DIY Coilovers Install
Hey guys, got some Tein Street Basis Z's and figured I would make a write up installing them. It took 8 hours total with 3 people, keeping in mind it was our first time installing coilovers. Only thing that gave us trouble was not having the specialty tools, but we found ways around that. Hope someone can use this thread to install their own coils.

Step 1:
First, safely jack up the car and check that it is stable. Then, remove the wheels from the car.
Step 2: Remove bolt from ABS speed sensor (42 ft-lbf).
Step 3: Remove upper control arm pin and bolt (64 ft-lbf).
If you do not have the specialty tool, like us, you can remove the pin and loosen the bolt until it is flush with the stud. Then use a hammer to knock it loose and remove it. We used a metal rod so we didn't have to swing a hammer around all those suspension parts.
After it is knocked loose, you can use something like wire to hold everything up and out of the way and also to keep the assembly from falling.
Step 4:
Remove sway bar nut and bolt (41 ft-lbf).
Step 5:
Remove bolt and nut from bottom of shock absorber (116 ft-lbf).
Step 6:
Remove 3 bolts from strut tower (41 ft-lbf).IMPORTANT: If you're reusing top hats, loosen the the piston rod lock nut, the center one, before taking the shock absorber out. Do not take the nut off all the way, just loosen it. This is because it will be hard to break loose once the shock absorber is out.
Step 7:
Remove the shock absorber. We pulled it out underneath the brake line.
Step 8:
Take some time to clean your parts up, then, install your coils and follow these steps backwards.

Step 1:
Remove trim above the wheel well in trunk.
Step 2:
Remove bolt connecting the 2 lower suspension arms (55 ft-lbf).
Step 3:
Remove 2 bolts on main lower suspension arm (both 81 ft-lbf).
Step 4:
Remove sway bar bolt (22 ft-lbf) and let main lower suspension arm dangle out of the way.
Step 5:
Remove 3 nuts on strut tower (47 ft-lbf). Loosen center bolt if you're reusing top hats, do not remove it. We had to use an adjustable wrench to hold the piston in place, it just wanted to spin without it.
Step 6:
Remove 2 bolts on shock absorber (13 ft-lbf) and remove it. To Install your new coilover, follow these steps backwards.

After you're done
Make sure to double check all of your bolts and the bushings while you have your car on jacks. Once you have double-checked, put your wheels on and carefully lower you car. You will need an alignment ASAP after coilovers or any other suspension mods, don't put it off. Thanks for reading and if you have any questions feel free to ask!

I have the same setup, really enjoying it. Can go much lower, but its at the height I want for functional daily driving.

Ya we have similar taste . Even our style of wheels is similar. Yes they are just the cheap power stop pads and rotors. Decided to paint calipers while I was at it.

I'm loving my powerstop kit, the best feeling is being confident in your brakes. It's saved me many times
