Anyone roll an FJ?

OK, I know the clinometer stops at 30 degrees, I have had mine at about 28 degrees, so does it tip at 30?
What about with a 3" lift?
 
The clinometer is a fun little ball for the kids to point and laugh at.

If you're using as an accurate guage, I'll see you at the bottom of the ravine one day!!
 
We are all still looking for a guinea pig, please do roll yours and let us know how the inclin-o-meter worked. You will be remembered and revered forever if you do this.
 
There are too many factors tires,angle of attack, center of gravity, terrain, speed, brakes usage etc) to tell anyone at what degree YOUR FJ will roll like a ball. We had ours off the scale this week with tires aired down, 3 inch lift and running 33's. I would say 32 degrees. We had a long down hill at 38 degrees. Actually the little ball works well except for the constant rolling. We stopped and used a magnetic inclometer on the hood and it was within 1 degree.

If you are unsure, take a off road class like at Hungry Valley in So Cal and they can teach you what to look for in the terrain, your vehicle and your driving style.

Earlier in the year someone posted an FJ that had rolled and it did quite well for the people inside, although the FJ was rounded. The roof stayed fairly intact.

I saw that one first hand. It held up amazingly well. Three inside were fine - only sticky from the contents of the cooler in back.

He rolled it in Mexico and drove it 600 miles back to San Diego.

I don't personally have one, but my buddy has the "tilt-o-meter" on his dash cluster and we pegged it a few times while on Hell's Revenge in Moab without rolling. That was strictly going up or coming down a slickrock face, not off camber (sideways tilting) stuff.

Moab is certainly different than a lot of muddy, rocky, root covered trails. As long as you are easy on the brakes, coming down a big sheer wall was as safe as rolling through a parking lot. We often used the parking brake in conjunction with the foot brakes to reduce the amount of front disc brake compression.
 
the Trail Team edition prototype that was used for all the advertising was driven at a 30-degree sideslope during the photo shoot...once both right side tires were on the log, it felt VERY stable....but until the right rear got up there, it felt "unstable", but not tippy....

as noted tho, your pucker factor will kick in WAY before you'll think to look at the gauge....BigYellow is correct, too many variables to put a value on it.
 
Pucker Power!!

Human pucker device is much more accurate than the ball in alcohol!

There have been a few pics of rolled FJ's off-roading (the aftermath) and a video of some Russion guys doggin' it in a FLAT field who manage to put it on it's side.

But I doubt anyone has or will note the guage reading when they reach the tipping point.

Only if it was a manufacturers defect that caused it to burst into flames. Is this the next thing that less then 1% of the owners will start complaining about as if it's a design flaw of some kind?
 
Roll Angles...

As stated above its hard to get scientific about that, and your a-hole should keep you upright in most circumstances. But for subjective purposes I will tell you that last summer we did a big road trip and had the ARB full length roof rack LOADED, with Hannibal tent, food, kitchen gear, kayaks, etc (about 300+/- lbs). On the road between Ouray and ToHellYouRide, we tested the limits of the roll angles with all that gear up there, the lift and larger tires. On the side angle the clinometer read angles well over 30, and I drove very slowly to avoid ANY bounce, and on a steep hill we were slowly ascending the front wheels momentarily lost contact with the ground at about 35+ degrees. Both well beyond the roll angles listed in the owners manual, but that being said, I remind you I was moving VERY slowly and cautiously.
