Thats the only nessecary aluminum part besides the motor plate obviously. I don't even run that aluminum brace on my T4 and I've had zero issues with it. My B4 was a FT though, so I don't know how well the plastic one holds up on the buggy, my guess is it would be pretty good. You might be able to get the Ti turnbuckles done in green as well. An green aluminum battery strap would be cool too!
