IMO, OHH Yeah! The G25/27 Wheel (and defently also the pedals) is just so much better than the DFGT.
Im a bit fan of drift, and was such at B.I.AT.CH to learn on DFGT, actually i couldnt do it after 2 weeks off practicing. Then ive tryed my friends G27, and it was spot on! Manage to get gold in Seasonal Drift event at secound try (even with out setting the car up for it). The response of the G´series Wheel is perfect, and pedals are a real treat compared to DFGT´s. Gear shifts are also really nice. I Bought the T500Rs after wathing too many vids and reviews and specs. When i got it, i was quite unhappy with it in GT5, but was amazed on Pc sims. Its actually only in GT5 my complants are.
The Logitech G´series wheel will absolutly give you what you need in GT5 and on Pc´s. And if you only play GT5, Ive save the Money and get a G´series 👍
DFGT was good in GT4 ´days, but it will be a new World upgrading!
