Its a shop thats local to me that does VERY VERY good work. They have a mustang that the cage is certified for the 8's that they run almost every weekend and have a bunch of 10 sec cars from mustangs to supra's. Tony the lead mechanic is very good at welding cage's so I dont know if this would be worth it, but if you need more info shoot me a email at Jason300zxTT@AOL.COM
