Based on what your currently running this link will help show the differences

The LM's you have linked, the fronts will fit, but the rears would not from an offset perspective. - Would stick out 30mm more than your current wheels.
From a max width perspective 8.5 front & 11 rear will work, its usually the tyre that causes the rubbing.
If you go 8.5 you will need a 235 which works, and 11 would take a 295 which again works.
If you happy with what you current run look for 8 & 10, personally I feel anymore and your carrying unnecessary weight. - An 8 will take a 245 and a 10 will take a 295 which is more than enough tyre for a 996.
Offsets are the challenge, you need to get as close to what you current have, so circa ET50 front and ET 65 rear, A little either way is no big deal.
BBS E88 are as good as it gets, LM's are cheaper and look similar, E28 are best avoided as they have a habit of cracking.
Higher offsets can be reduced by the use of spacers, lower offsets can not be increased.
