be that as it may, you can't just add cars into a game without a car manufacturer knowing, and allowing you to do such. imagine making a game, putting licensed (ie:copyrighted) content in it, and then getting sued by all the auto manufacturers. that's why the cars in LFS are fictional, with the exception of the MRT, RAC, FBM and BF1. (am i forgetting any?)
i don't know about the g27, but the g25 isn't that noisy if you treat it properly... if you stomp on the gas, it hits a backstop that makes a thunk sound... and if you shift too hard it makes loud clicking noises.
i think most people are just too rough with their stuff.
