Better option for front wheels

[Auradrummer]

Hello guys,

I'm still playing with Newton, with some good results. Now, I'll start to implement a car (more reallistic). I want to know what is the best option to make the front wheels steer:

1. Create a joint suspension->wheel:
That requires some calculus to determine the vector of wheel, as the joint have two degrees of movement

2. Create a joint suspension->brakedisk->wheel:
That uses joint with one angle of freedom, but uses two joints.

What option will give me more performance?
