? about setting rear toe on 76 coupe
I think I know the answer but when setting the rear toe the 1/8" is divided between both rear tires so it would be 1/16" per wheel when shimming trailing arms. Correct?
Thanks

I didn't know that the rear tires received any toe adjustment, other than to be dead-straight. They are 'followers' to the front tires. The front tires need to have some amount of toe IN to prevent the car from wandering, or hunting.

Thanks for the answer but all of the specs I can find all say 1/8" toe in on rear end so that was how I was going to set up my trailing arms after just replacing the t-arm bushings.

Rear toe-in on a C3 is extremely important as due to the rear suspension design it will toe out on bump. 1/8" toe-in is absolute minimum (and yes, it is total for both sides or 1/16" per side). For track use vintage racers will set it at 1/4" or more to avoid toe out on corner exit (toe-out makes it unstable and can result in a spin out).

Is an alignment shop doing the work, or are you DIY the alignment ?.

I have always learned best by doing the work but this is new to me. It still seams the harder i work the luckier i get.
Thanks for the help

Sorry, I didn't mean to imply you should set it any higher than 1/8" (re-reading my post it does sound like I do). Higher toe settings are for race use only.

I will be taking the car to a shop to check my work and correct my mistakes if needed but I thought I would give it a try and see how close I come to getting this right. It's about 10 miles from the house to the alignment shop and I don't want to abuse the tires or risk a wreck with bad handling on my way there

eg. here is my example to measure thrust and total toe.
Total toe

When you measure rear thrust angle is that making sure toe on both sides is equal in relation to longitudinal axis of the car? In other words both rear wheels have the same toe in and not just total toe so the car isn't dog tracking? Thanks.
