Reason behind dual stage clutch spring?

[REDLINE]

Has Ford ever talked about the reasoning for this dual stage clutch assist spring? I believe the other trim mustangs don’t use it. I like how light it is, but as others have mentioned, I found it hard to modulate. Especially in LA bumper-to-bumper traffic.

I switched over to the steeda set and was relieved. Felt like the previous manual cars I’ve had. Anyone know why ford chose to use this set up?

My thought on it, it's a clutch protection device.

It sort of forces you to release the clutch quicker so it makes it harder to slip and generate more heat.

I agree.

Ahh. That makes sense. Deters the driver from feathering the clutch? I wonder why the eco boost and 5.0 don’t have the dual stage springs.

I’ve never driven the other trims, but it seems as though a lot of those guys switch over to the steeda as well. Is it a weight issue? I’m assuming since they just have a single stage spring, they don’t suffer from the same issues the gt350 does

There are time u need to feather the damn clutch lol. When I’m pulling up my drive way into the garage I have to feather to get lined up and past my garbage cans etc.

With the stock spring first day bringing it home I cake flying in the garage like dukes of hazard. Took it out immediately lol

It is just the opposite, the spring will slow down or delay the return of the clutch pedal coming back from fully depressed until it reaches the pivot point at about half way up. If you look at how this was designed, the spring helps push the pedal forward for the last half of travel down and helps bring it back for the last half of travel up. In fact a lot of people, including myself, have experienced the feel of the pedal wanting to stay at the floor when fully depressed and released.
I don't think it has anything to do with protecting the clutch, I think Ford's reasoning was to balance the pressure of the 2 disk setup by reducing the pressure required at the last half of travel. But that pivot point is what is hard to get accustomed to for a lot of people.
I have been running no spring for almost 3 years now and that setup has been the most comfortable for me.

100% agree. I didn't mind the stock spring too much, but it is odd. Then I installed a Steeda. Less odd, but still odd. Then I removed it and am running no spring. MUCH more natural and linear.

Oh, and the first time I shifted REALLY fast, I freaked out because my foot came off the clutch pedal upon release. Yes, my foot was traveling faster than the pedal. THAT was weird, to say the least.

I tried and could not get used to it. I just pulled the spring out and now it is perfect. Barely heavier at all and LINEAR! Much much lighter still than my Aston Martin vantage clutch.

There is a trick to lift up and out and you barely need a flathead, the details are on this forum somewhere. Absolutely do not need to bust knuckles with pliers.

First time I felt the pedal stay low I thought the master cylinder failed. Ridiculous. Ford didn't have to remove ALL the feel! Frankly it gave me a bit of a scare because it was my first full throttle on-ramp and I thought "shit I broke the car already and now I'm stuck on the highway." And for the record I have a GT not a GT350.

I like the Steeda spring personally. Flathead sounds optimistic, I used a needle nose vise grips to install. Still not bad and the pedal is still slightly firm, but MUCH more linear.

Yup, "shit I broke the car already" was that sinking feeling in my stomach that I also had. Only thing worse that that feeling, is CONFIRMING that you actually DID break the car!

I got used to it and never take it off. I took it off in my '15 GT before I traded it in to my '17 GT350. I like the lighter clutch feel and decide to not mess with it.
