This is a four-point roll hoop with rear backstays and is sold as a weld together, bolt-in kit. The main hoop attaches to the seat riser/inner wing. The backstays pass through the rear bulkhead panel and attach to brackets located above the rear suspension. The main hoop is 50mm with a single diagonal brace. Cannot be used with a soft top; a factory hard top will fit over the bar however. Professional installation by a competent welder is required. Painting required.
