thanks, i am looking for the factory specs, thks bob


Jimvette999, thanks i will print those out and will review next to the factory specs, thks bob



and heres the rest of the story..... i took the vette this am to get an alignment done since i recently put on the steeroids. .... i say to the guy that the shop that did the rear end alignment bragged to me about it being perfect.....today this guy said "good i hope so cause this machine is incredibly accurate"....you know where this going..... the front end after my quick and dirty alignment with a measuring tape and a two boards was pretty close on the toe in....however the rear end was not even in the ball park of being correct it was so far off it was embarassing.....i hate relying on other people to work on my car i am seldom satisfied with their efforts.....

What does 1/32 toe in mean? To me, toe in should be measured in degrees. Please explain.

bobs77vet

no expert here but the fraction just gets converted to degrees

so from the factory shop manual for toe in it is given in two forms:
+1/4" +/- 1/16" equals +0.25* +/- 0.06*

Even though toe-in is an angle, it is measured using inches (or at least it use to be before computer alignments). 1/32" means the difference between the front and back of the tires. You just need to pic a reference point on the front and back of the tire (i.e. one of the treads) and measure across the car on both sides of the tire. "Toe-in" means the front of the tires should be closer than the back.

anybody? how about the specification range off of your computerized alignment print out? thks bob

1977-1978
Front:
Caster: 2.15 deg. +- .5 deg.
Camber 0.75 deg. +- .5 deg.
Toe .5 deg. +- .13 deg.
Toe .25" +- .06"

Rear:
Camber: -.88 deg. +- .25 deg.
Toe: .13 deg. +- .06 deg.
Toe: .06" +- .03"

These are from my Hunter spec book, but we would only use alignment specs from the factory in the books.

Sorry for the delay....it's been a crazy week.

thanks Batman..let me go check what they set it up to..... we had crappy weather the day it was aligned and then snow etc..etc so i never got to see how it felt...I had the chance to run it out on the highway today,had it up to highway sppeds on the interstate and it was rock solid i even looked for grooves and they didn't phase it at all, i even went to the worst rutted road the one that use to make me feel like i was in a bobsled and it didn't have any problem! got home checked the tire pressure and they where at 38 psi...i guess from the alignment shop....can't wait to retry at the lower tire pressure i suspect it will feel even better...the steeroids is incredible....thks bob

bobs77vet

My settings are on the right..thks i wanted independent verification on what they did and i feel alot better now with both the road test and the specs...thks again bob
