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. cheers rob

Turn in was fantastic, trail braking into a corner planted the nose and she dove right in, but when the weight transferred back I'm pretty sure i was on the stops on the outside rear. I could just breathe on the throttle and she would plow coming out of high and low speed corners, but it was easier to see on the low speed. The ride height is actually too low, I knew that going in but I thought the springs had enough travel and poundage to cope, but that wasn't the case. The rear coilovers are the only rear spring, there's no torsion bars in this setup. I'll have to keep my eyes open for different rear bars. I want it to be slightly softer in the rear for grip and stability coming out of corners, so I'll probably try a few different rear bars like you said. I noticed the problem on my first run and had to drive around it the rest of the morning. I was anticipating problems though and didn't expect it to be perfect. The last few events this year are all test sessions to prepare for next years point race
