What leafs do you guys use?

yah. i don't know alot, but I don't think the wheel should be sitting further forward on the driverside.

The Passenger side is supposed to sit higher though. thats how they were new from the factory also. It helps alot with traction. they're called bias springs.
There is alot of engineering and stuff that goes into why those work like that. and i'm not sure exactly why, but they are definitely supposed to provide better traction.

The passenger side is set up like that for power transfer. Most power is applied to the passenger side, therefore the stiffer spring to plant the power. Similar concept to a traction bar, I know how they work just didn't think they would ever do that to a car from the factory.
