JDM, Wheels SSR Integral S1 SSF – JDM Wheels December 25, 2016 admin Leave a comment The SSR Integral S1 are JDM Wheels that I probably have never seen stateside. Not as popular as its 5 spoke SSR Integral A2 brother, the SSR Integral S1 features a one piece mesh design with covered lug nuts. The SSR Integral S1 also features the SSF Semi Solid Forging process like its older SSR Type X brother. Pictured is the SSR Integral S1 mounted on a S14 Nissan Silvia and an R34 Nissan Skyline.
