You need to be aware that droped spindles could cause your tie rods to drop below your "scrub" line if you are useing 14" wheels with 2" droped spindles.
The scrub line is an imaginary line drawn from left rear to right front and right rear to left front bottoms of your wheels.
You don't want steering components to fall below this line for obvious safety reasons.
Also, depending on the type/make of wheel, useing an 11" disc brake will be a tight fit and may require some trimming.
Of course if you go with 15" wheels all should work fine.
