I'm assuming your talking about your ke70 ;]
What are you doing with the car? Drifting? Track? Daily?
Coilovers are good for front low.
Cut some king springs for the rear, and some short stroke shocks, munroes are good. You'll need to cut the bump stops.
The coilovers shoul come with the knuckles if they're any good.
Xt130s are good for 1degree camber. Sigma LCAs for 3 degrees.
Ke30/55 LCAS are almost exactly the same, just need to bash the lock stops off and they cost a third the price and much more abundant.
Lock spacers aren't needed unless you're a drifter or want to do crazy good U turns.
They also wreck the rack seals, no point for a daily.
Panhard is a must if you're lowering your car, keeps the diff in the centre of the car.
EDIT: I'd recommend a rear sway bar, makes the car feel a lot more solid, when going too fast around corners.
