That's a lot of work to get done in a minute 38"thumbsup"
Looking good man. Any chance you can crawl Coyote this weekend?
Have you considered ar60s? I dont think you will ever get the most crisp steering with those wideners. I also think the added width would help with crawling performance and overall rig balance.
I have the XR10 mod on scx axles for my 1/10 scaler and the width is 9.5" outside to outside of the tires.
The AR60 axles are better suited for these Jeeps, o/o measures 11.5".
So, just to let you know, the XR mod won't give you what you want. "thumbsup"
My axles are 1" wider than SCX10 axles and 1" narrower than AR60's and they work well.
I think, if you do the XR mod using wider beef toobs, the width comes out just about right.
