Out with the old…

…and in with the new. Steeda’s double-hook billet aluminum clutch quadrant, firewall adjuster, and adjustable cable may just be the ultimate in clutch adjustability, making it more convenient to adjust the clutch to your liking.

This cover on the driver side of the transmission must be removed. Behind it you’ll find where the cable is attached to the clutch fork. Use a pry bar to slacken the cable and disconnect it from the clutch fork.

Due to underdash space limitations we’re unable to show you how to remove the factory quadrant, however, we can tell how it’s removed. First of all, it’s attached to the top of the clutch pedal (No, really!) under the dash. There are little clips that hold each component in place. Don’t throw these clips away as you will reuse them. Press the clutch pedal to the floor and pry the plastic quadrant and clutch pawl out. With the factory quadrant removed, take out the stock cable. Now install Steeda’s billet quadrant.

With the clutch cable disconnected from the clutch fork and factory quadrant, the last step in the removal process is to loosen it from the driver-side framerail where it is held in place. Steeda’s adjustable cable is attached in the same place as the stock cable on Fox Mustangs. However, with SN-95 Mustangs, the Steeda cable is routed in a different manner.

When using Steeda’s firewall adjuster, the firewall bushing must be removed from the cable. Furthermore, there are four small bumps on the end of the clutch cable that need to be filed off in order to install the cable into the firewall adjuster. Connect the cable to the Steeda billet quadrant and clutch fork before any adjusting is done.

Attach the cable to the clutch fork and adjust it fully. With the firewall adjuster in place we can do all the adjusting from there without having to crawl under the car again.

Reinstall the cover and adjust the clutch cable to your liking using the firewall adjuster. Have a buddy adjust it while you’re in the car and you’ll be ready to go. We visited Steeda’s Pompano Beach, Florida, headquarters for the install, which took roughly an hour. However, this is not a terribly difficult upgrade and could be done at home with common tools, although a lift would save time and make it much easier when working under the car.

In between adding an intake, nitrous, and exhaust components, it seems that nary a thought is given to replacing the factory clutch-cable arrangement. That is, until the cable breaks or wears out. Then it seems like a good idea to replace it with one of the performance variety.

Since performance mods are growing on our '93 coupe, we thought now would be a good time to bolster our clutch-cable setup with Steeda's billet clutch quadrant, firewall adjuster, and adjustable cable.

This billet clutch quadrant replaces the factory plastic unit with an exclusive, patent-pending, double-hook design which makes it compatible with both a firewall adjuster and an adjustable cable. The quadrant is CNC-machined from billet aluminum for durability and is guaranteed against breakage--even if you have Editor Turner's shifting skills. Another nice feature of the quadrant is the placement of a groove for the cable which lessens the strain placed on the cable during shifts.

The purpose of a firewall adjuster is to make it easier to adjust where the clutch engages. In the past, the most popular area of adjustment was where the cable attached to the clutch fork at the tranny.

Nowadays, firewall adjusters such as Steeda's have made clutch adjustment much easier. This adjuster is a revised version of Steeda's original adjuster design, resulting in an adjustment range improvement of more than 50 percent. It also eliminates the bushing at the firewall and takes only one hand to adjust. The large adjustment screw makes adjustment a breeze. This adjuster works with both Fox and SN-95 Mustang clutch cables.

Last, but not least, is Steeda's adjust-able clutch cable. With this cable alone you can adjust pedal height and clutch-release point, but the adjusting must be done where the cable attaches to the transmission at the clutch fork, making it less convenient than using the billet quadrant and firewall adjuster. Even though this cable is capable of being a standalone piece, if your clutch cable needs replacing you might as well go for the gusto and get the firewall adjuster and billet quadrant at the same time.

After the installation of the Steeda components, pedal effort did increase, but it seemed to decrease after awhile. However, we're not sure if it actually did decrease or if we just got used to it. Even so, Steeda says the firewall adjuster is designed for quicker clutch reaction and more precise engagement, thanks to the elimination of the bushing at the firewall. Clutch-reaction improvement is hard to gauge, but we can back up the claims of more precise engagement. The vagueness is gone, which definitely helps, especially in racing conditions, and we can more easily tell when the clutch is engaged. At $114.95 for all three components, the ultimate in clutch adjustability is just a phone call away.
