We used the ball joints that came with the kit. My friend looked at them and thought they'd be ok (we'd heard some bad things about some of the ball joints).
The coils are 1" drop coils from CPP. I will be using 1" blocks in the rear. The car sits a little lower in the front b/c of the tires also. The new tires are 195/60/14. I believe the old ones were 75s.
