The GLS ones offer minimal camber adjustment, also the bearings are a press in affair.
However if people want to organise a group buy, I'm happy to get prices and apply our trade discount with them for CG40 members.
Between Hayesey, Andy & myself, we've now done enough 'mule miles' to be confident in the PPP design ala:

These do give enough camber adjustment, but are designed with our stage 3 in mind, you really need this as the camber dialed in with a tca also alters castor angle.
I can ask about dates for these to be made if people are bothered?
