@Slickric21 I have to agree with @Jaco2k on this one, I have the Rieger front splitter and rear diffuser fitted on my 2017 St300. I have to say that the Rieger gear fits like a glove and looks awesome on the car. The front splitter was easy to install but the rear diffuser was a pain in the a**. I know there are a few options to choose from but my money would be on a Rieger all day long. By the way no whistling noise at speed. Had front splitter for 9 months with no problems, rear diffuser for 2 months. View attachment 5102 View attachment 5103 View attachment 5104 View attachment 5105 View attachment 5106
Totally agree that the Rieger Splitter is the one and both @Deano j1971 and @Jaco2k and myself found the front splitter a piece of cake to fit. Looks OEM too.
