I've seen a bunch of G25 threads where you can't get the car into reverse gear at all, this is a different problem though.

When I put ANY car in reverse, the wheel seems to pull the wrong direction and the FFB gets extremely heavy. When I shift back to a forward gear everything is fine again. I've been experiencing this problem ever since I got the wheel but just ignored it because I'm not actually in reverse all that much. Has anyone else had this problem? Am I just missing some setting I should enable? Maybe this is how its supposed to be and I'm just imagining things, but it definitely doesn't feel right. Also, I have the wheel all set up according to the wheel guide in the LFS manual.

That just sounds like LFS to me. Had that with my G25 and my momo.

That's the effect of positive caster for you

yeah that affect is real, i like if for doing j turns
