I tried this diffuser for my F103RM chassis and it is very lovely looking. Excelent and perfect aerodynamical improvements of your car. Alse it is a great guard of the spur gear from the dirty track or bad competitors who attack you from the back. Absolutely important and wonderfull part from quality lexan.
Woooosh, this diffuser looks great. A bit more downforce on the rear wheels and no more dust in my gearing (I run my F103 GT on an asphalt track) cracking spur gear teeth. My whole gearing can't die anymore, let's go racing
