For me: #1 = (SN95)Cobra, #2 = Cirvini Stalker
I used to have the stalker and I was slightly annoyed with two things with it: the fitment at the fender and the underside support. It didn't have a smooth transition to the fender like the stock bumper, it stuck out a bit on the sides and would have taken a skilled hand and some fabrication to get it perfect. On the underside support, the bottom is supported by heavy gauge steel struts bolted to existing holes in the frame to the bumper. Numerous times it would scrape on a steep driveway, sheering the bolts holding them on. At least three times I had to re-attach the bottom supports. BUt hey, it looks pretty cool though. Next time I'm going Cobra.
Here's a Stalker bumper. NOT my car, but you get the idea.
