That's (negative) camber. Absolutely paramount for cornering harder, it also eats the inside of the tire's tread. (which can be somewhat correct with a bit more toe-in, which eats the outside).
It doesn't take much camber to be visible to the naked eye (my car is at 1.5° because I would have needed to remove and lengthen the upper control arm on one side to get the desired 1° on both sides, and I had to setup the alignment on 2 cars in 1/2 a day right before leaving for the rally). But it handled like a dream. I found my FWD Clio Sport dangerous (it felt like radical understeer at first) after I came by. Slight oversteer feels much better on the Challenger.
Now, if we only could add negative camber to the rear...
BTW, how did your French rallye go? Any pics, stories, ect,,(I love that stuff)!!
The rally went really good. We ended up at the 19th position in the overall regularity contest (out of roughly 75 cars at the beginning, 68 at the end). And without any tripmaster (all we had was the car's odometer and a chronometer). Not too bad for a first time.
Adn we had great fun on the little mountain roads and on the tracks. I still have some work on the car (I need a better cooling system, it's OK for everything except city driving, and I need a hydroboost brake booster), but I'm surprised I didn't have any serious problem (just had to shorten the fuel line just after the pump 3 times, ended up moving the pump, it was rubbing on the rear axle on compressions (that is, all the time with the way I was driving). The car drank gas (and oil, I'd say 7 quarts for the whole deal), but even the brake pads show no visible wear.
Oh, the rear shocks are toast. Pretty much the only casualty.
I have a load of pictures, but my personal web site seems to be unavailable (probably didn't use it for too long).
Even the resized, filtered pictures still account for 170Mo.
I need to find a way to put these online.
And I have video, too... although not too great (that was he first time I was using the Digital Hero 3 minicam), it's still pretty cool (only the sound is no good). One video is pretty damaged though, the front-bumper shot of the road after the Charade racetrack flickers badly. That's a shame, it was one of the 2 best mountain road climbing I did.
Here's a couple pics :
