Everywhere I look, they only have front tower bars for the 3rd generation. Where can I find a rear tower bar?
The 3rd generation Protegé 4 door has the rear strut towers already braced; it is actually part of the unibody. It is quite big and should offer lots of reinforcement. The Protegé 5 does not have the rear brace as part of the unibody due to its hatchback configuration. Unfortunately there is not a known aftermarket company in the US that makes a rear bar. Talk to an aftermarket company to consider making one. The only known solution for the Protegé 5 at the moment, is importing the AutoExe or Okuyama rear tower bar.
