I tried 2 different G25s, the first one I had, the brake pedal was really stiff, and I absolutely loved it! I could control skidding so much better and just felt so much better. But then the wheel broke (made that really dreadful mechanical grinding noise as found in the noisy G25 thread), and I got a new wheel. The pedals in my second one are really weak... maybe just a tad stiffer than my momo wheels and that was a real dissapointment. (and its also starting to make that grinding noise again, although its not as loud... yet)
I'm surprised there was such a a lack of consistency in the pedals, was certainly expecting a much higher standard of quality from this product.
