Is there a way to look at the calipers and tell if they are for 26mm ( earliest TTs ) or 30mm ( from about 6/90 on)? Pretend I don't have the brake rotor they came off of. If they are for 26mm, would cross drilled/slotted rotors be more warp resistant? CZP has cross drilled/slotted 26mm but says they are for NA models ( also late 89 TTs? ).
