Review on 🔧 Maximize Performance with Tein Adjustable Wrench Coilover Systems by Tiger Carpani

Bought these to adjust the Tein Flex Z coilers that came on my used car (keys not received with car). These wrenches worked, but they only have one tooth on one end, so only one hook point (a quick search shows many/most box wrenches have TWO hook points). It was ok for 3 of the 4 lock rings I had to loosen, but one of my coilovers was so tight that the wrench's only engagement point was a major disadvantage. Keep slipping and couldn't get enough torque on the ring. I was FINALLY able to loosen it after spraying it with a PB blaster, letting it sit, then gently holding the wrench while I hit the handle a few times with a rubber mallet. With this technique, too, the single tooth of the key kept slipping off, and the fixed ring only came loose after about 20 hits.
