5100s are my plan as well. I knew that ZR2 shocks would be expensive, but not that much.....ugh
Nothing wrong with going to the 5100's. Besides you can replace all 4 of your 5100's 9 times for the cost of the ZR2 shocks which IMHO are way overrated for the price they want for them...If you want to spend that kind of money go out and buy some custom made King off road shocks, at least they are rebuildable.
