54141 = Crack quite easily, but on the plus side tend not to fail completely, so you finish the race! I've also never bent a hinge pin while running them (so far!)
54283 = Don't crack as often as 54141, but like the front 201 arm I have found they bend and twist, so need keeping an eye on as they knock the geometry out!

Rear
51279 = as per 51275
54142 = as per 54141
51449 = per 54283, except I haven't yet found a twisting problem with them. It's also worth noting this arm has a cut out that's required by the 201, which I don't always see on the other rear arm options, so I'd always go for 51449 for the 2wd!!

I agree with you , Dave, only both you and Jamie forgot about the standard DB01 arms which are 51311 for the front and 51313 for the Rear. Have exactly the same geometry and thickness like the 501 arms but are way softer, nevertheless they tend to bend the hinge pin too just like the 501 arms BUT they cost nearly half of the 501X arms that´s why i always use them on my 4WDs.
Dave, what cut out do the 51449 have for 2WD? Never realized that!
