Breaking rear shock towers - likely suspect?

Tell him to be careful, I spent thousands on my Tmaxx and it seemed like the more I changed to worse the truck handled. I think back to when I first started bashing I could get that thing to grab some serious hang time, after all was said and done it was too heavy and it got sold. I even swapped in a picco .26maxx. It just wasnt nearly as fun even though I broke stuff everytime I went out when it was stock. Either that or the novelty wore off from chasing tunes.
I am now building a HCR Mutant Maxx BL it will be a lot more fun
