BC racing coilovers, not too low please

For your turn-in dilemma, put the CSL front sway bar. I have it, + the CSL alignment settings and the car is very eager to turn it.

CSL geo already applied. Thicker front bar makes sense to me in theory, as I only require added stiffness in cornering and not in a straight line. Will look into it - thanks.

I thought that a thicker ARB on the front would worsen understeer?

My old Z4 had adjustable ARB's and I experimented with many different settings. If I stiffened up the rear turn in was better, if I stiffened the front it made things worse.

Correct, all things being equal stiffening the arb will effectively remove grip from that axle, but in the case of the front it will reduce roll so will give the feeling of it being sharper to turn in.

Indeed correct, and any understeer issues can be dialled out with camber etc.

That's the fun thing about suspension tuning - there are many ways to achieve a similar effect, everything is interconnected meaning a change in one area always affects other areas, and the goal is to get all the variables working holistically to your liking.
