DIY Coilover Install

Installing coilovers on a car is actually a lot easier than it looks. It basically turns out to be: jack up the car, remove OEM springs/shocks, use the same bolts to put new coilovers in. I suggest to know what dampening settings you want, so that they can be adjusted before the coils are on the car. This is written for a 350Z, so not every step (like the strut bar removal) will apply. Also, if the rear coilovers look the same as the fronts (spring and shock together), then you will need aftermarket camber and toe arms. Unfortunately I only took one picture while I installed mine, so the ones I found aren't the best

Front Coils:

1)Start by removing the strut bar, to have access to the 12mm bolts UNDER the hood. Remove those too

2)Work on unbolting the 17mm bolt with the red arrow. Using an impact wrench is very useful here.

3)The end links (green arrow) will need to be removed to get more clearance. 

4)Now loosen up the bolts holding the A-Arm. This will let you have enough room to remove the old shocks/springs. 

5)If you bought aftermarket A-Arms, this is the time to put them in

6)Replace everything with shiny coilovers

Rear Coils:

1)For the shock its the same as in the fronts: remove the 17mm bolt from the end and the 2 12mm bolts at the top.

2)The spring bucket needs to be removed next (green/blue arrows). The spring is then going to pop out, be careful.

3)Where the spring bucket was attach toe arms

3)Put coilovers in..

Not the best write up, but its pretty straight forward.
