STR5 throughout 2010 season raced three different exhaust outlets configurations .which are the following
Periscope , blowing between the suspension wishbones
( launch , Australia , China)
Periscope surrounded by bodywork , to improve car’s cooling
( Bahrain , Malaysia , Spain to Belgium )
Close to floor ( Exhaust Blown Diffuser ) to blow and energize diffuser boosting downforce production
( Italy to Abu Dhabi )
STR5 floor splitter has side vertical fences to better divide airflow inside and outside the bargeboard zone offering a smoother and cleaner airflow around the sidepod bottoms . The quality of airflow was improved further after the addition of the under nose cone fences since Hungary .
To prevent flow interaction between airstream coming above and below the floor , STR5 floor features side fences . Any flow interaction would create extra drag and would effect negatively car body downforce production .
STR5 mirrors are mounted on the cockpit sides and so the team need not to revise them due to FIA outboard mirrors ban rule taking effect since Spanish GP.
