Ok i bought my car and it was a shell with the mounts for a b16 in it so i got the b16a1, but i need to replace the wheel bearing in my front hub. Im not sure wich model it is and if it even has stock brake rotors any more. I need the specs for the rotor size and if there is any way to tell what kind of car model i have. Thanks. by the way im pretty sure it is an hf.
