Ive read that Mac have supposedly stepped up their effoert in producing better parts overall, especially with their headers. It seems that more mustang owners are going with their LTs as they have some of the best ground clearence in the market, moreso than Kooks, stainlessworks and American racing. Hard to believe, but as far as the pics Ive seen (many) Macs def has the edge in ground clearence for sure. They might not last as long as the others, but who knows. Any thoughts on the subject?
