I had an alignment done in the spring, using supermiata dual duty alignment numbers. When the car came back,he gave me the numbers I wanted for toe and camber, but he said he could not get the numbers for caster. I am trying to find the sheet he gave me ,I am pretty sure caster was around 2.7 positive on both sides. I have taken the car to one track event, but the longer I have driven it, I don't like the way it drives. Too darty ,if that is a word, I have to concentrate the whole time I am driving it, to keep it centered. I believe this is because of the low caster number. And oh yeah the car is lowered to a 4.5 pinch weld height. Is this a common problem? Any fixes say you mighty minds?

Extended lower Ball Joints allow one to hit the Camber numbers, and also have lots of Caster. I don't know if 4.5 PW is low enough to not need them, or not. May depend upon NA vs NB?

I'm at 5.5 / 5.75, with the ELBJ, Dual Duty and 4.8* Caster. NB1 with power steering.

Forgot to say I have extended lower ball joints ,my alignment guy has like 30 years experience , lowered cars included. I have not replaced alignment bolts, car is an NA

When I lowered the car on these teins I measured from the fenders, was at 12.5 front, 13 rear. Now pinch weld is about 4.5 front and rear. I guess this is why Emilio says use pinch weld. Still does not explain lack of caster.

Look at the rear-most eccentric bolts on the front. If they are not turned fully outboard, then you have more caster available. This assumes that the front-most are not fully inboard.

Does that make sense? The front-most primarily control camber, the rear-most primarily control caster.

Find the sheet. 2.7* of caster should be a cakewalk to meet on stock hardware. If it's identical at 2.7 on both sides, get a new alignment guy. If one side is 2.7 and the other is very much not, check your car.

Update; had the car aligned again, same shop, and asked him to get as much caster as he could first, THEN get me the -2.5 degrees camber. (another website suggested this). He came back with positive 6 degrees caster,(so he said ) AND my -2.5 degrees camber. Regardless the car now drives as it should have ,steering is a little heavier,, but it stays centered on the road and is easier to drive. I now like driving it, much gooder! Thanks for your input and suggestions!

That's just double headed weird.
Why did he have trouble the first time?
Did he charge you second time around?
Strange...

He was looking at the eccentrics upside-down....

You can have a couple degrees of mine if you want.
