Auto X & SCCA guys I need help

[SHOdude]

So I'm looking to buy a roll bar for my miata through s&w, the rep said for SCCA/Drifting I need 125 DOM but from what I'm reading 95 DOM will be fine for my miata because its under 3500lbs, They have about a $200 difference and I dont want to go through the trouble of doing it twice so I need help, I looked for road race rules but it seems different tracks have different rules, Any input?

phillyscca.com, ask on the forums there. there are only a few people I would trust on this site with advice like that, and they dont seem to lurk around that often. they also have a fb page under the same name
