[s-cars] Cracked Big Brake Brackets - ECS Stage 2

[Mark Strangways]

I have not seen ECS's stuff, I have seen bira's version.
It is well made radiused, threaded inserts etc.
It is a BLOCK of material, I do not see it under bending moments, or 
stresses that a "L" shaped bracket would be under.

Like I say, I have not seen ECS's bracket it may be the same as bira.
