Yeah but those others 2WD (YZ2, B5M Low Rider) are rather high grip cars

It rather looks like "the other layout" high and medium grip car than a true low grip car like a X-6, a B5M, a BMax 2 or even a SV2. Even the LG layout of current KF2s seems to have more rear weight bias.
Of course all of my gibber is armchair engineer ranting and will self-destruct if the next KF2 proves to be a low grip champ
