Momo the rotors do not look at all like factory. The Ven05 is normally a heavily vented rotor with ridges. The only aftermarket brand I’ve found that works well with Ven05 is Frixa, which would be a smooth, round rotor. Much like what you have there, although the size does not look correct. You may also have the wrong spindles as indicated.

Thanks again for the reply James. I didn’t post it to keep the post length down but those are brand new Frixa rotors and pads. That was the brake work I did along with rebuild on calipers and rotor floating pins.
I compared them to the stock CRG rotors and pads and they are the same physical diameter.
Came back out to the kart track and taking some measurements right now. Comparing to another crg they have here in storage.
