In Tandem with these Front Wing changes the team also revised the nosecone of the RB8 utilising a 'Pelican' style underbelly to the nose whilst extending the tip of the nose and also placing the FOM Camera's into a more forward and lower position. Red Bull have adopted the hammerhead camera placement since Belgium tidying up the area between the Front Wing Pylons and allowed for the introduction of the Tilting or Rotating Wing and 'Pelican' underbelly. Like most teams Red Bull originally used the camera's in a position behind the central section of the Front Wing to attenuate the airflow's characteristics. This is important as the central portion of the Wing is an area subject to specific rulings set out by the FIA in order to the limit the amount of downforce/effect generated here however with a Lower Nose tip and 'Pelican' underbelly the effect has been altered higher up.
For Korea the team made revisions to their exhaust package and bodywork in order to further utilise their ramp and tunnel combo. Internally the team went back to an exhaust featuring a resonator chamber and visually it would appear that the size of the resonator chamber has been increased.
This is coupled by the shortening of the Exhaust ramp and re-profiling of the Cross-Under Channels. Sebastian trialled the new configuration on Friday along with Mark but switched to the usual lengthened style claiming the balance wasn't right. However both drivers ran the new configuration for qualifying and the race.
Lastly here is a 3D video created by Giorgio Piola for the AMuS website on some of the alterations I mention above:
