    Is this firewall flex something I should worry about?

    Ok so I got my mustang Steve pedal assembly and clutch cable setup installed.  While testing it out I noticed the firewall flexing really bad. Is this something I should be concerned about or reinforce in some way beyond the thick plate on the pedal assembly that mates up to the firewall?

    Copy and paste the full link into a new browser window. The hyperlink it created won't work if you just click on it.

    Firewall flexing at the actual booster assembly mount location, not the firewall adjuster area.  He has the reinforcement plate pedal assembly too

    The flange bracket in the PB-2 kit is designed to reinforce the area you are concerned about.  If you bought your pedal assembly recently it should have the flange bracket already installed. That may be what you are referring to. How much flex are you experiencing?

    I purchased the kit CK165-M, which comes with the firewall brace you speak of.

    The link I posted got messed up but if you copy and paste the whole string of text from my original post into a browser, it should play. The whole firewall and brakebooster flex back and forth when I press the clutch pedal down and release.

    Back up for Steve. The entire firewall moves from middle of car all the way left. Rust free Virgin car. Moving right where booster and pedal assembly is bolted, and flexes entire firewall

    Steve is moving Wednesday and Thursday. It will probably be a couple of days before he checks in on the forum.

    This is a really stupid question butt (TS&T) I gotta ask...do you have the pedal hanger bolted tightly to the dash?

    Yep, pedal assembly is bolted down tightly against the firewall and where it mounts to the dash.

    Re: Is this firewall flex something I should worry about?

    Movement is typical even with stock clutch linkage due to the force applied at the pedal. You now have additional bracing to help spread the load. Nothing to worry about.
    Be sure the aluminum block is tight against the firewall.

    Nobody ever sees the stock firewall and clutch pedal flexing because they are inside the car!

    Money you enjoy wasting is NOT wasted money... unless your wife finds out.
