This is what AGI had to say. Also Is there any big deal using a standard wrap around style harness rather than eye bolt style as the first pic shows the cage but with the eye bolts added which is a $120 option. Hi Dan, Thank you for your interest in our Bolt-in Roll Cage kits for the Nissan Silvia S13. We have a number of options depending on what level of competition you’re aiming at. See breakdown below for our 2012/13 CAMS approved Bolt-in Roll Cage kits for the S13 model. I have also attached some sample photos for your reference. Please note due to high demand at present (start of the racing season), lead time for a bolt-in kit is 2-3 weeks from time of ordering. Please advise if you’re competing before that date and we can look to have your cage ready in time so you don’t miss your first event. Shipping to Wodonga including wrapping, packing and crating a half cage kit is $140. Options: A) Half Cage (4 point) Bolt-in – Main Hoop, diagonal brace (through hoop), backstays and harness bar.
