Congrats to rmzmotorsportza and thatgreenrs3_ for going 8s all boost at 5500ft in their IMS1150R and Iroz tuned Syvecs powered Rs3. Those that have never raced at altitude will never understand how difficult it is! Can’t wait to see this thing at sea level on real track prep. #irozmotorsport #syvecs #audi #rs3 #daza #xonarotor #tialsport
