What did you do to your S550 Mustang today?!

[The Demon]

not at Matt's Emporium of Speed, that's for sure. I've got 60qts of full-synth oil on the shelf, but nooooooooooo.

I can be there in three days. Save me a spot.

well, you're supposed to replace the spring with a lightweight one. Otherwise yes you get floppy-pedal but really it doesn't matter since the floppy bits isn't applying hydraulic pressure to anything anyway. The moment you push on the pedal though you're actually moving liquid.

I found the Ford spring to be entirely disgusting since it completely erased the 'detent' you feel when you transition from just compressing the spring to actually moving the piston+fluid.

This - what spring did you use? I felt instant improvement and more linear feel. Even without a spring, it was an improvement.

Where is that being done?

I did, it was a 30 or 35lbs spring as opposed to the 80lbs (I believe it is) stock one.

It created a small amount of slop/play at the top and there was no feel at all. Had no clue when the clutch was actually starting to bite. Reminded me of smaller cars (civic, focus, etc.) that have super soft/light clutch pedals with no feel. Felt very disconnected.

It's supposed to have the opposite effect. Stock is too soft and leaves the engagement point hard to feel. Taking the spring out makes the peddle stiffer and more communicative.

Well we may have a car washing going at Matt's Emporium of Speed this weekend. Perfect timing!

Which spring did you install? My Steeda spring was an improvement over stock.

Hmmm, maybe I'll just remove the perch and see how that feels.

Pretty much everyone else has the opposite experience you had with the softer spring. The softer spring helps get a better feel for when the clutch bites is what most say, and that was my experience too.

Installed a clutch spring. Drove maybe 2 miles, promptly went back home and put the stock spring back on.

Yes, it is strongly advised against not replacing the spring with another one, i.e. don't leave it "spring-less."

I see he didn't get the Steeda, which is supposedly great. I wouldn't leave it without a spring tho.

The original one in the S550 is a 185lbs/in, not 80. At least per Steeda.

Per their website it's 185lb/in by design and Steeda's is 35lb/in.
I've read really good things about the Steeda one on here and on the site itself, so I think I'll give it a shot.
Worst-case scenario, if it doesn't work well at all, I'm out $30, which ain't that bad of a gamble to see if it'll improve shifting.

I think you meant the stock is too stiff, not soft? I think the original, per Steeda, is 185lb/in (which is a stiff spring) and the one you can get from Steeda is 35lb/in, which would suggest lot softer and easier to feel the grab point.
Unless I'm real dumb and am not getting this right.

Softer spring gives a harder (and more consistent) pedal, the pedal gets harder again with no spring




My thoughts on it :

Impressions ... ? Well, bear in in mind I’ve drove manual for 27 years and didn’t really have a problem with the original setup, but the spring was cheap and I already had it in the spares box so I had little to lose. Normal driving it only makes a little difference on initial setting off, it kind of feels like the pedal is a little harder, BUT only through a bit of it’s travel (about a third of the way through its travel as you release the clutch). It does kind of feel a bit more ‘linear’.

So after driving it around the estate so I had plenty stop start driving, I could take it or leave it - no real benefit (for me). However, I reverse up my drive through a gate on a bit of an incline at a speed where I’m right on the biting point of the clutch - in that scenario there was a marked improvement in feel / control. On those grounds alone I would recommend it (for me), especially considering the nominal outlay

Out of curiosity, why the need for some type of assist spring other than making the clutch peddle artificially lighter? Many cars from the 80s-90s had hydraulic clutches w/o assist springs.

"Installed" these. They don't quite match the grabber blue stitching but I still like the way they look

Also spent half the night trying to figure out which spoiler I want. Narrowed it down to these 3, with preference of the first 2.
