Like a set of focus rs springs? I am pretty sure they are a completely different platform with no cross compatability. Im pretty sure the Fiesta WRC RS is just a concept and you cant get those parts. If youre getting springs off an old mk3 (i think) Fiesta RS, I HIGHLY doubt those would work and might be hella risky just due to old age. Id look to just source some h&r drop springs, guaranteed compatibility and reliability.
