I installed on mu 2007 fortuner old man shocks and eibach springs but was not really happy. Then after a year i removed the springs and returned the stocks springs and old man shocks, which made it better but not better than my 2014 fortuner
Old Man Emu was okay onbour LC80 and Everest before. Lasted not as long as id hope though. Using Ironman on the LC80 currently and im satisfied. Priced lower than the OMEs even. Cant say how it will be on a Fort though. Im used to stiff rides and hard tyres as well so my measure of comfort may be different.
I have IronMan on 2 rigs (Gen 2.5 Paj and LC100 and OME on one (LC 80). You wont go wrong with either. Although I would go with IronMan due to the lower cost.
