Well pardon me for English being my second language. Let me try again.You never said anything about compression specificlly either, you said "easier to change the setup". Does rebound not count as the setup? Because it does for the BPs, so if we're comparing apples to apples it's not as easy with the Icons.
Right, he asked for opinions on BP-51s, not comparing to a kit that costs over twice the price. I don't see where the OP mentions Icons at all...
BP-51 changi thingies harder than Icon single changi thingy.
And just thoughts just on the BP's.
I would have kept the BP-51 if they were not Clunking, creaking and groaning and overall felt like the whole front end was falling apart on small bumps. Thankfully ARB has a great customer service and after sending me another set that had the exact same problem, they took them back.
I heard they finally corrected those issues.
