Default What alignment Spec's are you using?

I'll be sending out a car this week for alignment and trying a new shop. What spec's have you set your cars to for street driving, stokc, VB&P, etc?

Thanks
Gary

I like the stock radial tire specs.

I'm using new but stock configuration suspension (thanks to VanSteel) with the exception of 550# front springs with 1/2 coil cut off to match the ride height of the rear with 8" bolts.

With the ride height at 27.5" all the way around, I am using the following alignment numbers:
  • Toe: 1/8"
  • Camber: 1/2* Neg
  • Caster: 3*

Most important thing of all is to make sure they're EVEN ON BOTH SIDES. VB&P suggests 2.75 caster, but if one side can't get that high, just make them both as high as you can and keep em equal.

I went with about -0.5* camber all the way around. I put a tad of toe out on the front, about 0.15" on the front and .05" in on the back. This made my '81 handle WAY better than before. I HATED the factory suggested alignment.

Will the specs that VB&P suggest work with stock suspension components or is it specific to their hardware? I'm ready to have my '69 4 wheel aligned and want to get the most out of it.
Thanks!

Their alignment data is for the stock setup, except they note that if you have the offset a-arms that you set your caster to 4.75* positive.

Which one of the settings are you guys using from the four that VB&P lists? I'm thinking I want to do Advanced Street, but I'm not sure. Will one cause more tire wear than the other? What is the difference?

If you're using 255-60-15s, you're going to be hard put to wear them out before 30,000 miles regardless. I've got like 13,000 miles on my tires and they only have 33% treadwear, even after doing autocross. I'm actually using a setting closer to a track baseline. I need to bring my front toe in a smidgen, though. You might notice your turning radius will be a bit tighter with a different alignment, too. That or my freshly rebuilt suspension made it tighter.

Everybody seems to be in general agreement.

Great sheet but one problem. Why doesn't it say which direction the toe is pointing? in or out

I don't remember ever seeing a street vehicle that was set up for toe-out...and I used to work on the database for Hunter's aligners. It's a recipie for darty handling at best. Even 0* toe often likes to wander.

Funny you mention that. My front tires are set to toe out. Doesn't seem to "darty" to me. However, I prefer it to respond quickly.

You've said that before...and I'm still having trouble imagining it. It should be wandering every which way. Basic physics - if the front of the tire is pushed out, everything you bump with the tire should be trying to push it further out.

Toe OUT is for FWD cars.

That's what I was thinking, however, I've still got more wear on the outside of my tires than the inside. Also, VB&P recommend 3/16" toe out for an autocross baseline. At high speeds it seems to have a more positive feel around bends and corners now, though.

Most FWD cars spec for toe in. I quickly flipped through one of my old spec books, the only cars I saw with an out spec were a couple of Acuras, a few Alfa Romeos, and a couple of Fiats.
