I was using whatever the 1/8" steel stock that was available at lowes. I started to use titium in hopes that it would be a bit harder and a bit lighter. So far, even though it may not be top of the line titanium mix, it does seem to be holding up well. I'll know more as time goes on. I only used it on the stampede though, which is my lightest vehicle, but it had the same issue with getting the front/rear all ground down from my skate park. Now it makes bright sparks when it makes contact... probably a fire hazard now. lol!Is there a reason why you've stopped using titanium?
Might give it a try as my Talion's butt is always dragging.
They have 2.5mm*10cm and might get a couple out of those.
