E-Speed rear camber blocks - up or down ?

[nickhudson]

Having purchased some of the e-speed rear camber blocks, please could someone explain what the differences in handling are between mounting them up or down ?

I've seen setup sheets with them in both positions.

Also, is it important to use the rayspeed rear hubs as when you use the standard B4 (or B44 hubs as i have) the camber link is angled backwards quite a lot.

Thanks
