I will be buying some reasonably priced LCAs and WL is my main option, due to weight factor

I've had both WL and SPC and they both have "SPC" stamped on them so they are indeed the same. This is also the case for the SuperPro arms.
Only difference will be the inner bushings, which will be polyurethane in the case of WL and SP, but SPC uses a "cross-axis" bushing that seems to be similar to the pillow bushing found in the OEM STi RLCAs. Weight difference between the bushing styles will be negligible. I believe that Whiteline originally had an offset in their inner bushings but their newest design has removed that.
Either way, all these "SPC" arms seem to be non-OEM replacement arms that are slotted by SPC. I believe some of these companies have procured and painted them for re-sale.
