🙌 Agree! This will be the ideal upgrade for spring time! Stay tuned! 😉

Hi Matthew! Thanks a lot for your comment and for sure I will take this into consideration for the next one! 😉

Good suggestion! Thanks!

Hi was geht! Thanks for your question! What I meant to say is that the Rieger diffuser will provide a more aggressive look to the rear end of this car but I doubt it will be of any aerodynamic advantage (I haven’t tested it) as there is a noticeable gap between the rear muffler and the diffuser that can create air-pressure at high speeds. The aim of a rear diffuser is to help escape the air beneath your car, improving the overall downforce (the car sticks to the ground). A rear diffuser usually ends towards the middle of the vehicle and is used in combination with a front splitter/diffuser. The flatter the vehicle’s bottom, the more aerodynamic advantage you will gain. This advantage is noticeable at high speeds, not on a daily drive. Also, lowering the car might help (shorter air-gap between the car and the road, more air-pressure/speed is generated). A few years ago, I helped developing a front/rear diffuser kit for a Caterham (UK MSVR Championship) and that thing was simple and huge! We made it adjustable, so it could be tuned depending on the track. Check out this video (kzfaq.info/get/bejne/eNh3nad_vZ7IgHU.html) from XF Motorsports in which a diffuser kit is developed for an Audi RS3. Hope this helps!

Hi Giroud. Unfortunately, I have been busy with the next video. I haven't had the time to keep digging in OBDEleven. Next video about the CUPRA soon =)
