Will these fit my wheel without modification?

M12 x 1.5 is a universal fitment across most cars, but verify your vehicle's thread pitch and bore diameter match before purchase — wrong sizing causes unsafe mounting.

Do these need any prep before installation?

Clean the wheel bore and lug seat on your hub to remove dirt and corrosion. Check that lugs thread smoothly by hand before tightening — if resistance is high, stop and inspect the threads.

How tight should I crank these down?

Refer to your vehicle's service manual for torque specs — over-tightening strips aluminum threads and under-tightening risks wheel looseness. Use a calibrated torque wrench, not feel.
