I'd imagine if you fit the race haldex controller and fit thicker ARBS you can dial out the understeer
Hmmm I'd be surprised to be honest. You might change the natural balance by essentially making the rear suspension worse than the front, but I can't see how you'd ever stop it understeering under power. The sad fact is it's front-wheel-drive with the ability to connect up the rear axle (to varying degree) when it's told to. All the aftermarket Haldex controllers do is give you more options for when and how much the rear axle is connected to the front. You can only spin/break loose the rear axle with power if that's already happened on the front axle - in fact it's mechanically impossible to rotate the rear axle faster than the front axle under power. At least other performance cars with mechanically very similar 4WD systems - Porsches, Lambos, Veyron, A8, Skyline, GTR etc - have the decency to put it the right way round!
So glad you've seen sense! Have you tried out a Porsche yet? Or thinking you could handle the few extra inches width of the Vette?
