Just purchased RaceRoom RR2000 chassis. The chassis comes with rubber feet, (6) #751 20 117 and (2) #751 20 119. Does anyone know if these rubber feet will successfully act as 'isolation feet' for tactile transducers (using 4 ButtKicker mini LFE transducers in chassis mode with SimVibe software)? Or, do I need to replace the stock rubber feet with actual isolation feet made for tactile transducers (see image below of Buttkicker Kinetic Isolator RDB-375)? I want to get the most kinetic/vibration transferred to the RR2000 chassis.
