I received my G25 last night and was able to try it out for about three hours using LFS. I know a lot of people are eagerly awaiting this wheel so I figured I'd post my initial impressions after a night of heavy use.
The first thing that gives you an impression is that the box seems smaller than you'd think and is a lot heavier than you'd think. Even though there's a third pedal and a shifter in there, it's not much bigger than the DFP box. My listed shipping weight was over 20lbs, so it's no lightweight either.
After unpacking the box and hooking everything up I came to a few conclusions. They made a very good decision by having the cables all plug in to a recessed portion of the wheel. No more problems with the power cord disconnecting in the middle of a race. Unfortunately, they also made a mistake with the wiring in that the wire to connect the pedals to the wheel is much too short. I should have measured the actual length before writing this review, but suffice it to say that the cord is barely long enough to reach and it quite often ends up in the way of my right foot when driving. I'm most likely going to have to make an extension cable using radio shack parts. This mistake is almost unforgiveable to me.
I uninstalled the old Wingman software and installed the new v.5 that comes with the G25. I left the Wingman software at 100% forces, but turned off the "extra" unnecessary forces and unchecked "combined pedals" (God only knows why this is checked as default). I plugged in the wheel and made sure it worked in the control panel applet, then opened LFS and set it up in game. Setup was quite easy. The throttle, brake, and clutch were setup correctly out of the box (I was using a DFP before, so this is probably why). I just had to configure the shifter and other buttons since they do not correspond to the ones on the DFP which I was using before. Make sure that when you try to setup LFS you choose "shifter" in the options. If you currently have a wheel you most likely have "sequential" selected.
Once I had a chance to use it in game I came away with several impressions of the device. First and foremost, this wheel is far and away better than the DFP. The circumference of the wheel itself is so much larger that it feels much more real in your hands. The wheel itself has less girth than the DFP which also makes it feel more realistic and less like a playstation controller. In addition, the leather on the wheel is very comfortable and looks great. However; after long driving sessions you may find that the stitching rubs your thumbs a bit raw. The wheel itself feels much more solid than the one on the DFP with less "play" in the steering and an overall heftier feel. Not to mention that the force feedback is superb. This is, bar none, the best force feedback wheel I've ever used and I prefer it to my friend's ECCI non-FF wheel. The forces are smooth and consistent and there's no "notchy" feeling that you get when you turn the DFP more than 90* or so. There's much less gear noise than you get with the DFP, but that's not to say the wheel is silent. The FF still generates noise which reverberates through your desk (or, at least, my desk). So, while it is quieter, don't expect it to be whisper quiet like an arcade machine driving wheel.
The pedals look and feel very nice. The metal finish adds a lot to the presentation and the base of the pedals is very hefty and sturdy. I get the impression that these pedals will last much longer and take much more abuse than anything else out there, save for the high-end stuff companies like ECCI and BRD make. The pedals are much stiffer than the previous stuff that logitech has released. The brake pedal in particular has a very satisfying heavy resistance which should make it easier to prevent locking up the brakes unintentionally. I do have a complaint about the pedals though. The gas and brake are too far apart, and the clutch and brake are too close together. I'm not sure who designed this, but they've got their dimensions all wrong. Because I now have a complete setup (clutch and H-shifter) I turned off all the aids in LFS. No more auto clutch, no more auto blip. With these aids off it is necessary to heel-toe the throttle and brake to get smooth downshifts. Doing this on the G25s pedals is difficult at best. Doing it without shoes on, which is the way I normally drive sims, can be downright painful. I have full intentions of removing the pedal pads and moving them so that the gas and brake are closer together. In addition, I may end up having to drive with shoes on because the edges of the pedals can be somewhat sharp and painful after a few hours of use. In fact, a friend of mine who also got his G25 had to finally stop driving last night because his feet hurt so badly. YMMV, of course.
Now, on to the shifter. The H-shifter included with this wheel was the thing I was most looking forward to and, it figures, the thing I'm most disappointed with. It's a nice looking unit which mounts very solidly to the desk. Unfortunately, the way in which it mounts places it very high and far away. The shift lever itself ends up at about the same height as the one on the DFP. Not a problem in sequential mode, but it can be difficult to handle in H-mode. The majority of the buttons for the G25 are on the shifter base and they are placed behind the shift lever itself (furthest away from you). This makes reaching the top buttons and hat a stretch, and makes hitting the bottom buttons difficult because they're blocked by the shifter. Also, the shifter itself leaves a lot to be desired. Gear engagements make a satisfying click, but the lever is so short, the gates are so close, and the springs are soft enough that mis-shifts were common for me. I definitely think that the shifter would benefit from being an inch or two longer and having a much heavier spring. I lost count of the number of times I downshifted from 5th to 2nd last night. Perhaps this would be less of an issue if the shifter were mounted lower in a more natural position, but without building a custom mounting spot I won't be able to test this theory. I think that the shifter assembly would have been a much better unit if it a) mounted lower b) had a longer shift lever c) had stiffer springs and d) had the buttons mounted behind the shifter instead of in front of it (closer to the driver).
All in all, the G25 is a huge improvement over the DFP. The wheel itself is far and away better and really can't even be compared other than the fact that they're made by the same company and both support 900* rotation. However; I feel that the shifter and pedals leave a lot to be desired. I had high hopes for this piece of equipment and now will end up disassembling much of it to see if I can fix the things that I'm not pleased with. This is of course all personal opinion based on my own experiece (and that of a friend) and you may have a different experience. But I do think that I've given a fair and honest review. If anyone has any questions about the wheel or accessories I'd be happy to try to answer them.
