you can add 30 minutes of caster or camber, not subtract.. you can set it to standard setting which is "0" though

read the manual as I said!

it will make it better, but it won't make it perfectly matched on both sides by any means

perfectly matched on both sides would be good if our roads were perfectly level but they aren't they camber off which is why 1/2 a degree caster variance is often set during an alignment. care to post the relevant page of the manual stating that you can not decrease caster during an alignment Edwin.

why don't you click the link he posted a few posts up? it has a scan of that page

JDM323 · 11-08-2013, 10:49 AM

already done that which is why I was questioning your reply as my advice will Increase his caster on the left/passenger side not decrease it.

Sounds like worn lower control arm bushes then

Jez4 · 14-08-2013, 08:45 PM

they did the front and back

JDM323 · 14-08-2013, 09:32 PM

then check bushes as rupe said

Jez4 · 15-08-2013, 05:27 PM

Btw the bushes looks ok ., but my eyes could be wrong., what does it looks like when its worn out?

Easiest way to rectify your caster and have your left hand side have more caster is to replace the lower control arm rear bush with a superpro or nolathane product and it gets rid of the old tired bush at the same time.

Also the factory bush located in the lower control arm rear bush has a elongated crush tube. When the bolt is undone and having a decent lever bar forcing the lower control arm outwards and re tighten the bolt at the same time improves caster. And the tops in the correct direction

Ill have my mechanic check for that as i dont have apporiate tools atm so yh but thanks!

No worries.

Fairly simple for a mechanic to fit provided that they have a hydraulic press.

a product off the top of my head would be a superpro product SPF2573K
This is a single increase/decrease kit

You would install the non adjustable on the driver side and the adjustable on the passenger side to increase caster.
