Not sure about hype, but Bilsteins have valved their shocks/struts as direct replacements specifically for the ST. The other performance option is Koni, but the oranges which a lot of people have put mainly for comfort at a loss of handling performance were specific valved for the regular Fiestas, not the ST. I don't have time for find the posts, but the front Koni yellows were never made specifically for the ST, only the rears were. Koni’s application guide may still reflect that. There was also mention of missing an OE like mount for the front brake line but Koni didn’t want to retool a strut housing specifically for the FiST. There was a guy back in '14 on another forum who help do some R&D with fitting and testing Koni yellows. So one set is not made for the ST and one is incomplete, when Bilsteins have made complete sets specifically for the FiST with options of B4, B6 and B8.
