Yes- by choosing wheels that have compensating backspace for the extra 
1/4"-5/16" from those outside mounted brake discs. Of course, then the front 
scrub radius can become significant and steering effort & tire wear goes up.... 
Be sure to carefully check both sides as many Panteras are asymmetric. What 
is ideal on the left side might stick out 1/2" on the right side. Some 
aftermarket aluminum wheels have thick enough mounting flanges that a bit can be 
machined off the backsides of the flange without seriously weakening them, 
but others do not. You may simply have manuvered into a corner where you 
CANNOT maximize front tire widths beyond about 245-50 x any wheel diameter. 
Good luck- J DeRyke
