We welcomed our friend Graham back to StudioRSR this time in his new project. He came in for the world's first set of CKS Suspension lowering springs for the F90 M5. Graham was very pleased and impressed with the previous repairs, upgrades, and customizations with his F82 M4 at StudioRSR (Watch his car on the dyno here) and was more than ecstatic to get started on his F90 M5.
