Welcome aboard!
You can Bash anything and anything can and will break, given the proper beating.
You ought to consider a steering servo and servo saver upgrade right off the bat. The vehicles handling will improve dramatically.
For the arms UE offers three different suspension systems. The best UE set for bashing is the
Supermaxx EXT
Turn buckles I'd go UE. For a screw set stay away from aluminum, stainless and titanium. I feel that high grade steel caphead screws should be used wherever you can. You could buy in quantity from a place like
McMasters or ride specific set from
Tony's Screws.
I am not familiar with coolbillet but your description cheap billett is probably accurate.
