Well I after a lot of running with my BoxStock, I never could get it to run like I wanted. It handled well but just no power. I popped open the factory motor to clean and inspect, and while it was a bit dirty, the brushes and comm were good. So I brought out the parts bin, and changed it from a 98mm MM pod, to a 90mm RM pod, and I only have a Kyo Gear Diff so I slapped it in there ( basically Travelers MX-5 setup), and it ran well, but it had HUGE traction hop under acceleration and it made the back end squirrely and spin out in the corners. I tried all I could think of to get it to calm down, and the PN dual spring center shock, helped a lot, but I knew it could be better. So I swapped the Kyo RM pod for a Nexx 90/94mm RM pod. Both I ran a PN70T which ran tons better than the Kyo white endbell, so bad motor?
With the Nexx pod and PN 70T the wheel hop is almost gone. Also I had to go to N +1mm in the rear, as the W-1mm wheels wouldn't work as the wheel contacted the diff hub before it was anywhere near tight.

So for now I will be running Stock, ProStock, Porsche, Narrow, and MX-5. I may go back to BoxStock someday, but of now I enjoy the 90mm RM cars A LOT more than BoxStock. I also put my R8 2015 on my stock chassis and I like it more than the 12C. The R8 2015 does grab the walls a bit more than the 12C, but it the R8 turns better for me and I can get back to the power faster and my times are showing it! The front splitter is still factory length on the R8 (to be 100% legal for BoxStock) so that doesn't help with the wall grabbing, but I should just stay off the walls more!

Thanks for the thoughts on my health! I'm a bit better, but my spine is FUBAR, so my Pain Dr. tries his best to keep me going! But Yall keep me sane with this AWESOME Challenge! So A HUGE THANK YOU to all that keep this FUN challenge going, and for all the help yall provide!
