Go the Lightforce XGT 240's!!:D
No airflow issues with me, (TD5) the 1st pic is Mundi Mundi Plains out the back of Silverton, Near Broken Hill in Jan last yr, 48 C that day!! the car was running while we stopped to keep a/c on & we spent at least 3-4 hrs in the area with no issues of overheating or airflow issues. Had them on my D1 as well with ARB bar with no issues either.(was a V8)
