The GTS does manage to look wild and striking, but for me the design of the M4 is so aggressive as it, why do more? Maybe people complained that the previous M3 GTS was too ordinary. That said I do feel it is too kitsch and overdone and looks like something you would see in Fast and Furious.
They should have used a CSL approach and ditched the Rotiform looking rims, which look like something fit for a Gti instead of a R2.5mill BMW. Even the wing, surely BMW has more engineering ingenuity to simply slap on a Jap-style fin. Even an Audi TT and A7 have electronically speed adjustable wings. So BMW solutions on the GTS are just very crude.
