I don't remember your mods, but if you are in that 400hp range and ripping your tires, then you see a difference in the wavetrac. If you are stock or close to it, you won't see a big difference unless in a situation you need traction, like slick roads and such. And even then, you won't see any difference if your traction control is on. This is a great mod for those who push their cars to the limit out of the hole. Therefore not worrying about losing the spider gears with the hard launches.
