Front wishbone breakage

[Dadio]

As the title say's I'm having front wishbone breakage problems ,I've broken 3 now ,1 was richly deserved ,the second was a fair hit but supprising it broke but the 3'rd today was really supprising ,my friend (driving my car ) T boned his RB6 ,my front wheel hitting his rear ,this was on sand and not that fast and it tore the front wishbone off and broke the plastic top mounting insert into the metal shock screw cap ,luckily i found the plastic part for the shock sold separatly.
So my question is ,is there much difference in strength in the dearer comp arms or is there a stronger other option ?
I measured up the RB6 arms and with a little work they could fit ,I've ordered up the comp option arms for now but I think I did before however I'm not sure wich car i put them on my TR02V2 or my TC02C ,I need to start making notes on what's fitted to what I guess .
