    Review & Installation Video

    What’s up everyone, Justin from, here with a cure to that mushy clutch pedal, and that sticky clutch cable on your ride. I’m talking about this adjustable clutch kit for all 96-04 Mustangs. Simply put, this kit is going to make your car shift like new again by replacing and reinforcing some of the crucial components responsible for getting your car into gear properly and smoothly. The first and most obvious part of this kit is the brand new fully adjustable clutch cable which replaces your old gummed up factory cable. Now over time your clutch cable picks up all kinds of dirt and grime, making for inconsistent pedal feel. As you can see this new cable slides easily, and without any effort whatsoever, and when paired with other kit components, makes for a smooth pedal feel and full adjustability. The adjustability I’m talking about is made possible thanks to this firewall adjuster. This part makes life a whole lot easier when it comes to adjusting your clutch, thanks to the fact that you don’t have to crawl under your car anymore to do so. The new clutch cable will run through this piece mounted on your firewall and simply by turning this knob you can adjust the length of your clutch cable. Now this will also give you much more precise control over your clutch pedal engagement point to better suit your style of driving. The star of this kit without a doubt is the Billet aluminum double hook clutch quadrant. Your clutch cable runs through this little piece bearing the brunt of all those hard shifts. Now your stock quadrant is made from cheap plastic which can flex or even break causing mis-shifts especially when using heavier duty clutches and pressure plates. This Billet aluminum piece totally eliminates the cheap plastic, and is designed to hold up to even the hardest shifts. Installing this kit requires you to remove your factory clutch quadrant and cable, although it’s nothing more complicated than removing a few bolts and snaking some cables, you do have to crawl underneath your car making it somewhat of a time consuming install that should take you a couple of hours. Now we here at AmericanMuscle always recommend installing this kit especially when using aftermarket clutches. It’s a simple peace of mind that will make your life a whole lot easier, trust me. If you’re experiencing a mushy clutch pedal, mis-shifts or an overall poor shifting experience, then this clutch adjuster kit for your 96-04 Mustang will have your car shifting like new all over again.

    Easily Adjustable. Looking for an easy way to adjust your clutch? This firewall mounted SR Performance clutch adjuster lets you adjust clutch engagement without having to crawl under the car. Just turn the adjuster knob on the firewall and you're done.

    Spring Loaded. The new internal spring loaded set-screw keeps the cable securely in place with no need for re-adjustment. Just set it once and forget it.

    Features. This SR Performance firewall cable adjuster bigger adjustment range than the other guy's, plus a handy locking tab so you can adjust it with just one hand, and it has a bright polished finish.

    Application. Fits 1979-2004 Mustangs

    Technical Note. This Firewall Cable Adjuster works with the factory cable, but requires the use of an after-market solid quadrant, it cannot be used with factory quadrant.

    Is the double hook quadrant required? Is the double hook quadrant required, or will this product work with the Steeda quick release clutch quadrant?


    • This firewall adjuster is actually required if you wanted to use the Steeda Quick Release Quadrant. You could use either of those quadrants with this firewall adjustor though. Only thing to keep in mind is if you go with the double hook quadrant, that requires an adjustable clutch cable as well.

    Would I able to combine this with the maximum motorsport clutch quadrant and Ford adjustable clutch cable?


    Will this part be compatible with a fully stock clutch system? My cable is stock, my quadrant is stock (pretty much everything is stock). I get a tweeting sound coming from my throw out bearing when my clutch pedal is fully released, and this should fix my problem. I just want to know if this part will be compatible with a stock cable, or if I have to buy an aftermarket cable and quadrant.


    • The SR Performance Firewall Cable Adjuster works with the factory cable, but requires the use of an after-market solid quadrant. It will not work with your factory quadrant.

      Works great on my 03 Cobra

      I love this part. Fixed my shifting problems. And I use the stock clutch cable (but you have to modify it) along with aftermarket quadrant. This part is so easy to adjust and stays in place when set. Getting one for my 03 Mach 1 as well.

      It was ok

      Had problems putting the adjuster in my firewall. Needed to have it in asap so I wound up sanding the part so it would fit in the firewall. Kinda hard to get to the lock screw but it does it's job. It's not the best unit, but it's priced very well, so can't complain too much. Super fast shipping as always.

      Quadrant and firewall adjuster

      The product itself is nicely maid. Unfortunately it does not fit a 79 mustang. The pedal assembly does not work with it we had to fabricate a bracket to mount it to the pedal assembly. Also the firewall adjuster doesn't fit we had to drill it out 1/2" bigger to make it fit. Like the actual product but it doesn't fit the 79 mustang as advertised.

      Does what it needs to

      Shipping amazing as always, feels well built so no worries, I used my stock cable which is new and a steeda quadrant which all worked. I couldn't find an answer if it would or not. The only thing is my cable didn't fit I had to cut a piece out, if you have a stock cable it's the piece that doesn't come off. But it WILL still work perfectly. AND the stock bolts are NOT long enough so I improvised and got longer ones, it does work flawlessly and have a locking Allen bolt on the side. All in all I'm glad I got it. Saved my throwout bearing

      firewall clutch ajuster

      This product was much better than the BBK firewall adjuster I got. Having the 2 ears to affix to the firewall is almost mandatory where the BBK model does not.

      Works but with difficulty

      Was fairly disappointed in this product. Mine did not include the screws and the mounting holes did not line up correctly. I made it work but it shouldn't have been that hard.

      Very easy to install, the Allen key to lock it in place is in a bad place and can only get 1/4 turns as you hit the firewall.

      clutch feels much better

      Installed along with maximum motorsports clutch cable, and quadrant. The trio works perfectly and was easy to install and adjust! The only problem i had was that the 2 screws that came with the adjuster were not long enough (neither were the stock screws), so i had to use some of my own.

      Clutch quadrant quality

      Quandrant is excellent quality and looks very nice. Definitely easy to use when needing to adjust and works very well with adjustable cable when installed. I would definitely recommend this product to anybody who doesn't want to spend to much on a quandrant but wants a top gun quality part that will perform as well as the more expensive quandrants. The only advice I have to give to SR performance is to create a wrench like tool to easily turn the knob without hurting your fingers that way you can make adjustments without stressing your fingers, other than that keep up the great work SRperformance.
