I would like to do this right, but it seems like there aren't very good options for those who want to lower their car but mostly maintain an OE ride. The SPLs are very well built but there is no denying that the spherical bearings will transmit more NVH and will require regular cleaning and lubing since they aren't sealed. The only reason I haven't just jumped on the SPCs is because I don't like those reports of the arms snapping.
SPC did recently release some new beefier arms though:
Specialty Products Company | SPC Alignment | The Automotive Alignment Leaders
They have a different design and are forged for increased strength and use a new bushing type that is supposed to perform like a monoball but have the durability of the OE part. They claim it doesn't require regular maintenance.
Specialty Products Company | SPC Alignment | The Automotive Alignment Leaders
Since it is so new, I can't find any reviews on it.
EDIT: I should also mention that SPC has revised the design on all rear camber arms for the Z/G to remove the curve. The arms are all straight now for increased strength. I guess this means that SPC's original design was deemed to have inadequate strength.
