About that big, maybe a little bigger.

I'll check in the morning when I go home from work.

Yeah don't use that brace.. but it's not the brackets that are the issue, those are plenty strong...

It's the fact that it's a 1/16th inch thick piece of extruded aluminum with styrofoam inside it.

The Robispec bar is 3" OD.

Thanks. I measured the stock bar, one way was 2.94" and the other was 2.84". Was trimming needed to get the plastic end caps to fit since 3" will be bigger?

It almost fits without trimming. I trim mine just alittle bit.

Just a FYI, me and shovelman were talking about the robispec...because of the weight we believe its a thin wall so ill say again, even with the robispec I wouldn't use it. Use a roll cage only.

This is why you keep your airbags unless you have a cage. The airbags will help a lot with the seatbelt stretch (stock or harness).

Really? Interesting.

You drive faster when you are pretty sure you won't die imo.

Robispec is down for maintenance, how long has this been going on for?

Contact him directly. PM him here or call his cell which he posted in the past. The site has never been the primary source.

MAximum downwards incline is 15 degrees - per FIA standards for race restraints. I imagine SCCA has a similar standard
