Hi Martin, I got your email this morning and replied to it.
Droped spindles are nice but there is no adjustability, If your not happy with the height you can't raise or lower it. The Adjustable beams are nice but do take a little longer to install , I think that pay's off when you want to go on a long road trip and need extra ground clearance (going camping down dirt roads).
Either way I can help you with any parts you may need.
Geoff.
