How do you tune your cars? This has been a well known secret for a long time. Robloxian Grandprawn created the method of tuning cars in Street Racing Unlesahed. Back to the question, how do you tune your cars? The answer is: Materials! Materials help with your tuning, aka it actually tunes the car. To have overall a perfect Charger, the picture here shows. If you look closely, you should be able to identify the materials. But for reference, the materials are: Wheels = Plastic. Axels = Grass. Middle = Wood. Back block = Wood. Front block = Metal. To tune other cars to get the perfect tune, play around with the materials! I really hope this guide helps, and you become a tuner, and not those pesky ricers.
