What did you do to your S550 Mustang today?!

[GT Pony]

You ARE correct that the spring doesn't change what 5mm of piston movement does to the other end of the hydraulic circuit and to the clutch plate slippage. Nobody claimed anything of the sort and only you keep harping on it.

The spring doesn't change anything mechanically or hydraulically between the pedal motion and the clutch plate motion. It's only changing the feel between your foot and the clutch pedal. If the pedal is pushed X distance, the hydraulic cylinder moves Y distance and produces Z hydraulic pressure, and the clutch plate moves XYZ distance ... regardless of what spring is installed, or if there is no spring at all. Nothing changes except the FEEL and the ability to better modulate the clutch motion and the initial bite and lock-up with your foot.

The *position* of the pedal vis-a-vis the floor is ABSOLUTELY different between Steeda/No spring vs Ford spring and where the relative knee angle is at BITE and RELEASE point.

Now it sounds like you're back to claiming it changes the relationship between how the pedal moves and how the clutch operates - as in X distance of pedal movement changes the Y distance the clutch plate moves - it really doesn't. You think it does, because the required foot pressure and modulation ability feels different. But nothing is actually changing between the mechanical motion of the pedal through the hydraulics to make the clutch operate.

The 'spring' also changes the perceived force needed to control the movement of the hydraulic piston at the various positions within said activation range. THAT is what we're talking about.

Yes, and that's what I've said all along. It changes the feel/perception and control/modulation ability with the foot on the pedal. Anything beyond the pedal has not changed mechanically or hydraulically. It's the same exact motions and same exact hydraulic pressure involved.

Anyway, you can believe what you want, but the fact is the spring only changes the foot feel/pressure required, and the modulation sensitivity of your foot on the pedal throughout the pedal stroke ... not any of the mechanical or hydraulic functionality. Thread OT discussion over with me - rant over.

This is what Steeda's site cites for that product:
"Many new Mustang owners have found that taking out the stock OE spring will give you somewhat similar results, but realistically the clutch becomes far too heavy especially if your Mustang is daily driven. Most owners fail to realize the prolonged effects of simply taking out your factory OE spring and not replacing it with another spring. By negating your factory clutch assist spring you will notice chatter/NVH from your clutch pedal. Your clutch pedal will never fully return to stock position without any assist spring, and over time your slave cylinder may begin leaking due to constant pressure on its seals from the clutch pedal not returning to the stock position."

That sounds like they're saying the cylinder and parts are not made to withstand lack of the spring. Maybe cars are build with less margin for error, I don't know.
What they're saying makes sense though - if the pedal never returns, it's like you're always feathering your clutch for a long time or resting your foot on the clutch while driving, each of which is a known "no-no."



That's pretty sweet, especially when my experience should be similar as we both have a Bullitt (although I think that doesn't matter).
Did you just put in the spring, were you able to reused to clips that hold it on?

My mechanic installed the spring. Out with the old, in with the new. 2 minutes all done.

I understand that some people have health issues but yes, if you are mobile and have some dexterity (and own some mini vice grips), it’s a very quick change

What's this thing you call winter ?

Yeah I'd be careful with that kind of talk after the Jan-Feb 2021 winter Texas had....

Right, am aware of this, looks super simple on the video. I just need to take an hour to sit down and do it and swap my cabin air filter too... 18 months and 27k miles on the factory one may be too long.

New hood vents.

After it's bath. And in case anyone is wondering, you can def see these well from the cockpit

New hood vents.

Sometimes I regret picking Velocity Blue over this color. Beautiful car.

Not bad. My fav hood vents are Roush RS3 vents but apparently Roush will not sell them to general public.

I was skeptical, but that green is just dark enough, and if cared for properly it has this wet look to it.

CJ Pony will.

Had the Ford Performance half shafts installed and used my new SVE drag wheels with the ET Street R tires for the first time.

Wallet in right rear pocket? Avoiding that will net a thank you from your back.

Got my alignment taken care of after BMR minimum drop spring install. No issues getting it into spec with BMR camber bolts
