number of things you could try, for your understeer I wud suggest less rear downforce or more front downforce. This will make the front grip better and it might make the car slide a bit. Another thing I like is negative front toe, I usually dont go higher then -0.12, and rear toe I would try at 0.00. If the car has to much oversteer or if you want to reduce it try a +0.6 to +0.10. Suspension wise I would aim for stiff springs. Most cars I start tuning I try to make the rear a little more stiffer. I would lower the ride height to about 2 points from the minimum. But Do these one at a time to notice cars behavoir. If the RH lower in front better turn in, lower rear will create oversteer, try them evenly and work from there. camber I would go with a 1.0 for front and 0.4 for rear. I usually try to stay below 2.0. Im not very good with dampers, usually I cant even tell the difference. For your tranny, depending on track, You want to be about redlining at the longest straight.
