Ive got no understeer issues. none that aren't "realistic" anyway. controling weight transfer properly is the key.
 
Trail braking is just something you must not do with regular tires. Brake before turning the wheel, otherwise you slide straight off the track. That's also the first thing they teach you at safe-driving school. NEVER brake while turning.

wrong!

No, I think Insight is correct. Typically, if you're a beginner, you want to brake hardest while the car is travelling in a straight line. Heavy brake application combined with turning can cause the rear wheels to lock up. Once you have an understanding of the car, then you apply the brakes later into the turn.

And try to be more civil next time...

I am by no means a professional driver in RL, so don't know all the technical racing techniques, but for GT5, it might be easier to brake earlier and release the brake gradually as needed before getting to the apex of the turn, like 85% straight line and 15% turn in (I assume this is what ppl call trail braking). You would like to avoid hard braking into corners at all costs since then you are using 100% of your tires to brake, and 0% for turning which results in understeering.
 
Not only is understeer annoying, I fail to see how it's easier for the casual market. If anything, avoiding it is harder to cure than oversteer, which thanks to arcade games, the general public seem to understand more anyway.

I can't remember the last time I experienced understeer in my car, but in the two brief plays I've had on GT5, it was terminal as soon as you touched the brakes.

On that subject and before I get the game, what's the most realistic number to have ABS set to on the game? It was at +1 the last time I played it and I didn't like how it seems to lock the brakes and stop the car from steering.
 
Wow makes me wonder if people actually read the thread before posting.

It's not a setup issue
Sport soft tyres are semi slick racing tyres

Fixing your cars handling issues by throwing racing slicks on it is the oldest and laziest trick in the book. As stated earlier, my usual car is f430 Scuderia fully modified. The max amount of rubber anyone should use on this car is sports soft tyres. Slicks are complete overkill. Lastly, I've held worlds fastest times in TT's before so it's not my virtual driving technique. Again, try my car on some tracks like Rome.

In RL, it is much harder to control oversteering then understreeing. Most ppl once they oversteer, will hit their brakes, which is a big no no, will lead you to snap over and spin. With understeer, you can hit your brakes without causing a spin, it just most likely will result is a oversteer accident, which from a safety point of view is probably safer then oversteering and hitting something.
 
What has that got to do with the 'casuals' experience with racing games?
 
Makes sense to me. Understeer is definitely better than oversteer if you're a casual who knows next to nothing about car control.

I thought you were talking about why the GT5 tends to understeer. I was explaining in real life, most production cars understeer, hence that is what we have in the game.

I'm sorry but no it will not.

Heavy braking combined with turning will cause the front tyres to exceed the limit of grip, which will result in understeer.

Understeer on road cars when braking hard into a corner and steering is the natural balance for a good 99% of cars sold.

Its specifically engineered in (and a natural product of the physics involved) and as such should be happening.

Given the amount of snow and the cold weather we have had in the UK over the last few weeks I can only imagine you have not been on the road much.

I can currently get my 3 series to understeer or over steer pretty much on demand if I wish and have seen plenty of evidence of both occurring on my daily travels.

Understeer does not occur as soon as you touch the brakes in GT5, so I have no idea how you have managed to achieve this. However two brief plays may suggest that you carried far too much speed into corners and panic braked while turning late. In which case understeer is top be expected.

I've well over a decade of experience training vehicle dynamics and driving in the motor industry (both on the road and track) and the understeer in GT5 is not overdone, and certainly not terminal as soon as you touch the brakes.

Like I said, thanks to arcade games, the casual market know how to oversteer. I'd be surprised if the casual market were nuanced enough in car control to know you can bring the car up on its toes on corner entry, control the throttle mid-corner to bring the nose back in line or unsettle the car and use the understeer to pull the car back straight.

Scaff, I've mentioned on here before that I can't get used to GT5's sense of speed on the demo pod and I'd like to know how many number of settings the ABS has, as I've never locked the brakes on corner entry whilst turning and I've driven pretty hard in cars considered to be very poor (2002 Vectra for example).

As for snow, we haven't had any in Plymouth and I haven't driven in snow conditions since December last year, when I was enjoying slides at low speed.

Even the race cars entry under and snap over on exit. Eg Mazda 787B

Don't have the 787B, but since its a high HP MR, snap over on exit is going to happen. The under on entry could be somewhat cured by tuning.

This has nothing to do with arcade games and much more to do with how cars are set-up in the real world.

Understeer is easier to cure in the real world, a drivers natural response is to back off the throttle, which will instantly reduce understeer. However, even if they boot the throttle, as long as the front wheels are pointed in the direction they need to go the car will pull itself straight most of the time.

Neither of these things can be said about oversteer, which can't be controlled in the real world in the same way as an arcade game.

I've taught people how to deal with both over and understeer in the real world, and its far, far easier to get people to regain control of an understeering car that an oversteering one and the end result should you get it wrong are a lot less damaging.

Cars have a natural tendency to understeer in any halfway decent sim, simply because that's what real world car are set-up to do and the laws of physics will make most prone to do on corner entry anyway.

I find it rather confusing then that you are blaming the physics model for any issue with your ability to judge the sense of speed. As I said this means you are entering the corner too hot, not that it is unrealistic.

In regard to the ABS settings, I have no idea, I find 1 to be fine and as such have never changed it. I will try and remember to look next time I play.

In regard to having never locked up tyres on a car, that would be more indicative of your level of driving experience than anything else. Given such I find it a bit strange that you are talking with such a degree of certainty regarding how close to reality GT5 is.

That's funny, my two 'baby' brothers are at Plymouth Uni right now, one of them posted a picture up on the 2nd Dec 2010 on facebook....



...not a huge amount, but that's certainly snow, and enough to get any true petrolhead to a car park to see what a car does on the limits at slow speeds.

I havent noticed any serious understeer problems in this game. I havent tried the f430 yet though.

Its nothing like the previous games where even high powered RWD cars hitting the gas in a corner would sent it straight to the wall. I have the RUF CTR and the things nearly undrivable because it oversteers everytime I get on the throttle in a corner.

I have plenty of cars that are very tail happy. This was not the case in GT4
 
I can easily induce oversteer by braking in a regular ff car IRL. However I cant in gt5. The cars that oversteer under braking in gt5 are atleast the mr ones. But anyhow the point being that you CAN oversteer a regular ff car using braking IRL. The placement of the engine in mr cars just make them easier to oversteer with brakes.

But it seems that in gt5 i cant turn the tail around in a ff car in corners with braking wich is frustrating. I feel i am robbed of some controll over my car... :grumpy: Any car can oversteer and any car can understeer.
 
I must say that I learned a lot from this thread, so far at least. I did notice that I'm having serious grip problems when I don't put on racing soft tyres. However tho, I understand that it isn't the "real" solution for tackling this issue. I'd say that I do try to be aware to the speed I'm going in relation to the speed I might would have gone if it was RL. I'm guessing however that I got lots to learn before I get any good for real...

Firstly, i cant see where Insight mentioned "beginners".
Secondly this thread is about understeer, and light trail braking is one way to help understeer. If your good that is. no use trying this as a beginner. The light brake application can encourage weight transfer to the front wheel thus giving you more grip. Obviously heavy braking whilst cornering wouldn't be recommended.

Another thing I'm noticing is that everyone seems to go straight for suspension or tyres when trying to tune out understeer. Dont forget the affect that a wrongly set-up diff centre can have on steering. Alot of people just buy the full adjustable diff centre automatically presuming it will be better then the standard diff. Try alternating between the custom diff and the standard diff. Or try loosening you diff a little. too tight can cause alot of push through turns.

In my opinion, and it is just my opinion. For all you guys out there struggling with understeer, try to fine tune your braking. braking smoothly and gently towards the apex. (depending on the corner of course there's no Black & White rule for this) this smooth and light braking maintains constant weight transfer on those front tyres . There's a fine line you cross here though. from just right to too much. I suppose you could call this an "advanced" driving technique. It would be very hard without a wheel of course.

Also, all cars will understeer. your simply exceeding the possible front grip level, simple as that. you cant make a car on sports soft tyres do the impossible. At this stage (the limit of front grip) maybe its time to try balance the car out to your likings by removing rear grip. I race karts IRL and it pisses me off when i have to remove grip from the rear to help the front. it goes against my natural instincts, but its a regularly occuring thing. it must be done, fact of life i guess. So fellas, ballance the car out. rather then search for the impossible through front settings.

Ok a bit of an update on my issues.

My test track for this has been Rome in the extreme series in the European c/ship. My best time with my g27 was a 1.07.4 on sport soft tyres with a fully modified f430 Scuderia.

Now I just dusted off the cobwebs on my DFGT and had a crack in that. My best time was a 1.06.6. Almost a full second quicker and I only fiddled for half an hour.

So, is there anyone out there with both these wheels that can back up my testing? All my made up time was in the corner entries. I also did a quick fang of deep forest and I had a heap more oversteer than I do with my g27.

Edit: and beau is right about the diff. Locked diffs tend to drag thru the corners and produce understeer.

I think the real point is that one shoud first try drive around these apparent shotcomings before throwing radical surgical "fixes" at them.

Truely good drivers can make stock cars go fast ;)

I have spent years on the Corvette forums watching people (myslef included) buy shocks, wheels, tyres, gears etc to make our cars "go right".

Then along comes a factory engineer who just played a part-time test driver for GM (John Heinricy) and not only did he make the stock tyred and stock suspended and stock powered C5 Z06 do apparently impossible things on local US race tracks and for demonstration purposes, he piloted the 2004 Z16 Comm. Edition to a 7:56 Northloop lap, again on all stock setup. As in the car was totally setup within the parameters GM delivered the car to customers.

For trailbraking to work like it should ABS needs to be off, which is weird because weight transfer has nothing to do with rear tires locking. As soon as ABS is on it affects braking even if the tires do not lock. I can get good weight transfer when rear brakes are set to 0 with ABS off, but with ABS on, no deal. That is not right. :dunce:
 
Are the understeering folks using a control pad?
If you are then it will understeer because of the speed sensitive steering lock limits.

I'm finding the MR cars nice and neutral as they should be, with some on the oversteer side.
FR and 4WD cars will tend to understeer due to the weight of the engine at the front and the extra torque on the front wheels with 4WD ones
 
Overall, I think the physics feel pretty good in GT5. The only car I would question is the Veyron...but who knows. :)

As others have mentioned, I've noticed that none of the "stock" setups are what I would expect. As soon as I set the camber and toe to more reasonable values, the car instantly feels about how I would expect it to. After that, it's a matter of dialing in the springs, shocks, and sway bars to get the handling where I want under coasting conditions.

I say coasting, because the rear diff and torque split settings are critical in this game, especially on 4wd cars. So I usually go for a neutral (or slightly loose) handling setup while under very little power, and then work on the diff and torque split to get the same feel while powering into and out of corners.

BTW - I was able to get even the push-happy Veyron to turn pretty decently, and it can be tuned to be a drifting BEAST. :)
 
Agreed with OP, cars just don't snap-oversteer like they should, the physics seem to be very biased towards understeer. Although, full throttle drifting is awsome in this game,
 
Setup is key. I don't get why the devs didn't bother to enter some reasonable base setups for the cars... 0° of camber on almost every car? Makes no sense at all. Also i wonder why we can't change tyre pressure? Or why do we have to buy a suspension kit to change front camber and toe settings?

Setting up camber to optimum is a guessing game anyway without being able to read out tyre temperatures.
 
I've spent a night of online racing with my DFGT now and I'm certain it's faster than the G27. We were doing one make racing with the Calsonic Super GT skyline (which is EPIC on high speed ring with 16 identical cars and boost set at low) and the thing had chronic understeer with my G27. Tonight on my DFGT, it was perfectly balanced.

PD shenanigans?
