Anything worth running in Enkei’s racing line including the RPF1 is a hybrid called MAT, not simply cast.

. MAT Most Advanced Technology MAT is a new technology for producing an aluminum wheel, that is a combination of MAP and Flow-Forming forging technology. ENKEI applies MAT to High Performance aftermarket wheels and special Performance components of Original Equipment (OE) customers, such as 2003 Mitsubishi EVOVIII and 2004 Acura TL Limited.
