for drifting on a car with power we will use +0.5 degrees of camber so that when you are on the gas you have perfect ture wear, lots of smoke and forward traction.
the only guys who need oni camber is the VIP style dudes, and while our arm was designed to be longer because thats what a drift car needs, you can take out all of the nuts and just use the built in clamps to secure your maximum negitive camber adjustement. I dont know what that numer is because we have never tried oni camber on our arms, worst case scenario you can cut the arm legth and reweld it shorter which is common in demon camber cars.
I dont know that its popular enough to justift a mass produced super short arm.
I took out all the nuts and got as much negative camber out of the orange arms you provided. It was some but not enough to fit the wheel properly. see car in signature.
