this thread is unlike any other thread because it says why NOT to mod your g25. i recently modded my g25 (the stiffer shifter mod) and regret it HUGELY. the site recomended to cut spring about half, i cut it about a quarter, and filled the part i got rid of, with metal. it was un-realistically stiff, warranty void, have to be more careful, click louder, and my sequential doesn't work...i literally can't turn the knob. in the future i will probably mod the pedals so they are inverted, only because it is changing how they are placed, not how they work...feel free to comment.
