    Installed was easy enough in theory. My big hands got in the way along with not wanting to do extra work removing pieces around it. Eventually I got it in. Another high quality Cusco part. Brake pedal response feels better but without any scientific testing, I can't tell you if it actually made a huge difference or not. If nothing else its some nice Cusco blue to add down in the depths of the hood.

    Installed on my 02 wrx wagon, greatly increased pedal feel and stiffness. At 160k miles my brake pedal felt soft and had to push almost half way in just to start rubbing the brakes. With this the pedal is almost instantly applying brakes. Probably the best improvement item i have installed. Recommend to anyone looking to get better feel from their brake pedal. Excellent product.

    Not sure I notice much of a braking difference. Looks cool in the engine bay nonetheless. Pain to install.

    • Q: Fitment  A17Attacker715009 years ago

      Will this fit onto a 2001 2.5RS?
      • 0 of 0 people found the following answer helpful

        A:  Cusco only confirms fitment with this part for 2002-2007 models and I don't believe it will mount properly on your 2001 model.

    • Q: Fuel filter  actalone_bassist9 years ago

      Would I have to relocate the fuel filter or get an aftermarket fuel filter when installing this item?
    • Q: Will Cusco Brake Cylinder Stopper Subaru Impreza (inc. WRX / STI) fit a Legacy GT?  05LGT11 years ago

      Will this master cylinder brace fit on a 2005 Legacy GT? According to this write up on the LGT forum, it will: http://legacygt.com/forums/showthread.php/cusco-master-cylinder-bracket-installed-80021.html The photos shown in this thread are clearly from an LGT. I've confirmed the position of the vacuum hoses and fuel lines. There's enough play in them to remove their brackets and install the Cusco brace. The holes on the cylinder brace look like they'll line up exactly with existing holes in the strut tower. Do you have any information to back up the claim made on the LGT forum? Thanks!
      • 0 of 0 people found the following answer helpful

        A:  Short answer, no. Cusco lists the fitment as the GD Impreza and not the LGT. The poster in said thread that actually installed it even said he thinks it was for a JDM car (see post 9). So this would be an at your own risk type of deal. If you get the brace and before opening it you decide it will not work, we can take it back. But once it is opened, we can not accept a return on it. You can view our return policy here at http://www.rallysportdirect.com/policies_returns.cfm . Thank you.
