Is -40* camber ok for autocross?

wtf....

That's just crazy. I've seen it before, though. A couple years ago. It does make me think that theoretically one could make a tire with longer sidewalls on the outside than on the inside, and still maneage a reasonable contact patch. Play hell with the bearings.

The best thing about that video is the JDM Forester STi.....

Rough on CV joints also.

OK. I am not one to judge other people's delusions. but what the heck is the rationalization for that set-up? Some one went to a lot of trouble to make that happen and there has to be a reason even if it is not even auto-sport related

It's for better tire life. Once the 1/4" on the inside wears out, you can flip the tires, and effectively have a brand new tire! That way, you get twice the mileage out of a set of tires!

Perfect for driving down sewar pipes/tunnels

actually, I didn't find it on autoblog ;)

I saw this on another board yesterday and I noted there that when the dude said "what the berkeley is that" he sounded a lot like Christian Bale during his tantrum.

Even fully dropped on bags, that is just going way too far. Too much of a good thing.

Someones doing that and trying to sell it to SCCA autocrossers...

Camber Tire

That doesn't make any sense. As soon as you turn, the tire leans towards positive camber, hence the need for negative camber. If you run 3 degrees negative camber, and the tire leans 3 degrees towards positive in a corner, the tire will be flat on the road, and the car will handle better. The "Camber Tire" will completely remove any benefits of negative camber, and put you right back to where you started, no?

I didn't say it was going to work...

I think they should mount them the other way around to see if that works.

the camber tire seems like it would always want to turn in toward the center of the car. the inside of tire would wanna go slower and thus wear faster than the outside. am i missing something, or is it self destructive by design?

sorry

autojalopsniff blog.

Cal Poly did that at FH last year:

Although, for what it's worth, our "conventional" car was much faster.

Sorry, didn't catch that. I knew you were smarter than that!

Hahahahahaha that E36 M3 cracks me up

Isn't that almost exactly what the old BFG R1s were? How did this guy manage to get a patent?

What, didn't you even look at the pictures? It makes perfect sense.

Regular tires = wagon

"Cambertires" = JET FIGHTER!

Many moons ago a company made recaps for circle track racing that were thick and shaved to hjave some camber in them for tracks you couldn't get enough camber into the chassis. It didn't really work well then either.
