roughneck,
the B210's 20mm bar represents a 100% increase in rate over the standard B110 17mm bar (ie it's twice as stiff). It is a little wider, but should not be a problem even with the standard 1200 lower control arms. Just bear in mind that stiffening the front will change the car's balance more towards understeer (or less oversteer). depends on the rest of your suspension setup obviously.

dattodude,
you should be able to fit it with the CA. try turning the bar over. if that's not enough, you can space it away from the chassis with some alloy plates, as long as it is not too drastic it won't cause any problems.
