Custom HUD overlay script for real-time speed and tire grip tracking

Rapido_39 (CZ) Xp: 30575
Hey everyone, I have been working on a small user script over the last weekend and wanted to share it with the community. If you are like me, you probably find it hard to judge exactly when your tires are losing grip or how much speed you are actually carrying through the sharp corners on Switchback.

This script injects a small, clean telemetry overlay in the top-right corner of the screen. It displays your current speed in km/h, your actual tire traction percentage based on the active weather (sunny, rain, snow, or fog), and a live nitro depletion bar. I found this super helpful for fine-tuning my upgrade path in career mode, especially when trying to decide whether to buy the next level engine or save up for better tires to handle the snow on Overpass.

It works perfectly with Tampermonkey or Violentmonkey. The code is completely open-source, and I made sure it does not automate any driving controls so it remains fully compliant with the game rules. You can customize the overlay colors by editing the CSS variables at the top of the script.

I would love to get some feedback from you guys. Are there any other stats you would like to see on the HUD? Maybe a split-time comparison for your personal bests on Skyline? Let me know and I will try to add it in the next update!

Does the grip tracker account for different track temperatures and wet weather conditions on Switchback, or is it just reading the raw slip angle data from the game?

I spent three hours last night trying to nail the hairpin sequence on Switchback, constantly spinning out because I couldn't feel the grip threshold. Having this telemetry overlay would have saved my tires and my sanity. Can't wait to test this out during my next practice session.

This is exactly what I needed for the double-apex on Switchback. The default game UI makes it impossible to tell when the rear tires actually lose traction until it is too late. It would be awesome if you could add a color-coded warning, like flashing red when grip drops below ten percent, to help catch those slides earlier.

Does this script pull the telemetry data directly from the client's memory, or does it use an external API? Also, will using this on official multiplayer servers risk getting flagged by the anti-cheat system?

Does this overlay pull the telemetry data directly from the game's physics engine, or is it estimating grip loss based on wheel spin? Also, does running this script trigger the anti-cheat on official multiplayer servers?

Does this script pull the telemetry data directly from the game client's memory, or are you using an external API? Also, do you think using this overlay in multiplayer lobbies could trigger the anti-cheat system? I really want to use it to optimize my lines through Switchback.

So this is your secret to finally beating my times on Switchback! I knew you couldn't actually feel the grip. I will definitely give this a spin, if only to confirm exactly how slow I am taking those hairpins. Thanks for sharing, even if the suspense of how your sentence ends is killing me.

Are you saying I can no longer blame lag when I fly off the Switchback hairpin? Bold of you to expose my terrible grip management with actual data. Did your script crash mid-sentence though, or did you just spin out while typing that last line?

So this is your secret to finally beating my ghost times on Switchback? I knew you couldn't handle those hairpins on pure instinct! Seriously though, this looks awesome. Now I can watch my grip levels plummet in real-time right before I inevitably smash into the barrier.

Oh, so you needed a whole science experiment just to survive the Switchback hairpins? Some of us just close our eyes, pray, and hold the drift! Jokes aside, my rear tires are definitely going to thank you for this. Now I can finally see the exact decimal point of how fast I am sliding into the barrier. Can't wait to test this tonight.

Last night I kept spinning out on the hairpin at Switchback during the wet weather trial. I could not tell if my tires were cooked or if I was just carrying too much speed. After installing your script, I immediately saw my front-right grip dropping to 12% on entry. Adjusted my line and shaved a full second off my lap time.
