LOL yeah for cars specifically wide body is is definitely the best. I tried to make the testing as robust and consistent as possible, glad you enjoyed and thanks for tuning in :)
One big thing of widebody is, that for a lot of cars you get different, with more downforce possible, splitters, side skirts, wings and even diffusers on some cars.
I want to add something I've found out while making my cars, for Example: The R32 GTR and Countach 25th, without the widebody fully tuned have steering issues where the wheels dont completely turn, when you do widebody both cars the turning is noticeably sharper and has more of a radius. idk what cars it works on, but those are two that I actively know.
Probably because you have racing suspension and you lowered your car too much. With a widebody it flares out the fenders and allows the wheel to turn without rubbing the body (which would cause steering issues)
The tire rubbing on the body is influenced by the wide body for sure! Most of the time in a positive way however some cars you will need to adjust the ride height and/or frequency to prevent the tires from rubbing against the fender
@AKKSI you hit the nail on the head. Raising the ride height in the front, stiffening the natural frequency in the front, increasing negative camber in the front, raising the damping ratio (compression) in the front, decreasing damping ratio (extension) in the rear, less downforce, less front weight distribution and especially stiffening front anti-roll bars (for cornering and body weight transfer). It's pretty awesome that they allowed so much freedom with just a few, yet complex modifications to affect the car in such a major way. When the game released, I was picking my brain out through my ears trying to wrap my head around it, but when I applied realistic and logical thinking of how suspension and weight transfer works, it instantly made sense.
Having a wide tire offset does affect the handling to some extent with cars that allow the option. The Ferrari P4 for example felt a LOT more controllable with the wide offset than without it. Plus it looks as if it was built for it too.
The wide tire offset which is the option does definitely affect performance, but I’ve never found the middle option which is the rim width to change anything personally
This is an awesome test, great work!! I will still always use widebody and wide tire. I feel the gain in grip through turns is going to out outweigh the drop in top end speed, especially such a small drop. Also that is actually beneficial on a road course, you are going to have increased braking performance. I definitely feel the pros outweigh the cons and we don't have many events that are just very long straights too often. Plus it looks much better wide!!
@@DoodRacing Yeah cheers I have seen it, my set up isn't a million miles away a part from I have more upgrades, so I may have to buy a new engine, I also didn't buy the roll cage.
Yes I did notice that, but the difference on track was not big enough for me to notice in my instrumented testing. Maybe I can find a better way to test it and make it it’s own video
I needed to see this guide! Thank you for this comprehensive guide and all the research you put in to make this video, With the newest GT7 update (As of writing this) I need to see if this will benefit my car after swapping the engine!
Was just about to say this is pretty much it, 80-90% of cars with stock tires the wide body offers nothing or typically hurts it a bit PP wise as it doesn't change the wheel spacing or size at all it just flares the body out which if PP is any indication likely just increases propensity for body roll. But as soon as you fit custom wheels you get the proper spacing and upgraded tire size, and wide tires when it works just adds a bit more.
@@DoodRacing also depends on the car. Some with wide bodies can take the aftermarket wheels wider , but not wide offset, which interferes with steering, but on most cases it certainly does help. With the wide body beetle it seemed to work well with standard wheels and wide offset or aftermarket wide wheels and no offset, if that makes sense, as it would severely understeer if I had wide wheels and wide offset 🤔
@@Bread_45 yeah I think so, as with some cars it becomes too wide and tyres seem to scrub, so I have to return to just wider wheels without the wide offset.
okay good i feel better widebody-ing almost every road car i own ahahah. i mainly do it for the aesthetics cuz i have a mental age of about 4 when it comes to modifying cars in video games, though i'm glad to see that the widebody isn't for nothing. i'm not a big Racing kind of person, i haven't really touched multiplayer or sport mode, cuz i prefer sprint races with maxed-out road cars.
I know there’s a bug at route x with the supra RZ. But this is surprising to hear to wide body is faster on their cars. I’ll probably go test that myself at some point
Amazing video! Answered all the questions I had, the only thing I still don't understand ist the body rigidity upgrad. If you or anyone else knows it's pros and cons, please let me know ;)
Purely from feeling and not so much testing, and taking input from other tuners I know. It feels like body rigidity definitely stiffens the chassis under heavy cornering, acceleration and braking loads. Essentially if you’re familiar with the anti roll bar settings, if you have your roll bars set to 10 and 10, if you put rigidity on its now the equivalent of 12 and 12. Back when suspension tuning affected the pp system, when you increased your roll bars settings on many cars the PP rating would go down. And now on most cars when rigidity is equipped, the pp rating goes down by a similar factor which kind of backs the theory I made above. On most high performance cars, and especially on tracks that are flat with very little bumps. Body rigidity is a net positive as it allows you to get a stiffer chassis which will allow for better weight transfer and aerodynamic efficiency. (which I do believe GT7s physics accounts for)
I would say in cars below 350-400hp it may be worth having the extra pp to add power, shed weight, or add front downforce. In cars above that hp, the extra low speed traction paired with the extra lateral grip from wide body is more important. Also adding 20 hp when you’re already at 700hp has less of a positive affect then adding 20hp to a car with 250hp. The higher the power level the more worth it the wide body is in my opinion.
I‘ll stick with the widebodies. If nothing else, they look good! Some are downright intimidating… Only on the E30 M3 I’ve got one wide and one stock. For authenticity, when they first entered DTM they were stock. It’s a bit more playful around corners. But other than that, wide. The De Tomaso… jummie!
Wide bodies are my preference as well. Not only are they better performing for regular circuits but all of what you said is the opinion I share as well! Wide bodies look incredible
I did test the top speed with a few higher performance cars and the trends remained the same. As far as the grip test there may be some slight differences but for race cars you can’t equip a wide body so I left those out. This is more for road car builds
I do not believe rim width changes pp on any car I’ve tried. the offset (the option to the right of that) changes the pp though. as well as a small difference when changing the rim size from default
In my next video I’m going to recommend a few setup adjustments from last update to this one! So not quite a full guide yet but Stay tuned because it should help a lot
Is it possible that the widebody affects the maximum speed of a car? I was testing the Porsche Cayman GT4 with the engine change, and they are telling me that having a widebody on it is affecting my top speed, but I don't know how true that is.
I understand, thank you very much for clarifying that for me, and increasing the rigidity of the body, does that also cause it to go slower, or does it not affect the car as much?@@DoodRacing
@@Fran-351 Body rigidity makes the chassis more stiff and reduces overall body roll. It has a similar affect to anti roll bars based on my feeling. Although i haven't done a detailed test on this.
At the one minute mark you are saying that the wide rim offset does nothing. But you are not red-marking the offset but the rim width. Please clarify, is this a video error you made? Just want to be sure as my english is not that perfect.
thx man, I BEEN WONDERING ABOUT THIS🤘but why did u ONLY USE 1 CAR?u should do 1 with FR DRIVE, REAR WHEEL DRIVE AND ALL WHEEL DRIVE. USE A NID-ENGINE CAR ALSO
It would’ve been ALOT of testing to account for all the cars. But the general trends are the same. Since the wide body modifies aero, most cars react similarly to the change. Although the 4WD cars may benefit less from the wide offset since they have better low speed traction out of the box
I am a wide body guy! When it comes to cars, at least. It's good to know that my gut feeling could be tested in so much details. Thanks for the video!
LOL yeah for cars specifically wide body is is definitely the best. I tried to make the testing as robust and consistent as possible, glad you enjoyed and thanks for tuning in :)
One big thing of widebody is, that for a lot of cars you get different, with more downforce possible, splitters, side skirts, wings and even diffusers on some cars.
Yes exactly, these results will vary based on the car used as well as parts selection. However the trends should remain the same
Never knew this. I'm still finding stuff out about this game even after 2 years.
I want to add something I've found out while making my cars, for Example: The R32 GTR and Countach 25th, without the widebody fully tuned have steering issues where the wheels dont completely turn, when you do widebody both cars the turning is noticeably sharper and has more of a radius. idk what cars it works on, but those are two that I actively know.

A good watch! Nice clip selection! Didn't expect this from the widebody. Thanks for this. I always use widebody.
Haha a lot of the clips had the PRT guys in there. Glad you enjoyed though bro!
God-level tutorial tbh 🔥🤘
I appreciate it!!!! Glad you enjoyed
Interesting considering the current time attack at Laguna which I'm still trying figure out a good set up

There is a light difference as well when choosing the rims diameter , some cars get more PR with small rims

From the visuals it seems tire width only increases with wide body if you put on aftermarket rims (note it’s very obvious on cars such as the pantera)
This would make sense given the cornering performance difference between those options and everything else.
Was just about to say this is pretty much it, 80-90% of cars with stock tires the wide body offers nothing or typically hurts it a bit PP wise as it doesn't change the wheel spacing or size at all it just flares the body out which if PP is any indication likely just increases propensity for body roll.

Dude, the detailed video was awsome, keep it up

Your content is amazing
I really appreciate it man! Hope you found this helpful
Great content! Great video 👍
Thank you bro! Much appreciated
My understanding is that the offset simply widens the track of the car, which helps when using standard wheels.
It definitely helps a lot. On cars with wide body equipped it basically accounts for 90% of the performance increase.
@@DoodRacing also depends on the car. Some with wide bodies can take the aftermarket wheels wider , but not wide offset, which interferes with steering, but on most cases it certainly does help. With the wide body beetle it seemed to work well with standard wheels and wide offset or aftermarket wide wheels and no offset, if that makes sense, as it would severely understeer if I had wide wheels and wide offset 🤔
Is it possible that the offset option, actually gives a wider offset when wide body is already equipped?
@@Bread_45 yeah I think so, as with some cars it becomes too wide and tyres seem to scrub, so I have to return to just wider wheels without the wide offset.
Great vid, noone else covering this. My engine swapped 370z is gonna get wide!
Haha that thing is a beast! Looks super mean wide too
The width of the rims is actually affecting performance but you can only feel the change when driving. No PP change
I’ve never felt the change personally, though I did do this test before the last physics update
okay good i feel better widebody-ing almost every road car i own ahahah. i mainly do it for the aesthetics cuz i have a mental age of about 4 when it comes to modifying cars in video games, though i'm glad to see that the widebody isn't for nothing. i'm not a big Racing kind of person, i haven't really touched multiplayer or sport mode, cuz i prefer sprint races with maxed-out road cars.
I’m the same way, lobby racing is super fun and modifying cars is honestly the thing that keeps Gran Turismo fresh for me
Depends on certain cars. Supra RZ widebody has a faster top speed than its slimbody counterpart. As well as MR2.
I know there’s a bug at route x with the supra RZ. But this is surprising to hear to wide body is faster on their cars. I’ll probably go test that myself at some point
@@DoodRacing There is a glitch tune for Supra. But without the glitch tune it's still faster than slim body.
Thank you so much once again for the work that you do for our community, love it ❤
Like deployed 👍
Appreciate you man! Thanks for the kind words

@@RealLifeLuca yes for sure
@@DoodRacing thanks for the answer
Nice video. Subscribed.
Can you do a comparison between racing manual and full race gearboxes
This is a good idea. I’ll start doing some testing soon.
When you do a wide body and buy a new body from the shop it comes wide body, even though a new body should be factory.
Once you wide a car thats it
Yup I learned that the hard way with my bugatti Veyron lol. Interesting decision they made considering new body reverts everything else to stock
I spent like 400k on a new body for my 964 porsche and it was still widebody i was fucking pissed lol
Just great. Thanks. I'll just stick with the wide bodies, simplifying my life.
Yup definitely faster on all tracks except the ovals. And they look good too! Thanks for watching man :)
Do the ford gt40 mk1 please i need to justify the 100k or 10k
I use it for 750pp and 700pp and it’s amazing. I’ll do a vid on it eventually
@@DoodRacing yes daddy
Thanks for the good tips 😉👍
No worries man! Glad you enjoyed :)
Excellent video! But what else would I expect from the guy who had the level of game knowledge to dominate race car lobbies in a Mini Van back in GT6.
HAHA never forget the Audi SUV
Great video!
Thanks man! Glad you enjoyed :)
Very helpful thanks!
Glad I could help man!!!!
Now here’s the big question, is the improvement in grip and hit in top speed worth the 5PP hit vs using that towards lower weight or more power?? 🤔
I would say in cars below 350-400hp it may be worth having the extra pp to add power, shed weight, or add front downforce. In cars above that hp, the extra low speed traction paired with the extra lateral grip from wide body is more important.
Also adding 20 hp when you’re already at 700hp has less of a positive affect then adding 20hp to a car with 250hp. The higher the power level the more worth it the wide body is in my opinion.

Are the effects still the same after update 1.49?
It appears as though it’s the same trends, although the differences seems slightly less apparent
less gooo

How do u get rid of wide body?
Unfortunately it’s impossible. You have to buy a new car
Yeah cause I messed up my ZL1

How do you get the wide body off ?
You can’t unfortunately. You have to buy a new car lol
Did the 1.31 update affect this?
I may affect the exact values. But the principle and trends should be exactly the same.
so where's my comment gone? strange I put a interesting link on to twitter and comment gets deleted 🤔
Honestly I think TH-cam may have deleted it because of the link. I would never do that so it must be TH-cam
😂 youtube are happy to be on twitter tho, gobshites!
Need top speed, don't wide body. Need grip and turn, widebody
Also for short straight line races like 1/4 mile, wide body is faster
