I have been having some issues with the FFB and start up calibration of my T300RS recently. On start up the wheel would not spin to the left first but would only spin violently to the right and continue to do so. The only fix I found was to manually turn the wheel to the left so it would calibrate correctly so I could use it. The FFB seemed to be getting weaker with each race and I didn't want the down time of sending off the wheel to be fixed or replaced so I found this download that fixed it right up. You need to update the firmware first to make sure you are running the newest update http://ts.thrustmaster.com/download/pub/webupdate/T500RS/T300RS_Firmware_Update_Procedure_V25.pdf Then download the Zip file with instruction PDF for installation http://projectcars.club/wp-content/uploads/tools/T300-Calibration.zip After running both of these it fixed the start up calibration and the FFB returned to full strength. So if you are having issues with your T300 then try this first before sending the wheel back.
