This is my setup, and much like Marcin's its a modified GH Zand setup. However I get a lot of understeer and I lose quite a bit of time in the second sector, around 3 or 4 tenths and maybe a tenth in the first.
After a few laps today on prequally server I managed a 32.750 which was smooth but definately on the safe side instead of pushing. Maybe if I get some more practice I will get it down another few tenths.
