Re: miata roll bar
1/8th wall seamless mild 1.75" od
the dude at the metal shop we buy all of our stuff from at work said its what all the locals use for their roll cages so i would guess itd work well for this. feels a little thinner than the sch 40 manifold tubing accually so i think itll hold up just fine. esspeically with the tri point top corners that will see all the stress in a roll over.
busted my *** keeping the weight out and this was about 55 pounds

Re: miata roll bar
funny how they can turn you around for this and not having a bar is fine in some groups. i wasnt really concerned with passing as much as looking at what they want so i know when i can consider myself to be safe you know.
for mounting my meathod will be to set it in the bar on some 1/8th inch plates that are pre drilled and then take out the bar and drill the car and backing plate and bolt them all in then set the bar back in and weld to the plates. should keep it all lined up right and have the best fitment that way i would think.

Re: miata roll bar
yea the rear two support the main hoop it will have 4 mounting points. the two rears should keep it from collaspsing. all of the scca legal bars use 4 mounting points. dont really know how you can put any other support bars in unless you did a full cage to the front of the car.
