They didn't rub enough to warrant the extra width... As heavy as they are there's enough stress on the bearings already... A quick shot with the dremel and a sanding drum will take care of it... Just a few mm''s needs to be taken off... A small few...
I was so happy getting my HPI box that I went in and ordered a few more items seeing that most everything was $1. Kind of like going into the dollar store. I spent another $100 on spare drive shafts and gears. I wanted a good selection of center drive shafts to choose from for different build projects, since RCAlloys is out of the picture now. I hate having to wait on custom drive shafts being made for specific build requirements. For a $1 you can't beat the price. Plus I like having a good stock of spare parts to draw from.
Well I received my second box of HPI goodies today. Two more center diffs 50T, and one regular diff $9 each, plus a whole bunch of other stuff. God bless America.
