Decided I wanted to go a bit lower on the rear of my A3. I've got AP coilovers so the adjuster is at the top but when using the C spanner to adjust it, the whole thing spins including the black plate at the top! I've read that this is a common problem but not read of a solution.
Any tips on how to adjust it? It's annoying me that the fronts are so easy to adjust but the backs are a massive polavour!
