Clutch helper spring delete

[pwp25si]

Thats for 10th gen. 11th gen service manual lists different values. 212.4mm pedal height and ~2 to ~9mm free play. there is a cutout on the carpet with metal hump underneath. I've tried playing with free play, but neutral position with no preload feels the best to me. 2mm freeplay puts too much preload on the master cylinder. Im running factory pedal stopper, and 212mm pedal height. For better pedal feel, try the damper delete.

Is this how you adjust your clutch pedal? A and B shown in step 1?

I'm really interested in removing the clutch helper spring, but I'm concerned whether doing so will accelerate long-term wear. The OP stated this mod is common among Mustang owners, so I Googled it. I discovered companies sell spring upgrades. The product description concerned me about removing the spring.

" Your clutch pedal will never fully return to stock position without any assist spring "

Our clutch master cylinders have an internal return spring that S550 Mustangs lack, hence the observations of others in this thread about the pedal returning all the way. But that's the "why" behind it.

When Ford deleted the assist spring on the GT350 (I think for the 2019-2020 cars) they added a small return spring to the pedal itself that functions only as a return spring.

If I were doing this again on a Mustang, I'd figure out the part number for the GT350 clutch pedal assembly and get one of those. But it's a non-issue for our cars.
