0 0GT7 update 1.72 changes the default suspension and differential settings for every Gr.1, Gr.2, Gr.3 and Gr.4 cars. That's the biggest news for racers in Spec IV Part 1, and Polyphony left it near the bottom of the patch notes.
We covered the six cars, Sportsland SUGO and the headline features when the release date was confirmed. This piece is only about what Polyphony revealed when the update went live on 15 October, from the official 1.72 update notice and Spec IV Part 1 announcement.
New default setups for Gr.1 to Gr.4
Polyphony has changed the default suspension and differential settings for all four racing categories. It hasn't said what changed or by how much. That sounds like a small line in the notes, but it isn't, because most Sport Mode races run with tuning prohibited. When you can't touch the setup, the default is the setup. So every Gr.3 and Gr.4 Daily Race from now on runs on cars that handle differently from last week.
That matters because Gr.3 is the category GT7 players race most. Across the last 90 days on our event statistics page, Gr.3 accounted for 18 of 57 events, more than any other group. A change to how those cars rotate or put power down could reshuffle a meta that two cars have owned for months. We expect the effect to show in the car usage numbers on the first Gr.3 Daily after the update. When a default setup changes, the cars that were on the edge tend to move first, either into the window or out of it.
Ballast has new limits
In Car Settings, lighter cars may now be limited in how much ballast they can carry, and where you place it may be restricted to keep the front-to-rear balance within a reasonable range. This mainly affects tuned events and custom lobbies, where heavy ballast placed at one end of the car was a known way to change how it behaves. If you have saved setups that used a lot of ballast, check them before your next league race.
Force feedback changes and new wheel support
Force feedback has been revised for the Thrustmaster T598 and the Logitech RS50. If you race on either, check your settings: the same numbers may now feel different. We found the T598's force feedback faded as the base got hot in our review, so we're curious whether this changes how it feels over a long race.
GT7 also now has native support for the Moza R5S Pro Racing Simulator, before the wheel itself is on sale. MOZA Racing has been added to Brand Central and to the preset decals in the Livery Editor too, which fits with Moza becoming a World Series partner and revealing its first PlayStation wheels.
SUGO in numbers
Polyphony has now published the official figures for the new track. The lap is 3,586 metres with 13 corners, 69.83 metres of elevation change and a longest straight of 704.5 metres. The final corner climbs at up to 10 percent onto the pit straight. That's the corner most people will be learning first, because it sets your speed for the longest straight on the lap.
Nine new brands and two new museums
Brand Central adds Autobianchi, De Tomaso, Jeep, Lancia, MOZA Racing, Pontiac, Plymouth, Shelby and TVR. There's a new Jeep museum in the United States and a TVR museum in the United Kingdom, plus new Related Spots for Mazda.
Experience, the new brand challenge mode, launches with four brands: Xiaomi, Yangwang, Hyundai and Polestar. Xiaomi was expected given the Vision Gran Turismo launch. The other three are a sign of which manufacturers are working most closely with Polyphony right now.
How Vintage and Car Concierge actually work
Vintage shows cars from 2000 and earlier inside each brand's dealership and takes you straight to the Legend Cars or Used Cars dealership to buy them. It's available for 41 brands, from Abarth to Volvo. Car Concierge lets you order a Vintage car by model, colour and condition, and it searches for a match for you. You can have up to four orders running at once, depending on your Collector Level. It unlocks after you finish Menu Book 39, the World GT Series championship, and watch the ending.
Legend Car prices are also changing. Polyphony is repricing the Hagerty Collection to match Hagerty's real-world valuations. New prices apply the next time each car comes up for sale, and the next revision is scheduled for March 2027. If there's a Legend Car you've been saving for, its price may change when it next appears.
Café, engine swaps and smaller additions
The Collector Level cap rises from 70 to 90, and three new Extra Menus are tied to it: High-Performance EVs, Tuned GT-Rs and Le Mans Winners, at levels 70, 80 and 90. A new Seasonal Menu changes the cars you collect each season for extra rewards. There are also new Café conversations, including Ferrari designer Fabio Filippini when you bring the F355.
Engine swaps arrive for ten cars, unlocked at Collector Level 50: the three new Citroën and Honda models, the Mazda RX-Vision '15, the Mini Cooper S '65, the Peugeot RCZ Gr.3 Road Car, and four Lamborghinis (the Aventador, Diablo GT, Gallardo and Murciélago).
World Circuits gets six new events. Three are at SUGO (European Sunday Cup 400, and World Touring Car 600 and 800), plus a Vision Gran Turismo Trophy at Spa, a European Clubman Cup 600 at Dragon Trail Seaside Reverse and a Sunday Cup at Autopolis. Scapes adds Angeles Crest Highway and Sportsland SUGO. The title screen now uses artwork inspired by the first Gran Turismo for the 30th anniversary, and the world map has a new Your Recommendations area.
Final Thoughts
The cars and SUGO will get the attention, but for anyone racing in Sport Mode the default setup change is the update. Every Gr.3 and Gr.4 car you race this week is a slightly different car from last week, and Polyphony hasn't said which way any of them moved. That's what our data is for: the car usage numbers on the first post-update Dailies will show whether the meta has shifted or simply settled.
