The Boss Frog Double Hoop Miata Rollbar is made of the highest quality 1-3/4" x 1/8" wall DOM tubing, with heavy 7 gauge laser cut flat parts. Each rollbar is manufactured in a precision welding fixture to assure the absolute best fit in your car. They utilize TIG welding for all tubing joints, to provide a higher strength but yet smaller weld joint, and the highest quality finished appearance.
Why don't their competitors use TIG welding? Because it is slower and more expensive to make. The Double Hoop Miata Rollbar is available in three finishes; Black powdercoat - after manufacturing, the rollbars are shot-blasted to remove any mill scale from the steel, then they go through a 7-step cleaning process, then a 60% gloss powder is electrostatically applied and baked at over 400 degrees to get a hard durable finish. Polished Stainless - high quality 304 stainless tubing and flat parts are hand polished to a shiny finish. Unfinished - the color and finish of the rollbar is completely up to you.
The secret to the Boss Frog Double Hoop's strength is the unique saddle, which straddles the Miata's "hump". In rollover testing per SCCA guidelines, the patent pending saddle design helped to distribute the load to the floor of the Miata. The vehicle frame bent in half from the pressure, but the rollbar was completely intact.
Why buy a Boss Frog Double Hoop over other Miata rollbars? The only Miata rollbar to be physically tested for strength, isn't that what you are buying it for? The only Miata rollbar with TIG welded joints allows a much smaller, yet stronger weld for the best possible finish. Best installation instructions available anywhere!
One question commonly asked is "How do I attach a harness"? One way is to attach a harness is to wrap it directly around the rollbar. The Boss Frog rear vertical brace is within the SCCA rule of being 20 degrees from the centerline of the seat. This means that harness straps can be wrapped directly around the vertical brace, just below the diagonal brace. And the best choice is the BossFrog Bolt In Harness Bar
Retail FLAT RATE shipping of $65 applies to these rollbars and they ship factory direct to you. Although our store will charge some lower shipping amount we will correct the order to the flat rate in the lower 48 states of $65 because that is what we get charged too for the shipping on these.
BRIAN'S APPLICATION NOTES: This new Maxx design has a rake angle on the top portion which positions the hoops about 1-1/2 inches further rearward for increased headroom and recline angle. In order to fit under softtops, the overall height of the Maxx design is about 1/2" lower than the original Boss Frog Double hoops. Because of this lower height, some customers will want the old style (standard) hoops, to get the tallest possible bar for track use and helmet clearance. Therefore, Boss Frog continues to offer both styles, the Maxx and the Standard.
