get a tape measure.
take your factory wheel off. on look on the rotor, there is a little lip in the middle. its the same side as the hole in the direct center of the wheel.
now here is where the tape measure comes into play.
Measure the diameter of this lip. it will be 72.xxx mm
now measure the new wheel u got. on the inside, it'll be 64.xxx mm.
You have hub centric wheels. this means that wheel was designed to fit onto that hub portion and carry some of the weight of the car.
The inside of the new wheels will need to be bored out to that 72.xxx mm (and some1 please correct me if i'm wrong on the extra measurement) to get proper fittament and for safety.
