Toyota have visibly learned a lot from Renault's R27, especially in the sidepod area. Similar to the R27, the mirrors are now also attached to the sidepod shields, albeit a little more detached from the air-guiding panel (1). In fact they have also taken measures not to be warned by the FIA for too vibrant mirrors. While Renault had to add a small strut, the TF108 has its sidepod panel attached with two firm carbon fibre connections (2). Additionally, the rear wheel flipup has extended more to the front of the sidepod (3), almost as long as was the case with the R27.
