I am not a big fan of the sizing.
My recommended sizing would be 265/35-18 and 295/35-18 rears. or even 275/35-18 for the front.
here is the set up on TK Square's Track M5.
I think they run those sizes because they are using AD08s.
295/30/19s seem to rub, so I guess these might not, but the overall diameter might be a touch small.
