I came across a video today that mentioned that the RC350 has a beefier A Brace up front:


In looking at the diagrams, it looks like this brace is composed of part numbers:
51216-24030 - REINFORCEMENT, FRONT SUSPENSION CROSSMEMBER (~$145 from LexusPartsNow)
52255-24010 - BRACE, FRONT SUSPENSION MEMBER (~$190 from Amayama (shipping unknown))

It looks like there are GS350s that are also listed as compatible. Does anyone know which ones came with the updated brace and if it's worth looking at?
