I'm having a hard time mounting the laser heads. How do you make sure that the two heads are 100% straight and parallel with the road? I tried make a few measurements but everything is curved on the bumper so I tried to 'eyeball it' and when I step back I think they are skewed outward a bit.
How do you make the reference to ensure they are straight and parallel?
The car is a BMW M Roadster (like a Z3) so, the bumper is curved
I have the level for the level piece, no issues there. Also finished wiring in cabin, radio mute, and custom on/off / LED switch.
Thanks! this step is killing me!
