Man, I would not flair your car . It just looks so sweet! First, I would switch to 555r yoko Drag radials in the 245/45/17 size. This will still fit,give you a little more height/and be a bit stickier. Then I would turn the boost down to a more streetable 10 psi. Should hook better and motor will live longer. Also lower the spring rate on the rear so that the car squats a little more for better weight transfer. I think theses small changes will make a big difference.
