I have two brand new FAG replacement wheel bearings for all Boxster S. One is a rear (p/n 33 41 1 13 4 549) and one is a front (999 053 041 03) which is also the front and rear on a base Boxster.
Here is the ********************************AZ page where I bought them - about 31 / 35 bucks each not including shipping. I had them as spares but never ended up using them and now the car is leaving me

New in boxes and plastic wrapping, never removed. How about $25 plus shipping each?
