Evo MK5 locks for Saab models. Thatcham approved wheel locks with rotating collar. Check the specification of the locking wheel bolt/nut matches that of what you have on your car. An aftermarket wheel can sometimes require a different specification of bolt/nut. Always check that you have the minimum 31mm hole diameter on your wheel to take the key.
For Saab (especially the 900), check the shaft diameter 12 or 14mm to confirm if you require M12x1.5 or M14x1.5 bolts.
