Wheel Alignment Turn Plates with Brass Finish Dial, 4 Ton Capacity, and Bonus Accessories (Pair)

Not so sure that they're ready for prime time yet

They don't seem very robust. They're some sort of plastic -- robust plastic, to be sure but I don't think they're going to hold up to use -- especially on heavy vehicles. Also, they are not adequately marked. Center points and cross points need to be marked to facilitate wheel and tire alignment. Furthermore, the documentation really doesn't describe functionality and utility completely. Excellent product in concept but it needs refinement.

Work as they should Good quality
