    Clutch Helper Spring

    Folks,

    I replaced the stock clutch helper spring today with a lighter version from Steeda (for about $15). I did it in an attempt to improve the feel of the clutch and make the car smoother to drive. I'm new to Mustangs, and didn't understand the helper spring until I dug into some tech related websites. As I understand the issue, the helper spring makes the clutch pedal easier to depress and hold, but not throughout the entire pedal stroke. It begins helping at about the halfway point, making the pedal easier to hold to the floor. That's a great idea, and comes in handy in stop and go traffic. The downside (from my point of view) is that the clutch resistance isn't consistent as the pedal is released. As I release the clutch, the plates begin to 'bite' at about the halfway point, which is the same point that the helper spring stops helping, making the pedal much firmer at the same time the car is beginning to move. It's not a 'big deal', but I've stalled the car a couple times when I wasn't careful and let the clutch out just a little too far. I installed the Steeda spring because it's much lighter, and therefore doesn't 'help' nearly as much. The downside is that the pedal is stiffer when you hold it to the floor, as well as when you first start to release it, but that stiffness is now consistent through the entire stroke. It took about 10 minutes to get used to, but I personally like the new feel and am willing to trade the 'help' for a clutch that doesn't go from hard to easy, or easy to hard, as I press and release it. Also, our helper spring is different from those in the GT models. If you look on YouTube you'll see several videos about how to replace the GT model, but nothing for the Shelbys. GT's have only one spring, while Shelbys have two, along with a 'middle' spring perch. The Shelby main spring is shorter than the GT and seats against the middle perch, while a second small diameter spring seats against the lower retainer. I was able to remove and replace the two OEM springs (along with the middle retainer) with the new Steeda spring, without tools, in about 5 minutes, and most of that time was spent working my body under the dash so I could see the thing. The only 'tip' I can offer is that it's easier to do if you seat the upper spring perch first, and then compress the spring by hand until the lower retainer snaps into the bottom perch. Anyone else tried this?

    Yes, I've been using the Steeda spring since delivery. Like the more linear feel to the clutch. Tried running with any spring but had too much play at the top. Enjoy!!!

    I have been following the threads regarding removing or replacing the clutch assist spring. I have been driving a 2009 ShelbyGT500 on the track for the last 6 years. My first drive in my GT350 was a real pleasure as the clutch was so much easier than the GT500. I paid particular attention driving home this morning and found the clutch comfortable to use. Such an improvement over the GT500. What I do find that I have a problem with is heel toe as the brakes are so sensitive. First time I tried it, thought I would end up on my nose. Have some practice to do.

    Try either racing pedals or spacers to improve your heel to toe...

    Thanks Tankman, do you have any recommendations for racing pedals. My biggest problem with the heel toe was the sensitivity of the brakes. On my GT 500 (with the big brake kit and Hawk track pads), I don't have the issue. Almost seems as if the boost for the brakes is too much. I will continue to work on the problem which I have identified as ME

    Also bought and installed the Steeda spring. Directions say nothing about removing the spacer and second spring but, I did because I couldn't get all that together back in place. I think they just left out the removal of the spacer and second spring or the directions are for a GT mustang.

    The Brembos are MONSTER brakes. They haul it down like no other Mustang before. Having said that, I believe you have correctly identified the problem variable. I was also the problem but learned to adapt. If you get to GT350 track attack, the guys do a decent job re: heel and toe.

    Thanks Boss Doc, I will continue to try to improve my heel toe with the GT350. Hopefully I can improve before I go to Track Attack the first week in Oct. Next weekend I have an event at Summit Point but won't be using the GT350 but will still be in the GT 500 (I am completing my instructors course for HPDE events and don't want to be learning a new car in the middle of that process.).. I am sure I will adapt but I can't jump from one car to another--they just aren't the same

    I picked up my 2016 Tech pack yesterday. What a car! I was reading this thread re: the Steeda spring but I have no problems with the clutch. It's a lot easier to shift than my '98 GT and all of my previous Honda's.. I almost bounced my head off the steering wheel though the first time I use the brakes. They really just need to be breathed on with the big toe..
