Aside from all the roll center talk, I do hope you aren't running on the stock tires. I'm at about 2" drop, which is equivalent to ~50mm, and until I finally got a chance to wrap my RPF1's with rubber, I was miserable. It was like driving on an iced over lake. Front push, then sudden snap oversteer. Got some new rubber and all was fixed after some dampening tuning to compensate for the stickier rubber.

Not that your roll center isn't off, it's great that you are taking steps to correct this, but some things are often overlooked. You might have already upgraded the rubber, in which case, ignore my comment, heh.

Edit: I forgot to mention, I attribute this to the stiffer spring rates asking the hard stockers to handle a level of grip that far exceeds their ability.
