recommended 210 upgrades and mods

[johnnygibbon]

allthough there is good set up advice and pics of upgrades ect i wanted to start a thread to see what was the most poular upgrades and or recommended mods for the 210 and what weak points it may have
the main parts i think may need upgrading are

.front hubs/spindles - saw one break of a crash on some doubles
.shock towers - look strong but carbon towers seem poular
.rear hubs - do they hold up well or is alloy the way forward
.gear diff or ball diff - most people seem to be running ball
.extra weight - is it neccesary and where should it go
.what front tyres - for outdoor astro as a good starting point
i will be running yellow mini spikes on the rear but unsure what front to use .. thinking staggers or slim spikes .. am i right ?

i no these cars are pretty damm tough generally but i would like to make mine a little more bomb proof so its got a better chance of surviving my 2wd efforts
but dont want to spend a fortune on uneccesary upgrades cos these cars seem to run dam well as standard but any little mods or tips that help are well appreciated

i will be running big 5200 lipo stick packs and full size servo in mine so i dont no if extra weight will be needed

thanks in advance
