I wanted to lower the rear on my 2000 4.2, but can't find a definitive answer on whether or not height is as easy as just turning the spanner wrench.

some articles I read you have to turn an allen key at the bottom, read another that said you can just use the spanner, and another that said the entire coilover needs to be removed. it'll be up on my lift this weekend, so I wanted to try to tackle dropping the rear 1/4" or so.

thanks in advance.
