I purchased a stock electric 2014 ezgo RXV last year and shortly after installed a Madjax 6" A-arm lift kit. I love the raised look but it rides like a log truck unless loaded with four adults as the suspension is way too stiff. Also, the shocks hardly dampen the suspension recoil. I intend to buy the Jake's travel suspension package for the front but it looks like I'll have to custom fabricate a new rear suspension as there doesn't seem to be any kits for the rear other than basic leaf springs which I want to steer away from.
I've been doing a lot of research and have decided to fabricate a 4-link setup for the rear. I'm not too worried about achieving the correct geometry, fabrication, etc. My biggest concern is making sure I get enough suspension support to allow for four adults while at the same time not a super stiff suspension with only 1 adult on board. I've been looking at many shocks/coil-over options and think I've found the right solution.
After some research and calculations it appears I'll need springs w/ approx. 125 lb spring rate (I figure the cart will weight approximately 1500 lbs with two adults and a child). I like the Monroe load adjusting shocks; however, the max spring rate they offer is 60 lbs. After speaking to a Monroe rep on the phone it looks like I can easily remove their spring and replace with an aftermarket spring properly rated for the load.

These are also an option but will be double the cost of the Monroe shocks. I really like the adjustability though as you can adjust damping strength:

What do you guys think? I appreciate any opinions as my family and I ride it almost every day of the week and I really want to improve the ride.
One last thing...anyone out there who's installed the Jake's long travel kit who has an opinion on quality of the kit and how much wider is the wheelbase once installed?
