Home Alignment (Chassis Checker and Lasers)

[chrisp993]

Rushing to finish my build I performed a very rough alignment. But I had plans for using 360 degree lasers to replace the "string" in a traditional string alignment. I also came up with a very inexpensive chassis height checker. More details at Chassis Height Checker and Laser Alignment blog posts. Overall this seemed a success!

 

I'd be interested in feedback on the alignment method and whether anyone else has gone down this path?

Incredible timing. I was just thinking about this very idea yesterday. Setting it up square with the car is still the key, but not having those strings to deal with is mighty appealing...

Setting it up square was easier than I thought - once aligned left/right to have the laser "wall" be equal distance from each rear hub, the mount was pivoted around its vertical axis to get equal distance from each front hub. Since the mount on the rollbar is close to the rear axle and I started with the laser lines "eyeball square" to the car, only slight pivoting was needed (since small pivot at rear axle = significant distance at front axle) and it did not disturb the rear hub distance any measurable amount.

 

UPDATE: Testing, setting up the laser box, from scratch, took ~ 20 mins. I did realize that the laser line span where it's mounted to the bar is constant and so you can use an accurate measurement of that to check the box all the way forward and back. So once you have this measurement, getting the box "square" is fast, then just need to carefully nudge the bar left/right and rotate to make it align with the car.
