Perhaps this should be under the bonnet but I figure all the experts are in here considering the topic.

If your gonna DIY install coilovers, rear sway, camber plates, and control arms and try doing it all on the same install - In what order should the install go?
Since the rear is gonna be the most work - could someone suggest any tricks or advice - will be greatly appreciated.

It will be an all day install with my friend and I'm planning on taking pics while I'm at it. :impatient

 

On a lift or your driveway? Makes a big difference...driveway = one corner at a time. On a lift, remove everything in the reverse of logical assembly, and then re-install in the same fashion.

Final torque swaybars and control arms (assuming you have rubber bushings Onasled) after the car is at final ride height.
