These half splotters are not your standard cheap Alumilite sign construction.  These are solid and straight in everyway.  These are Chasis and Frame mounted so that your front end does not rip off at high speeds or crack apart like others.  Unlike others on the market these use top quality materials and hardware for a long lasting, great looking, functional product.  Dont accept a cheap imitation. 
 
HIGH SPEEDS TESTED Most companies list on their sites that their splitters are not built for high speed but here at DFS we ask for it ... track tested and speed rated
