does your car have a headlight level sensor? (not sure if halogens do) if you do have it, just make sure u install it back to its original horizontal position, instead of vertical. (driver's side front corner)

thats the only "specific" thing i can think of... everything else is pretty straight forward.

1. Decide whether or not you want to un-bolt the inner control arm bushings vs. the outer on the rear. Getting those bolts back in on the outer is a pain. But if you do the inner, you will be playing with your camber.

2. Be sure you put the right nuts (use locking on the rear) on the shocks. Long story on mine...just sayin.

3. Be careful when taking out the bolts from the top of the shocks in the rear. Those washers/nuts can fall down in your wheel well and you'll never get the washers out.

4. Have the diagrams printed out for front and rear for where everything goes back in. I guess you don't necessarily need this for these coils though.

5. Have in impact if you can. For de-compressing/compressing the spring compressors when you get the springs off. And for removing/tightening the top nut in the front. Again, make sure you check the nut on the sonic shock before tightening.

6. I had these coilvers before. Make sure you get the springs good and tight in the front with the rings on the bottom (I guess that's what they're called). Otherwise, you will hear clunking.

I did all this myself (neighbor helped a little at first). I'm far from handy with this stuff and this was a big project for me. If I could do it, anyone can. But after doing this myself, I realized that no one should let anyone else do this for them. Because there's nothing "Technical" involved. And it's awesome knowing how everything is setup. Your suspension is such a sensitive part of the car. If anything comes loose/etc. in the future, you know what to do, ya know.

There's one thing that I'm struggling with right now. And I'm curious to see what you find with this. You'll notice when you tighten the rear top and lower nuts, you can never actually get them to the point where they won't turn. In other words, when you tighten the bottom nut before you put the top part up and in...then you tighten the top nut, the top part of the shock (dampening) turns with the nut??? I'm wondering if this is normal?
