This part have issue LOI on May'23 After that designer issue ECI no. H43HP0070 on Dec'23 about change spec material because HMA has designed the new front spoiler parts to improve the appearance of the new model and then designer got the rusty reports from HML to re-consider the standard of surface treatment to prevent the rust from occurring with new model parts. So designer have to change material from SPH to SCGA for prevent the rust.
