I ordered the same tire and rim combo Jerry... Nice Moab clone... When I mounted them up, the spokes rubbed on my EXT knuckles... Gonna have to do some trimming of the rims to run on my truck... But they do look good!
I have a set of those extenders in one of my parts boxes that I can use with them. I think they are long enough to increase the wheel to wheel distance by 1 1/2" to 2". That should be enough to keep the wheel from rubbing.
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.
