The Skyline development and the new GTR might be a better example of technology advancements. Or new style injectiors. Almost all of us have made modifications to our old cars based on newer technology. You have listed some pretty convincing reviews, and I suspect they are great tires. I buy the old model of golf balls on sale all the time and they are usually great for the price. In fact, there are probably older Titlests that are better than the newest top of the line model from another manufacturer.
