So I'm replacing the front and rear wheel bearings. Ordered a set and began at the rear. Seems the bearings I got for a base 996 / Boxster are too small. The OD of the ones I got are just under 3" and the ones in my car are approx. 3.25"

I think the rear suspension is from a 4s because they use a different bearing but I have not been able to find true physical (size) numbers on these. I did find the Boxster at maybe 2.95" but no 4s. Anyone know the specs ?
