Hey everyone,

I run a small GT7 YouTube channel and after getting some tuning questions on a recent video, I decided to put together a proper reference document rather than keep answering the same questions individually.

I went through everything I could find from FILO Engineering, DG EDGE, Coach Dave Academy, Doughtinator, Traxion’s FWD guide, and a lot of threads on this forum (the LSD guide summaries thread, Praiano’s tunes, and several suspension tuning discussions were particularly helpful). Cross-referenced where sources agreed and flagged where they disagreed.

The result is a 19-page PDF covering every tuning parameter with starting values tables, organised by tire compound and drivetrain layout:

• Full tuning order with reasoning
• Ride height, natural frequency, ARBs, dampers, camber, toe, aero — each with baseline values and adjustment logic
• Complete LSD section by drivetrain (FR, FF, MR, RR, AWD including center torque split) — this was the biggest gap I found across existing guides
• Transmission setup step-by-step
• Troubleshooting reference: 10 common problems with prioritised fixes
• A printable master baseline table

The target audience is beginners who’ve bought Fully Custom Suspension and LSD but don’t know where to start. That said, I’d really appreciate feedback from the more experienced tuners here — if any values are off or if I’ve misrepresented how a parameter works in GT7’s physics model, I’d rather know now than have people running bad setups.

PDF download:

Free to share. I’m also working on a web app that’ll generate custom tunes based on car specs, track, and driving preferences — so any corrections or suggestions will feed directly into that.

Thanks to everyone on this forum whose knowledge went into this. Happy to discuss any of it.
 
Question, how did you come up with the numbers for starting values?

I can see you’ve used ChatGPT quite a lot for this.
The use of the extended dash, front camber for turn in is from other sims while GT7 is more mid corner for it.
Tuning order on page 3 and the rest of the document don’t follow the same order. Using the speed lower rear ride height trick works for old GT games not GT7. Your ride height section doesn’t cover that in GT7 wheels ca rub the arches and prevent turn in if you lower the car too much, ChatGPT doesn’t know this but people who play GT7 would.

Thanks for replying, I've already started making edits based on your points.

The starting values came from cross-referencing the sources I noted in the post. Where there was congruence I used it, where there was disagreement I went with the majority. I can't claim I've personally validated every single value across every drivetrain and tire compound though - that's partly why I posted it here.

Yes, I used AI to help organise and format 19 pages worth of material - the em dashes gave it away, fair cop. I'm a time-poor dad so it's a big help for pulling a large document together consistently. The research, source selection, and cross-referencing was done by me. The AI helped structure and draft sections based on my notes.

On the specifics:

  • Tuning order inconsistency: updating now, good catch.
  • Front camber being more mid-corner in GT7 rather than turn-in: that's a useful distinction. Can you point me to any resources or testing on this? I want to make sure I'm as accurate as possible.
  • Negative rake for top speed: this was referenced in a few sources but if it no longer applies in current GT7 I'll update it.
  • Wheel arch rubbing: it is mentioned in the ride height section but you're right, it needs to be more prominent. Moving it to the top as a warning.

I'm not claiming to be the definitive tuning expert. This guide is designed as a starting point for beginners, and I'd rather put something out and get corrections from people who know GT7's physics better than me than wait until it's theoretically perfect. So genuinely, keep the feedback coming - if you've got corrections based on testing I'll credit you in the next version if you ok with that?
 
Definitely a bit of AI, even in the research too, as ride height and so on is years old and not currently in the game, as also mentioned by CTRL, but...

respect for trying and doing such a thing! Especially for beginners and people like me, who just can't get anything right with tuning.

Respect also for not just making another video, as a YouTuber!

Having this PDF on my phone while playing would be much more helpful than clicking through videos.
 
Thanks mate…That's exactly the idea something on your phone to quickly reference

The sources were GT7specific (in op), but theres most likely some thats not at the latest patch if things aren’t matching up, that's a blind spot for sure.

If yourself or anyone can flag things that aren’t applicable I'll keep revising, I already pushed a v1.1 from this thread's feedback. I’ll keep testing and refining also so it’s as accurate as possible.

And I appreciate the kind tone in your reply 🫶🏽

Where did you get theses sources from though?

Your document has 3.5 and 3.7 HZ starting values for Racing Soft/SS tyres (Hi ChatGPT again with this naming error and only producing one decimal point)
Not every car has the same value range for settings, most road cars don’t even get to 3.50 and then some race cars go all the way to 5.00.

Ride height has the opposite where 85mm rear ride height for racing tyres might work on road cars but most race cars this is at max.


Sorry but I’m just skeptical as It looks like you’ve gone “Hi Chat, GT7 has these tuning options, make a comprehensive guide for beginners with suggested values” and now plastered this on the internet without checking the effects of these changes in game.

There are other issues with the document but I’m not going to help sort AI slop, it’s quite clear AI wasn’t used to just reorganise data/format your document. This is a quick move to try drive traffic to your YouTube channel.

Fair points on the NF ranges and naming those are errors I should have caught by checking against in-game UI rather than relying on written sources alone. I'll correct them.

I hear you on the skepticism. I was upfront about using AI to help with this, and clearly some GT7-specific number details slipped through that wouldn't have if I'd validated every value in-game. That's on me. I'm going through all this in detail now.

If the community feels this isn't helpful or is doing more harm than good, I'm happy to take it down. No ego here - I'd rather remove it than have beginners running bad setups.

Appreciate you taking the time to point these out.

Ok but again what sources gave you 3.5 and 3.7 for starting values on RS tyres?
Click to expand...
Honestly, no single source gave those exact numbers. The sources gave principles (stiffer for racing compounds, rear slightly stiffer than front) and I extrapolated specific values from there. As you pointed out was the wrong approach, many cars can't even reach 3.5. I've rewritten that section in v1.2 to use slider positions instead of absolute values is scalable, it is what I should have done from the start.
 
UPDATE - v1.2 now live (same link):

  • Tire names corrected to match in-game
  • NF and ride height sections rewritten to use slider position instead of absolute values (ranges vary too much between car classes for fixed numbers to work)
  • Damper values corrected
  • Wheel arch rubbing, camber mid-corner framing, and section order all fixed

Thanks for the feedback.
 
Quite an influx of 'new' IDs around here lately, all private PSN, not much activity, all speaking very similiar when posting, but not actually posting anything they have specifically done themselves that can be proved....

GBR Winny V2.0?

Or whoever is behind that, hiding behind a VPN looking to stir things up...... Geee, let me see, who's got quite a history of doing this type of thing.

Maybe he was a fan after all ;)
