I need some info guys. 83' El Camino.... I have been looking at the Boss 338 wheels. I have found a combo of 18x8 with 4.5" backspace up front, and 18x9.5 with a 5" backspace out back. To start.. will this size work with slightly being able to tuck wheel front and back or do I need to run 18x8 front and rear? My plans are to run shockwaves up front... not looking for it to sit frame, or anywhere near that, I just want a nice low stance. Also, what size tires do you guys recommend?
