Just going to the firewall sheetmetal doesn't properly triangulate the chassis for coilovers. Have to go from the main hoop through the firewall to the rear gussets. In my case we went through the firewall with 1.5" x .120 DOM from the top corners of the main hoop to the rear reinforcing plates as seen in the pic in my earlier post, then welded .125" plates around the tubing onto the firewall to properly seal the firewall back up. And yes my cage is probably overkill. Oh, and it's white now too. At one point I wanted the entire car Ferrari Fly Yellow until my wife discovered the paint was $800/gallon and decided Glacier White was much better.
