i do everything by eye.
Wait til you get a setup kit on there, makes you realise how f'ed up your setup is when you do it by eye. Like I said though, it only matters for racing. I checked over the car of a guy who does it by eye, and it looked ok. When we got the setup kit on, we found he had nearly 5 degrees toe out on the front, one rear wheel one degree more toed in than the other, droop on every corner different, camber on every corner different. His car was transformed after we had finished, drove 20 times better.
