I agree providing you have the necessary tools (spring clamps and ramps) the suspension can be installed and configured by yourself, my brother and I fitted a G-max sports kit (shox and springs) in a day and just had the camber and balancing done professionally and thats it job done...NB might be worth doing the bumpstops too, as they tend to wear and while the whole suspension tower is disassembled its a job worth donig
