Hi everyone. So my transmission is starting to fail me. I've decided that while rebuilding my transmission I will just swap my final drive with the mfactory r18 final drive. I've searched and although I've heard about people talking about it. I haven't heard of anyone who's done this or seen any videos of the results. Has anyone put this in their car who's running a N/A, T/C, or S/C build? Also, right now my car is pretty much stock. Any idea of the gains I could expect from this?
