Nay said:I respect your experience, and I think you are dead on if you want to return your vehicle to its stock characteristics (although at 10 years I think you need to replace all wear components to accomplish this). The idea of "perfectly matched" implies that the stock characteristics are the most desirable possible for every type of usage, which is impossible. In the North American market, SUV's are almost univerally tuned to be too soft, because "ride" is paramount for those four wheel drive commutes with lattes in tow.
I was going to post almost the same exact thing. Stock is optimized for some mythological average consumer. That's not always what every consumer wants. That's why Billies come on the TRD trucks - slightly different consumer. I'd also guess that 80% of the people on this list use their 80 series a little differently than the target consumer for a $55,000 SUV. What is optimum ride for this small percentage of consumers, is somewhat off from what the "average consumer" wanted when Toyota optimized the system for them.
Not saying Toyota didn't meet 85-90% of the markets needs with it's settings, just that I"m probably in the 10-15% of consumers.

In the end - if the ride was perfect to you when new - go with stock. If you'd like a stiffer ride, go billies or something else.
