No doubt it would help on 2WD cars, but probably not much if your track grooves up to medium traction or better... it will make the most difference in high speed corners and slippery chicanes... though most clubs in my area only allow gyros in the novice classes, so might want to check your club for rules there. We did have a spec class for the Losi Mini-8ight which came with a gyro and was allowed, but the class never really took off due to durability issues on the platform
