Ok the amount of camber required to tilt a car enough to make a big difference is so huge it'll never happen.

But lets assume they altered the ride height enough that it was a factor. The oil pickup is at the lowest point in the sump. Due to the design of a sump, that point will always be the lowest unless you have hugely different ride height.

Therefore baffling will work perfectly.

Dry sumps have their own advantages but none that would be necessary in banger racing. Also I would seriously doubt there is any suspension set up in banger racing.

Look at NASCAR. They race in an oval and dont use dry sumps!
