the understeer you are getting is it slow or high speed? is it happerning under power or on first turn in? mine suffered from understeer on the exit of slow corners under power and until i had some video of the car i could not work out why. under full power coming out of slow corners it was almost pulling wheelies and i have a lot less power than you, raising the rear helped this. In high speed corners i was getting turn in problems, some toe out on the rear helped a bit but putting the front spolier/splitter on cured most of it.
looking at your car it seems very low on the suspension although the ride hieght is not bad due to the wheel size. going up on ride hieght might help as it will let the suspension do its job, allowing more travel thus letting the tyre grip, when you go from a spring to solid [ethier on the bum,p stop or coil bind] the wheel rate goes through the roof and kills grip no matter what tyres you are running.
i see your running coil overs on the rear, is this with the torsion bars as well?
i would try and go up on the front anti roll bar, kercher do a 22mm one. once thats on get a 944 20mm rear bar, in fact get as many rear bars as you can get hold of and test test test. tyre temps will let know when your getting close and then it getting it right for your style of driving. if your just sticking it in to corners and planting the throttle i dont think any suspension set up is going to help as a light rear engined car with your sort of power is allways going to understeer.
dont take this the wrong way but take a look at how your driving the car, might be a case of tweeking your driving style to match the car rather than trying to set the car up to match your driving stlye.
Hhave fun.
