Most DIY methods and tools are only toe setters, which can allow the car to crab because the entire car was not squared in strings. the biggest error in doing a string alignment is assuming both your front and rear track is the same, it is not, the Spridgets have a wider front track, different wheels, spacers of course can change all this, so if front and rear track are not measured, all this will be in void. The easiest way to measure track is measure from where the tire makes contact with the ground on the outside of one axle to the inside of where the tire makes contact on the side of the same axle, this mean to be squared in the strings the hub center will be further away from the strings in the rear than than in the front, if correct it should be in the rear exactly a half of the track difference away for the string in the rear, this is big time important if this is not taken into account, then the strings will run at a angle and the measurements are useless. Aslo you need some sort of turn table for the front wheels so as you make adjustment and the wheel and tire can turn freely during those adjustments, now here a trick on a super cheap set of turn tables for home use, racer do this all the times, get 4 pieces of commercial tiles, use two for each front wheel put some wheel bearing grease and WD40 between the two tiles for each front wheel and tire, this will alow a friction free surface for adjustng the toe. The string alignment I have just described to you work exactly like a high dollar aligment machine using lasers and computers to do all this, exactly. Modern alignment machines are like X boxes with wrenchs these days, it allowed the tech to no longer engage his mind, the machine tells him everything he needs to know, while it doesn't make for smarter techs, it allows you to train a lesser than smart tech to do the job, if you are willing to think about this, fiquire out the method, the string aligment does the exact same thing, and you can do as good as a job as home as $100K machine can do.
Drew the only adjustment you have on your Bugeye is toe, all others have to be done with add on devices as for camber and castor. Hope this helps, call me if you need to.
