I know there is a good aftermarket segment for the IS300. Did they get lower gears for the rear differential? I wonder if the day will come where we get them for the IS350. In my opinion this is one of the cheapest and best mods you can do for your vehicle. Sure I know it doesn’t add horsepower on the books but it makes it feel like you added a whole lot. I would be more then happy to give up 20 mph on the top end to get it back on the bottom end. This makes your 0-60 and quarter mile times much better. Also did they make a program or adapter to correct the speedo after doing so? I wish the performance market would get off there butts in regards to this car. I want to get into the 12’s with a lexus!
