Not sure of the part number(s), but these are Pedder's Xa adjustable coilovers. I got them from another forum member - mistercamaro69.
The ride quality is very similar to stock, maybe just a little tighter, at the settings i'm using now but this is adjustable.
The body roll is practically none - but I also installed Pfadt sway bars at the same time as the coilovers.
The best part with the coilovers though is having the car corner balanced. After scaling, the car feels very neutral and somehow lighter. This seems to really improve the handling and fun factor.
The car is dropped about 1.5" or so, corner balanced, and aligned with a little negative camber.
