Don't have a rim or rotors yet, trying to figure out path of least resistance.
done a 996 swinger so 999 front would look odd
Aren't 996 fronts 6 bolt
and 999 are 5 i believe
Yes they have different mounting.
But the offset of the rotors is also different.
It won't be a simple conversion and it will be tough to decide without pieces to measure from.
