$30 well spent. Went to HF and bought this to align my wife's car.

This should help when doing alignments. String drives me crazy. I will mount it to my camber tool. Where it really shines is going to be able to mark the car's centerline. I just placed it under the car, but you get the idea.
Even just mounting it to the bottoms of the rims, toe is off somewhere. The camera was in low light, so it's long exposure caused double lines, but this thing is going to rock. The driver side toes in towards the front wheel, the passenger side clears. Once I mark a center line and get the tolerances, I can figure out what is what.
