It was required to bring the Manthey stuff into the catalog. PAG was reluctant to improve anything for years on cars unless cosmetics and not for all cosmetic parts…
 

looking also how the new coming RS was also developed in closed relationship, these parts are a good addition into the catalog. Manthey is not Techart, it is rather a step up for Porsche to be honest - not a cheap one though but every second saved has an exponential cost.
