[QUOTE="chrish900, post: 9118282, member: 59419"] Thanks for the SCCA specs. The L-plates are what I was thinking about. I was also thinking of increasing the size of the feet on the rear bars as well. The following is from NASA's CCR. It is written for 6 & 8-point cages in their race classes, but the plate rules for bolt-ins apply to Time Trials as well. Per NASA's CCR: 15.6.14 Mounting Plates Each mounting plate shall be no greater than one hundred (100) square inches and no greater than twelve (12) inches or less than two (2) inches on a side. Welded mounting plates shall be at least 0.080-inch thick. Plates may extend onto vertical sections of the structure. Any mounting plate may be multi-angled, but shall not exceed one hundred (100) square inches total including vertical sections. Each mounting plate should have an area of not less than nine (9) square inches. 15.6.14.A Mounting Plates – Bolt-In Cage The attaching points of a bolt-in cage to the body must use reinforcing plates to sandwich the body. At least three (3) bolts are required for each bolt-in plate and the plate must be at least 3/16 inch thick. All hardware must be SAE Grade 5 or better with 5/16” diameter minimum. All nuts must be held securely by a locking system such as safety wire, lock washer, Ny-lox, or jam-nuts. [/QUOTE]
