^^^^ Totally agree with what chmercer said.
I run KTS coilovers, rear heim jointed arms and full poly subframe mounts (not spacers or collars). It rides beautifully, very solid and comfortable, even the girlie agrees. I also have the Nismo motor mounts, and the tranny mount which I filled with poly as it was still too soft (shifter would wobble all over the place when I broke traction)
The only thing I found too harsh for my tastes as a DD were heim jointed front tension rods, I swapped mine out for stock arms with the Nismo bushings instead and was much happier.
As far as wheels and tires, it's 17x9 +20's all around on 235-40 rs2's (love these tires!)
1.6 degrees camber and 0 toe in the rear
1.5 degrees camber and .04 toe up front
(completely stock fenders front and rear, no rubbing.)
I think this should answer about every question you could ask about my setup
