I'm personally not a body kit person...but mine came with the cyber kit so I'm sticking with it, though I picked up a stock front for winter.
Bigger question is availability.
-Cyber was the only kit made to my knowledge and didn't fit the car's style, most are gone, as they don't hold up very well (i.e. thin fiberglass).
-JDM stuff occasionally comes up for sale, but its normally pretty pricey. I personally like there front ends better, but its a matter of opinion.
-CF hoods (w/ or w/o JDM vents) can be had new and look sweet, but they're pricey.
-then theres all the misc stuff that works like R32 wing, Saab rear bumber, 89' tail lights, ect.
-or the hack and mod of factory parts. I personally think the front grills look good cut out on the factory bumper. A small lip on the bumpers look nice too. Someone posted how to make those out of the section that goes between the bumper and the grill/lights.
