The Regal had a 6 pt cage when I bought it and my understanding was its good for 7.50 or slower in the 1/8 . The new engine went a best of 7.00 throttled stopped around 2/3 travel so I know theres another 1/2 sec in there. Tech guy said I needed more cage. Bought a pre bent kit from ART which was supposed to fit my car but didn't come close. After some cutting, a slight bend or two I got the hailo and the window bars that run down behind the A pillar welded top and bottom. I got 5 pcs of pipe left. Its my understanding one is supposed to go across the dash but being as my factory dash is in place I dont need it. Another two are to go along the bottom of the door but this car has a full frame and again was told not needed and the last 2 are intended to go at a 45* from the hoop behind the seats to the center of the car. There is no solid support in the center of the car only sheet metal. Are they supposed to be welded to the provided plates and then bolted to the floor or hump. Looking at the pictures and diagrams its unclear. Any insight and or pictures would be a big help. I believe its required to have 10 attachment points to the frame and now I count only 8.
