Well i know that but in rules is no posting mods and tweaks etc.
and i don't think is good if on official website there are mods/tweaks
but thank you for explaining me this eroor

nothing wrong with tweaking a set. But, because R4 is selected it's probably a rubbish setup for normal usage. You can downvote though.

what he is saying is that r4s are selected yet you cannot select R4's for the xfg as your only choice is knobbly's / hybrid / Road normal
