Currently on 500/600 springs, 22mm Perrin front bar on full soft and Mann Engineering 13mm rear on full stiff. After doing a bit of thinking I'm going to 450lb springs up front and a Karcepts rear bar.
Karcepts doesn't list that he sells a rear bar yet, but he sent me this:

I'd bump to the OEM or GR rear bar before dropping front spring rate. Going lower in front only increases the risk of blowing through the travel and spending too much time on the stops. The same problem you had with your out of the box set up. That would actually increase understeer. Unless you are too low in front or not running enough camber, you should have plenty of front grip with your current set up. You above 130mm front and at least -5°?
Regarding sensitivity to set up, you are right in that higher spring rates, all else equal, make the set up more sensitive. Higher rates also make the car more sensitive to driver inputs. So smoother, slower inputs are required to extract the extra speed potential. Sway bars are springs too so adding more bar has the same downsides of more spring; additional sensitivity to set up and driver input. Agreed though, when we wen to 616/616 (11kg) rates on Blub, it was definitely a tad harder to drive than 500/500, but also quicker.
Let us know what ends up working for you.
