fab a rear strut tower brace soon
good news! honda already did it! its called the rear deck. if you notice, the very tops of the strut towers are attached to it. the better thing to do would be to make a brace for that giant hole that goes from the cabin into the trunk.

Combining that with the roll bar, front lower 4point brace, TL front tower brace, rear lower tie bar, and 07-08 TL-S rear sway bar (which I'm picking up on Monday
)..... its gonna be stiffer than a fricken tree.
