Earlier this week we got to hang out with our buds from @grassroots_motorsports at @bmwperformancedrivingschools to play with some BMW M cars for an upcoming article. While there, with little coaxing we managed to get professional driving instructor and BMW wheelman extraordinaire Mike Renner to get behind the wheel of our BimmerWorld F82 M4 GTMore project car. He has piloted everything possible that wears a BMW roundel so his feedback and reactions after ripping around the test track was great to hear. The BimmerWorld GTMore truly does set the bar for F8X track cars. #bimmerworld #gtmore #grm #bmw #f8x #f80 #f82 #m4 #m4gt4 #OPTIMABatteries #teamredlineoils #pfcbrakes #motioncontrolsuspension #lifelineUSA #Alconbrakes #OMPRacing #SPLParts #MCS
