I've been doing my own alignments for decades using a Sears inclinometer and tape measure. I got all my cars dialed in years ago. It was tough crawling around on the floor nearly all day, but once dialed in I haven't touched them since. You can buy an inclinometer nowadays from Harbor Freight.

Just last weekend I helped a buddy with a '67 435 HP Corvette correct excessive front toe in. Fortunately he has a drive on lift that made the job easy.

I have all my cars set up for maximum negative camber and maximum positive caster, equal on both sides within the allowable range of adjustment. On my '88 190E 2.6 I was able to achieve negative 3/4 degree front camber and 10.5 positive caster, and I'm not getting any uneven tire wear across the tread.

The negative front camber improved turn in response with less understeer and the slightly greater caster improved on-center steering feel.

I got the dealer to check it out on his state-of-the-art four wheel alignment machine and they said they couldn't do any better! The rear camber and toe was near OE nominal, which was okay by me, and we didn't touch it.
