Anyone have experience with KAAZ 2-way diffs and using a lower final gear (3.5 to 3.7)? I'm running a ZF trans and dont like the high RPM at freeway speed. I'm not sure if the q45 3.54 gear bolts are too big for the diff or theres a correct size diff gear to run instead. I just need to know which final gear will fit so i can buy one.
Thanks for the help.
