I am installing a rubicon express 3.5 standard lift here in the near future and I was going to use the cam bolts that come with the kit in favor of buying new control arms. Mainly due to cost. I have since come up with some money and since everyone voted for using new arms vs cam bolts I am going to purchase some so I don't have to booger up the mounting locations.
I have a couple of questions though. I see that the kit comes with lower front cam bolts and upper rears. I know little about suspension geometry so stay with me here. Is it acceptable to just get adjustable lower fronts and upper rears to correct castor and pinion angle? That would save some cash for me.
One other area of concern is the suggestions on the RE website suggesting that with their "superflex" (which is just the standard with control arms for the most part) a sye/cv is recommended in the front and may be required in the back. Do the control arms add that much more flex? I'm not really looking for more than what the standard kit would give. Just wanting to have proper pinion angle and castor. Once again can I get away with just the front lowers and rear uppers to negate the need for driveline upgrades at this time.
Last but not least I have heard of issues with the RE arms at one point. Looking for arms with good quality joints. Any suggestions on brand? Thanks for any input you all can give.
Edit-- I will have a pretty heavy rig out on the trail with all the metal bumpers,winch,gear,full skid protection ect. so I might have less actual lift when doing heavy wheeling if that matters for the driveline question.
