Why does HR not recommend bolt-on rear shock-tower braces?
Our design team finds that the shock towers and trunk floor do not offer the proper surface for bolt fasteners to be of any use. Drilling the required holes for the fastening hardware also weakens the shock towers. Additionally, bolt-on RSTB’s cannot provide the rigidity required for its intended purpose—stiffening and strengthening the rear shock towers in tandem with providing a load path for lateral energy transfer.
