Cayman / 987 wheels have the wrong offsets for a 986. Got to make sure you have the proper offset or you'll make an expensive mistake. The factory wheel size and offsets for 18" 986 wheels are:
Front 18x7.5 50mm
Rear 18x9 52mm
If you go 18x10 rear, the offset should be 47mm.
987 factory numbers:
Front 18x8 57mm
Rear 18x9 43mm
You could use a 7mm spacer on the front, but the 987 rears just won't work.
