Jpit, this car has big brake package and 15 in. wheels, no clearance issues. The rear of the car is lowered as far as the spring stops will go, the front is lowered to approx. 3/4 of spring stop adjustment travel. The backspacing on the rear wheels was increased by a local machine shop. I added 10mm spacers to the front wheels to fill out the fenders more. Rear tires just barely rub the inner wheel well on the harshest of bumps. 295/50 rear, 245/60 front. If you go the 15 in wheel route, I would suggest having the backspacing custom machined to your specs, there is plenty of meat on the Trigo wheels for this.
I have no flex in the dash when turning the wheel. There is a brace that runs from the steering column bracket to the firewall, I would check the integrity of that.
