dude, i work on my skyline and micra, the micra is a peace of piss compared to the skyline lol.
My mechanic was over my house doing the suspension, if we had had all the parts (we had to go to the shops to get get stuff) we would have had it done inside an hour and a half.
Just make sure you get some good spring compressors, we didn't need them putting the lowered springs on (just make sure you have a mate to help push them down when you put the nut on.
As for other purchases, i'm going strut bars and panhard rod next.
