Makes sense, spacers and cheap studs. You can tell the black is more powerful and is just a better build. I too like the converted Camaro's to Firebird's. Although they still don't cover all the Camaro's flaws.
I considered having my 5th gen Maro converted by TransAmDepot a few years ago, until I considered that I could buy a ZL1 for less than the cost of the conversion.
