Here's a pretty informative video - a wheel cam (front left) on an Aussie V8 Supercar:

They are running 6-6.5 degrees of negative camber and it seems to be enough. Also makes me think my 3.5 neg is just fine. It's also interesting to see that they don't seem to have an issue with picking up the inside unloaded tire. Now I wish I could mount a camera under my car at the next event.

Also, why don't we have a cool racing series like this in the US?

 

Nice video. How much do these cars weigh and how much power do they have?

 

From Wikipedia:http://en.wikipedia.org/wiki/V8_Supercar

Power: A V8 supercar is powered by either a 5.0 L Ford "Windsor" SVO or Chevrolet Aurora race engine (depending on the make) which produces 620-650+ bhp. Engines have pushrod actuated valves and electronic fuel injection. Both Ford and Holden engines are based on racing engines from their respective US parent companies. Engines are electronically restricted to 7,500 rpm.
Weight: The minimum category weight is 1,355 kg (not including driver) 80 kg driver allocation (about 3000lbs).

And from NASIOC:

Gee, I wonder where you saw that vid? No worries, I take the verbatim comment as a compliment.

 

Thanks for the information.

 

LOL! Funny thing is that I actually just cut and pasted that header and link from yet another local forum. Besides, I know you are both forums already Steve so I didn't intentionally steal your content . Even after all these years it still cool how this stuff/text gets around

Regardless, it is still a cool video and makes you think about what's really going on with your tires during a run.

 

The internet is an amazing thing.
