I've got the full orange Poly kit installed on my 2006 LR3 since 2014. Good thing you're doing it yourself because labor on that job is expe$ive as heck.
My review is this: my truck now feels like a large heavy sports car. The ride is very firm and almost harsh at times (on bumps) when I run my 255/50/20 Nitto's (again, think sports car), but with my 275/65/18 Wrangler M/T's the ride is great. I don't have the squeaks that some have complained about and I off-road somewhat hard in/on rocks/mud. I thinks it's all good and would recommend it. My hope is that they last a very long time and I won't have to deal with bushings for a while.
Let me know if there is anything else more specific you'd like to know.
