Random update - so I spoke to the tech at the dealership while getting the car serviced/alignment done and he said that as long as the RSB angle remains unchanged there should be no difference in ride height. I'd be curoius to know whether anyone has experimented with those "adjustable" RSBs (different linking points) and noticed any observable ride height difference when using different linking points...
Regardless, I'll update when/if I finally get Tanabe RSB (been on order for a month, supposedly wil be here early Sept) although at this point it looks like it will have no effect on ride height.

 

Ok, after sitting on a swaybar for couple of months, I finally installed it last weekend. As many of you indicated, there was no difference in ride height whatsoever, so this theory can be put to rest.
On a separate note, the actual swaybar is pretty good, stiff as hell and a bit bouncy (particularly in a leteral fashion) but the car feels great in corners.

 

what about impul springs, are u happy with them? how do they compare to the stock springs?
