I couldn't fit type s rims only on rear passenger side because of "wtf is this"

[int5]

guys and girls,
I need help

type s rims. 17x7 5x114.3 +45 offset
they will fit my dc5 base model without any problems but only on the rear passenger rotor i came across this [see pic 1], obviously it is too large to fit the wheel.

what is this purple thingie? and rotor cap? I think it can be removed but no so sure. Can someone please confirm and point me in the right direction Thanks in advance

rear driver rotor looks like this, with cap? [pic2] and it fits perfectly (without the purple thingie)

front passenger and driver rotors have no cap (?) at all [pic3, 4]
is that normal?

Thats a hub ring, it centres whatever rims you had before to the hub of the vehicle. Just pry it off and fit the type s rims.

Tap it with a rubber mallet all round and it should come off with ease.
