Blitz questions

[Firestarter0]

does anybody have any recommendations to help me solve my blitz issues?

servo slop- basically i need a new servo. my ansmann one isnt waterproof since i had to take the back off to make it fit, and it has pretty bad slop in it. the arm will turn basically a full point of the teeth that grip the arm.

steering- i know this is a known problem with blitz. i have the strc rack which helped, hence my need for metal gear servo (stripped gears in two plastic ones, even with servo saver loosened). i played with front toe, different holes on the rack etc. its not helped much yet.

brakes- (i have the firestorm flux vector motor and vapor esc) brakes dont do anything. could i help this with the esc programming card?

thats pretty much it i think. any ideas?
