I took my 80 to a shop and the guy fit new Koni Heavy Track Raids with TJM Extra Heavy Duty Coils that give a 7cm lift, castor kit and new steering damper. He also changed all of the brakes, and removed the factory tires and put on BFGoodrich All-Terrains of the same size (but with the tread I think they add an inch to or two to the diameter). He also changed the fluids, overhauled the axles, and changed all belts (including timing).Upon receiving the ruck yesterday it sure feel likes the truck has less power, and the brakes to don't seem to work as good as the old rusty ones. Before I get paranoid and begin following the train of thought that he swapped out my turbo and gave me crap brakes, I figure I should ask questions about mechanics and physics, etc. With the changes listed above, could I feel perceived losses of engine and braking power? If the tires are bigger, would that require the engine to use more power to turn them? Even if they are marginally larger? I guess a better question would be how big would the tires have to be for me to notice a drop in performance? Gear ratios? What about braking? I guess maybe the lines would have to be longer to reach the calipers now? Could their not be enough fluid, or some other change that has caused the brake performance to suffer. It is all quite noticeable and it began to agitate me to day as I was driving around, plus the rear left brake was sticking yesterday. I hate being without tools and space to work. I hate more not having knowledge. This weird combination has been hard for me to find on the web and forums. Any thoughts?
