I always thought the TRD suspension was a bit stiffer. I know the ride height is the exact same, but I was under the understanding that it had greater load capacity. And, by the way, the Tokicos are the TRD equivalent for the 4-door model, not the stock model. The stock models have every day cheapy oil shocks.
I'd say that $100 is a damned good deal for TRD suspension with low miles. The new shocks alone would be worth at least $60 a pop.
