Just to add, conclude.
The newer machined pulleys are MILES better than the old moulded ones, particularly the centre drive pulley which is MILES MILES better than the moulded one.
The xx4 ones fit (though 2 rear ones needed) but change the ratio so you'll need to be likely a couple of pinions lower than on kit size.
If you were sold the kit on the premise that it was the current spec X5 squared, I'd ask them to change the pulleys for you, especially if yours have flashing on the teeth.
