn't get a front end alignment after the strut spring change....but will get one scheduled now. (Rotated the tires for now)
 
Very nice writeup! I like your "make shift socket", lol. Interesting because my wife bought a "go thru" socket wrench set to assemble some IKEA furniture. There is a 17mm deep "go thru" socket that would be perfect because you could insert the 8mm allen wrench down the center of the socket.
 
so i tried installing my RB today, no luck damn thing keeps moving around imma try again tomorrow if i get off early if not have to wait forthe weekend. question with marking the upper bolt Y is it needed to be marked? i looked at the pillow mount its all the samething so no matter how u re-install it it should be the same thing. correct me on this please...

I marked them because I'm anal...and wasn't sure if there was a difference, had no reference at the time.

lol all good, i remember back in my civic days when i installed springs i used to mark them too cuz thats what i was told but as time and technology progress i see no more difference in mounting them back. btw how the F@#K did u get that damn nut loose? a friend of mine helped me he acted like my VISEgrip lol
 
I purchased a second set of eibach springs since i was having the same issue of the springs rotating when being reinstalled and one of the springs would not sit properly in the lower perch. It appears that that eibach has redesigned the front springs so that they now sit better in the lower perch and do not move after you release the tension from the spring compressors. Here is a pic of the the two different front springs. They have the same part number, however the problem spring has "2008" next to the eibach logo and the redesigned spring has "W/V" next to the eibach logo. You can see that there is a larger gap between the bottom coils on the "W/V" spring and the bottom of the spring is more angled to fit the lower perch so it will not move around after you release tension on the spring compressors.

I used a "go through" socket wrench from Lowe's that is hollow in the center so you can insert the 6mm allen wrench down the middle. The wrench comes with an extension that is also hollow in the center.
 
Was anyone able to torque the center rod nut? If so, what tool did you use? The low torque specs (23-28 ft-lbf) given for those nuts suggest a decent tightening without too much effort plus Loctite.
 
How is the ride and handling with the Eibach prokit? Im looking for a stiffer spring thats a lil lower but not to bouncy. Also what is your ground clearance now? Ive got nasty speed bumps where i live

Ride is stiffer and can be bouncy on rough roads....I discussed it in the DIY: Rear springs thread, basically on I-81 near Harrisburg, it started a "light chop" over the concrete pads and got pretty annoying. Overall, the ride is not too bad.
 
Thanks. Im debating between these, the h&r and racing beat springs. Im in gettysburg pa so I know how crappy the roads are.
 
I really need a service manual. What are you guys torquing the strut to knuckle bolts to??
 
Take a look at 'Suspension Torque Specs' about 6-8 threads below. Posted thanks to Joker2

I'd add some blue Loctite also. I tightened from the nut side in case there was drag binding the bolt.

If no torque wrench, the answer is 'a lot'. If it loosens you'll hear a thunk going around corners.

This is the suspension I want to buy.
Im not sure if those are the redesigned front springs. Help please?

What I found out later from Eibach was that the batch I had that was labeled "2008" was spun incorrectly thereby causing the fitment issue. So if your springs do not fit properly, contact Eibach.
