I'm going to be putting on 4 new OME firm shocks on my 2000 4Runner next month and I'd like to try and balance out the suspension while I'm at it. I love the OME HD setup that I've got but the driver side rear is 1/2" lower than the passenger side rear when the fuel tank is all but empty. It's not really noticeable but I'd like to put an OME 5mm or 10mm spacer on that side. The driver side front is a bit more than 1/2" lower than the passenger side front and is pretty noticeable. I'm going to be designing a dual battery setup and that will add a good 40+ lbs. to the driver side front so I'd really like to fix the sagging again with either a 5mm or 10mm OME spacer if possible. Does anyone know who sells the spacers? 4x4 Connection doesn't and Rocky Road Outfitters only sells 5mm spacers for the front and nothing for the rear. Anyone have any other suggestions for a fix? Has anyone else dealt with this on their 4Runners? Of course you don't notice any difference off road just on but I don't have the luxury of living life off pavement. Any suggestions are appreciated. I've considered going with adjustable coilovers up front but they simply aren't cost effective.
