TRZ control arms

hey fellas.
i just bought TRZ control rear upper arms which is double adjustable(which i will never adjust).do you guys know this brand? are they any good? i heard they use these at saleen. so i bought them . i went to maximum motorsports site and they only had 1 kind of rear upper control arm and they look so much a like ford racings. so i went ahead and bought this one instead. did i make a good investment? or is it another mistake part that i over paid???
