Paddle shifters on the G25 do work in GT5P, you just have to switch the shifter into sequential mode.
I am a G25 owner and a happy one at that, but I 'm leaning towards an upgrade and getting the G27.
For all you previous G25 owners that are now G27 owners, can you tell me if it is worth the upgrade or not?
or should I just stick with my G25?
I think its money better spent giving a better upgrade as G27 wont really give you a major upgrade except the quieter gearing and the lights.
