Yeah. I didn't know until I installed my lift also - I only researched available lifts...didn't find useful forums until well after install.
I almost pooped myself the first time I took a speed bump a little fast. I found that slowing down for bumps/drops and avoiding potholes has helped a lot. I don't think the spring rate of the coils helps with forcefullness of the topout either.
I've had this lift for 3 years now and it has made it through quite a bit of off-roading, now I'm starting to piece together a sub frame drop (4") to get some better off-road prowess.
Alex is right though about the amount of information for the R50 on forums - NPORA, NICO, or even smaller clubs (e.g. Ronin Wheelers).
Good luck.
