recently purchased an 09 rs se5 super low miles and have been adding hand brake and floor boards. looking to purchase some risers and im leaning towards the rivca 3 inch even tho they cost a bit more, does anyone know if they will work with the isci hand brake? called custom dynamics about their 4.5 inch risers and was informed they arnt making them anymore but i have seen them else where. any thought or suggestions?
