The revised rear shock tower is 3.5 mm thick and not 4 mm as mentioned earlier. The old one has a thickness of 2.5 mm. Same part number as the old one but the difference is that it has new cut outs.



The bottom rear shock tower in the picture is the newer revision.



Putting them one on top of the other, I also noticed that the rear body post mounts are slightly lower than the old one.
