I hope this doesn't catch on in the states .

Oh heck I did that years ago. Of course I had 1.5 ton of wood in the p/up rated 0.5 ton.

This is what i am doin next weekend

I can't believe it has caught on anywhere. Lots of stresses on components that would make me not want to even sit in it.

[yetibone]

I can't believe it actually rolls.

Knuckle dragger.

Great way to reduce the chance of getting curb rash on the outside of the rim!

Some of the VW idiots are getting into pretty serious camber, they love camber and mexipoke...

[speeder]

That's hilarious. Wacky Japanese.

[Flieger]

I've seen it here.

But we are using this on the FSAE car so it is not bad as long as you have the right tires.

I've seen this in Detroit, but on Buick Electras and Chevy Caprices and Impalas...

AWESOME video Max......thanks! That thing hauls donkey! I love the caution light on top...perfect!

[Flieger]

Caution light is for regulations- high voltage warning.

[dewolf]

Do the tires squeal at speed?

[Flieger]

Yes (when turning at speed).

Serious question: on racing cars, isn't there a point of diminishing returns WRT negative camber? Like maybe the inside wheel gives up all grip or (?) I realise that the cars in the first video have nothing to do with any type of performance, but it got me wondering.

[Flieger]

Yes, if you use car tires. If you use motorcycle tires, not so much.

There are pros and cons to the setup in the video. This coming year I am planning to use the same tires but no static camber, and about 200% camber gain.

Basically you can get the same lateral force from a motorcycle tire through either slip angle or camber thrust. On a motorcycle you need to have some camber (lean) to keep from falling over, but you see riders will hang off the bike to allow it to stay more upright, at least with street tires. MotoGP guys lean like 55 degrees and stay tucked in more for aero reasons. But street tires definately will reach the limit of grip with too much lean, and that limit can be less than the amount of lean needed to counteract the centrifugal force -- which is why the rider hangs off.

Cars use (static) camber to compensate for suspension geometry that does not have 100% camber recovery, which means that the car looses camber when it rolls. They want to keep the tire pretty close to vertical in the turn and use steering angle to turn. Motorcycles use the camber thrust to turn rather than much steering.

[trekkor]

Most track cars are running 1-3 degrees of neg camber, some up to 6.

Those above are clown cars...

The Hybrid is legit. Using what looks like scooter tires.
I'd like to see some more video of that.
