I dunno how capable they
really are ... but in the videos what I see are drivers who don't know what they're doing. The first video shows a guy who thought he was clever, tried to do a Uturn instead of a "K" turn & got his butt whipped ... and he was losing anyway. I got no words for the guy who floored it into a very visible tree. Then that silver FJ ... jeez. I mean I'm no expert, but ... who tries to crest a hill that has a lip at the top by sitting right under the lip & gunning the motor?
Here's how it's done, LOL. Nasty lip at the top .. see how it launched the XJ. The weekend yuppies need more practice ... or a Jeep.
The FJ Team came to OHV at Paragon back in '05 to show us Jeepers what an awesome product they had. My XJ on 29" Revos, open D30, stock Limited slip & 3" lift went everywhere they did with whatever they were equiped with, including some pretty large tires. Some of us got to drive them (not I), but I didn't see 1 jeeper who was running to go trade in their Jeep.
On the other hand, I think they look cool.
