as said above vented looks like two discs together. drilled and grooved have very very little performance gains, they just slightly increase the light of the pads. if you have solid discs on there now, which is just like one plate, then for you to get vented, the one with to plates, you might be in need of some new wider calipers. im not sure but i think!!!!!!!
i bought vented discs and it didnt make abit of diffrence to the car just looked better than the plain and i didnt need to replace brake calipers and u dont need to but u do need diffrent more expensive brake pads else it will screech wen u brakei duno if i should get vented discs or just leave the ones i got on there
