It's hard to describe but DFGt has standard gears while G27 has helical. Helical gears has less resistance to movement especially fast movement while standard gears put up more resistance the faster you try to spin the wheel (especially when turning against the ffb). G27 helical gears even has less resistance than Fanatec GT2/3 belt.
The down side of using helical gears is it adds pressure along the motor's shaft. If the motor is rapidly engaging and disengaging (simulating dirt) it will cause the motor shaft hit the plastic stopper which makes some noise.
As far as ffb motors strength ; My DFGT ffb is either very weak or very strong while G27 has better range from weak to strong. In GT5 DFGT seem to tired out my arms more than G27 in long races.

We have both and honestly the difference is pretty small. But, the DFGT is a little louder--you hear the gears (or whatever) pretty clear when turning the wheel sharply.
Also, because we have both, I've noticed the difference in the feel of the pedals. The G27 pedals have better feel (resistance?). But, if I didn't have both wheels I wouldn't know the difference and it probably wouldn't bother me to just use the DFGT.

The reason I'm asking is because I own a DFGT, but want an H shifter.
I didn't like in rFactor how the steering was so light, with so little resistance.
I read somewhere that the G27 has lesser resistance, which would be one of the few reasons that I wouldn't buy it.
But if it isn't that much of a difference, I might just go for it...

Normal gear:
G27 Helical Gear:
It gives smoother and wider feelings.
Anyway, I changed my DFGT to G27 and regretted. G27 has better shift paddles and pedals, but totally lack controls and adjustments, like abs/tc through the ring button. You need to set it before going into race and done. In a endurance race that you might need to change, you can't.
And you miss somethings like the horn, lights, wipers...
If you love GT5, keep the DFGT!

I own a g27 and velcro'd a controller to the center of my steering wheel. I can set more buttons than any other wheel now. Simple fix and fits nicely!

Although the lack of fully programmable buttons on the G27 stinks, you can still access the driver aid menu by programming it to a controller. I use the select button to bring it up and the D-Pad up and down to scroll through the items and left and right on the D-Pad to change the values.

False. This only works on the G25, there is no way to map the buttons on the wheel of a G27. You get "Look Behind" (top left button) and "Hi beams/Low beams" (top right button). But honestly, I don't even notice it. The only buttons missing are the windshield wipers (they turn on automatically if you need them so there's no point in having a button for them) and the horn (it's only good for annoying other drivers so there's really no need for that either).
Same with the "quick-change" dial selector, I set all that stuff before I enter the course and have never had the need to change it during a race, so no loss there. I use to change the settings mid-race when I had a DFGT but it usually did more harm than good because it distracted me. It's really apples to oranges though, the smoothness and quietness of the G27 increases the quality of the experience so much that not much else matters. I soooooo LOVE not hearing those gears grinding when I'm turning the wheel! But back to the OP, the only difference in resistance between the 2 wheels is that the G27 is so much smoother because of the different gears.

Is that factual? Mine seems to be adjustable.
To the OP: G27 and DFGT are virtually awash. I liked the buttons on the DFGT much better, I like the paddles and pedals on the G27, and I think its quieter, I doubt that is smoother except maybe to the experienced and therefore picky sim racers. I saw GT academy guys stating that the DFGT was their weapon of choice, so obviously it won't make you any faster to buy the more spendy G27.
BTW, the clutch and shifter suck. If thats what ur after step up to fanatec or maybe the TM500000000$$$

I guess it's anecdotal, it's been widely reported on this board that the FFB adjustability only works on the G25. I have tried different settings myself and notice no difference. I don't have any hard data to back it up though. As for being smoother, I believe the helical gears do make it smoother. I could feel the gears grinding in my DFGT, I never feel that in my G27. Again, just my experience.
The pedals on the G27 are far superior to the DFGT pedals, they're almost worth the increased cost by themselves. I've never had any problem with the clutch or the shifter but I've never used a higher-end wheel so I don't know what the "better" ones feel like.

Hmmm, I might have to check when I get home.
Regarding the G27 controls. My shifter blows, maybe I got a bad one, it rarely recognizes 2nd gear unless I shift like a nanny, no fast movement. Clutch is fine, but most contests ban the use because of the glitch or something.

I think most of us have the same issues with the 2nd gear. We had a discussion about this before in this one thread, and everyone seems to agree that you can't change gears while your in full throttle, which some argue that they drive like that in real life. So check it out next time. Remember, don't make a habit of having your hand sit on the shifter like in real life
, it does wonders when on the G27. Do that and you'll never be stuck in neutral. I still sometimes do when I get over excited when I'm on a heat of a moment.- 581

I'm a bit confused with this post and your previous one regarding FFB. Did you mean it the settings does not work on G25 or G27? On your previous post you stated that it does not work on G27, but on this one it does?
I have a G27 and my ffb settings works.

I've experienced that a handful of times, but no more than I do in my real car. I've managed to train myself to not do it I guess because it hasn't happened in quite a while. You don't have to be fully off the throttle when you shift, but there is a balance required that takes a little practice.

I own a G25 and DFGT, and tried both of them recently in GT5 to remind myself of how they differ (usually I use the G25 only on the PC, the DFGT on the PS3).
The "power steering" setting in GT5 is absolutely essential on the DFGT, it allows you to spin the wheel with apparently less resistance from the motor, thereby allowing you to make a sharp fast turn of the wheel quicker (I suppose it probably detects your movement and adds the motor in the same direction to help you spin the wheel faster or something sneaky like that?). My G25 has never got in the way when I want to spin the wheel fast, so you don't need that setting. You can easily feel this difference by spinning the DFGT versus the G25 when they are both unplugged.
In terms of FFB I came to the conclusion that GT5 itself is tuned for DFGT feedback, and the G25 probably just inherently uses this same setting. And in my opinion that's the key reason why the G25 doesn't offer more subtlety within the game, it's being held back....
In PC sims, where you can configure Logitech Profiler optimally for each wheel, the G25 FFB shines as being far more powerful but also more subtle than the DFGT - you feel smaller bumps on the road, more variation in feel of grip loss, etc.... Another example: I've played through DiRT 2 completely on both PS3 and PC, and I found the PC FFB through the G25 way better than the PS3 FFB through the DFGT, to the extent of me being able to set faster times and feel the road better.
But it's not all "G25 better": There is also a difference in favour of the DFGT. The DFGT has one motor which works at any wheel orientation, but there is a known deadzone in the middle of the G25 where the two motors meet, and this is very noticeable on sims which don't explicitly compensate for it (iRacing for instance compensates for the G25 deadzone very effectively, you mostly forget that it's there, rFactor doesn't).
And of course the pedals and paddles are vastly better on the G25, but the DFGT compensates by having all buttons (including the PS button) on wheel.
Since GT5 doesn't punish you for being heavy with the brake pedal, doesn't really offer any FFB benefit from owning a G25, and having the buttons on the wheel is a big plus, I choose to use my DFGT with GT5.

I'll confess it is a long pause, and like they say, clutch all the way in, gas all the way off or you are in neutral. I presume ( definitely speculative) there are probably limited input addresses in a playstation system, and while the wheel sensitivity and accuracy are extremely impressive on the G27, the clutch/stick isn't even close to real, (which would require a resistance motor since real clutch engagement can be felt thru the pedal) so I just use it when I want to pretend I'm driving an old school beetle or vette, which are slow anyways.
