I ran mine with a 19t modified motor and it held like a champ.
Don't worry about shock tower and the narrowed bulkhead, they will hold for sure, I did the same exact thing for my VONATs Bearhawk, and it held strong through out 4 qualifiers and a very competitive A-main.

On my project, I used a T3 Bulkhead and the Bullet arms and it gave me that nice front width.
I'm kind of sad that I sold mine...
