Matt,
I would put the drop blocks in when the OME L-shocks are installed. You have to drop the sway bar anyway to install the shocks. Might as well wait.
If you don't want to wait then I don't see that the blocks would hurt or help the ride. All they do is lower the sway bar. It's still...
Matt,
The front sway bar drop blocks are necessary when you increase the length of your shocks (e.g. OME "L" shocks.) Stock length shocks don't require the blocks.
