Thanks a bunch, do you have any tips with dirt3, i was able to get plugin working with f1 2014, but not dirt3. I am not sure if it is related with my outdated dirt3 version. I will try updating it but just want to know if you have some difficulty setting up dirt3 with ian bff.

Hi Stevant,

Just checking in, Great Idea using the butt kickers I would think they bring it to a whole new level!
And I am sure you know already but on the off chance that you don't Dirt Rally I think you might like it see below for my bad driving   

Hi Stevant !
Merry Christmas also ! ;-)
Thanks for sharing and full agree with you !
I have to modify also my mounting for my 6dof joints .I push them to their limits angle and I know that it's a focusing mechanical point!
Grease solves the noise problem but not the wear !

Also, DiRT3 is my favorite racing game by far and I can't hardly wait to try DiRT Rally! My focus is mostly flight (and especially Star Citizen) but I plan to put a good number of miles on my 6DOF rig playing in the DiRT!

Merry Christmas and Happy Holidays to all!
