Hi Al,

The caster is out on the left side on my 2006 STI.

They are 4.53 right and 3.34 left. Book says 4.50 so left is out by 1.16 out.
The car has AST coil overs fitted.
Is there anything I can check or what options have I got to get them the same?

 

I would start by checking your bushes specificly lower arm bushes and possibly play in the bottom ball joint

Are the bottom bushes prone for wearing?

 

not overly, but as you are running coilovers, its very possible, in my mind im thinking the rear bush, could possibly be worn! which Anti-lift kit is a good replacment

regards
Rob

 

Yeah I was thinking the same. If worse came to worse, adjustable top mount?

 

yup could do that, but if your problems elsewhere your just putting of a disaster, could even be your top mount bearing!
I would get the wheel off. undo the coilover lower bolts taking note of the the camber bolt position and also remove arb link and have a pull and prod around at everything

 

Yeah will do that this weekend. Did it on the drivers side as the strut failed after 3 weeks lol.
Going to measure the distance between front and rear wheels on drivers side, check same on left, remove strut etc on left, check bushes, mounting points, top bearing etc, then refit and re-measure.

 

sounds like a good plan, let me know how you get on

Will do, will do it Saturday and let you know if I find anything.
