Alignment Specs

[firebob]

I'm looking for opinions on what specs I should set my caster/camber/toe to when I get the front end all put back together. My 69 Firebird is 90% street/10% track car. Real heavy in full street trim. Probably 3700lbs. I put on about 5K miles a year. I don't want to run the track settings on the street and wear the inside of the tires out. I run Firehawk 235/60/14 street and 27.5/9/15 Eagle Sports Car Specials at the track.

The new UCAs are said to have 5* caster built in to them. Sounds like 6* is about the limit of what is needed.

I heard people running 0*to neg 2.5* camber. It seems to me I read back in the day that 3/4-1* neg is what I should shoot for.

I suppose factory toe specs are fine for all around use.

Maybe I should get one of those adjustment gauges so I could run 1/2* neg camber/6* caster and slight toe out on the street and shim it up to neg 2* on track days. I wouldn't think adding the same shims front and back would change the caster setting, only the camber, right?

Any suggestions on settings for either or both would be appreciated.

I think you're right, if you are going to drive a lot more on the street vs. track, then you need 2 settings...and you might as well keep the toe and camber settings relatively mild for the street. But you need to really crank up the camber for the track, otherwise you'll wear the outsides of the tires more in 1 weekend on track than you will in 2000 miles on the street! I drive around on the street with -1.75 camber and +5.5 caster and 0 toe. Camber is excessive, but I don't feel like re-aligning my car for the street just to baby the tires, only to get out on track and give 'em hell anyways.

But I do recommend doing and checking the alignments yourself. It goes with the territory of tracking your car.
