If only toe can be adjusted, then it should be fairly easy to get that right without laser equipment. Maybe there is a difficulty getting the front wheels aligned with the rear wheel also that I'm missing. In my late 20s and 30s, I designed, built and raced tube frame formula cars. The suspensions were fully adjustable, front and rear, for caster, camber, toe, dive, squat, swing arm radius, bump steer, roll resistance, etc. We used string and protractor levels to accurately set all of these variables. I'm sure that I could perform the same on the spider using similar techniques. But if the computer has to be reset with a special tool after the alignment...all would be for naught. I need to learn a lot more about how the computer interfaces with the suspension on the Spyder. Where do I read up on that? I should add that it would take 2 or 3 of us HOURS to check and setup everything ( on our cars) using that method. Change one thing and it would require adjusting many other things.
I have a 2010 RT and Can-Am adjusted mine at the factory.... rear and front wheels where set going in the same direction. At the time mine were done, they didn't use a laser system. They set the on-board computer to thinking that my RT was now going forward properly with the wheels all aligned. Problem was, the way they did the alignment was not correct. Having seen the laser alignment in action, I couild probably get my front wheels pionted ahead OK with strings and such after properly aligning the handlebars... problem with that would be that i could not reset the on-board computer so it re-oriented itself to the correct direction of travel. If the original on-board computer setting stays in the computer, the vehicle will still pull to one side or the other. The BUDS interface and software is critical to any alignment and I think doing an alignment without the laser set up would be very time consuming and frustrating (if it couild be done that way). The alignment I got from Cliff Fargason was the single most improvement in handling I have experienced and was a lot less expensive than the Elka shocks, new Elka springs and Bajaron anit-sway bar and metal Heim links.
