Not something I would suggest, but I hope it works for you.
why would you not suggest it?...granted the rears aren't necessary but to stop the upper front arms snapping and bending all the time they're needed at the front ... in my experience.
hopefully you should get some time out of it now...close to the spec mine was when I finally managed to get 5 tanks without a single thing going wrong...as long as the diff cups have been sorted, (and seems they have been though I've not tried them yet) the only thing i foresee is a broken dogbone pin...that's what gave up after the 5 tank record run
