Hey guys... I am having a real delima over this current upgrade I am about to perform. I have a 1997 FJZ 80, OME 851/860 with N73/N74E Nitro's. The springs have 100K on them and I want to stiffen the suspension back up like when the OME suspension was first installed back in '97. I am running BFG A/T 33" tires and they seem to be a good combination. However, I would like a little more lift and am considering going with 35" BFG A/T's pretty soon. I have already ordered my suspension parts which will be here tomorrow...
Here is what I decided to go with...OME 850J/863J and N73L/ N74L Nitro's. I have an ARB Bull Bar w/winch mount but no winch at this time but will have one soon. I have stock rear bumper but plan on going with one of the rear steps with tire/cooler mounts. May some day go with the long range fuel tank but not a priority as of now. And I have a full length roof rack which I load down all the time.
With this being my current set up, I now have concerns about changing how the vehicle handles, i.e. Caster alignment primarily. I do have the OME replacement bushings already installed but I understand that they only give about 2 degres adjustment and perhaps the additional heigth provided by the J springs will put the caster way out of alignment. Also, I read where there may be drivetrain vibrations added due to the extra height. And I fear that there will be several other modifications necessary in order to get the vehicle set up correctly.
Also, if I do go with the 33' tires, will I need to change my gearing and speedo gear? I was told that with the 35", the transmission may not shift as well eitheI just want my Land Cruiser to be pretty agressive and capable of handling most off road situations as well as handle like it does now on the highway. My current setup is good now and has worked very well but I just would like a little more aggressiveness. I would love to hear what you all have found in your experience so I may make an educated decission. I may have to just try it and see for myself and make changes from there. Thanks for any advice given.
