Crystal ball

I just installed a quark 125 - 9xl - 14 cell into my emaxx.
WOW:004: , It flips over on itself on slick concrete and nearly blows the tires off of the rims during power spins "if you can keep it on it's top."
My question is what is going to break next??
I installed upgraded cvds, aliminum frame braces,arms, bulk heads, shock towers. "I broke all of this stuff with the titans"
Are the diffs next? If so what is the best way to upgrade??
I'd like to slowly upgrade before i break. Slowly because I'm on a budget.
