    The hydraulic system?
    Or picking up the tab?

    Yeah I’ve been reading and think I’ll play it safe and install the steeda spring and perch. Not worth taking a chance.

    You think that is bad advice because...? I'm going to guess because of that vendor that sells replacement springs.

    So I am going to go crazy here, I am going to say the emperor is not wearing clothes.

    1 .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
    My personal experience was that with the spring removed on the OE setup (PP, Clutch and Flywheel) it felt in the range of every other OE clutch I have driven. Hmm.. that doesn't mean much so let me list all the OE clutches I have driven in no particular order:
    87 Toyota MR2
    92 Toyota MR2
    88 Honda Prelude
    00 Mazda Miata
    89 BMW 318is
    94 Audi S4
    93 Mazda RX-7
    94 Mazda RX-7
    95 Nissan 240SX
    95 BMW M3
    93 BMW 325is
    05 Subaru Legacy 2.5GT
    92 Subaru Legacy Turbo
    02 Subaru WRX

    I currently have an ACT HD Twin Disk in my 2015 GT and there are cars in that list with heavier OE clutches. I daily drive my car in city traffic. Unless you are exceptionally feeble, removing the OE spring will not change the clutch pedal weight to the point the car is uncomfortable to drive.

    2. By negating your factory clutch assist spring you will notice chatter/NVH from your clutch pedal.
    I have none. Based on my personal experience there was no change in NVH, there is no chatter. Being fairly mechanically inclined I can't even fathom how removing an assist spring would cause this.

    3. Your clutch pedal will never fully return to stock position without any assist spring
    Completely true, my pedal is about 1/4" lower than it was at the stock position. They didn't quantify it, I did though. There are zero drivability effects, and really this is not significant.

    4. 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.
    On second read I realized a lawyer must have written this statement. Everybody reads this and thinks leaking=permanent damage=slave cylinder replacement. But that isn't what is said at all. For starters, how is the .01psi of line pressure (this is hyperbole, I have not quantified the line pressure) the clutch pedal will develop resting against the master going to damage seals? Is it going to push them gradually out of place? is it going to deform them? Obviously not, it doesn't have enough energy to harm them or displace them, how do I know this? Because the working pressure is orders of magnitude beyond this static line pressure, there is no way the seals could withstand that through thousands of cycles yet be so fragile as to be displaced or damaged by a clutch pedal assembly resting against the master. Again, I opened my clutch hydraulic system two months ago, fluid didn't spurt out like a punctured artery when I opened it, barely anything came out. The absolutely worst a tiny amount of static line pressure can do is barely pressurize the hydraulic fluid so that the seals could weep slightly. But even that is a stretch and it is disclaimed with the word may.

    So please tell me how removing the clutch assist spring is going to harm anything. Somebody, anybody, can you provide evidence or an original thought?

    Good post man. I agree with everything you said. I also agree with one very key point you didn't touch on in this post but in an earlier post.

    " 4. People have been running with out a spring since 2015 and there hasn't been a rash of issues. In my opinion it is a safe assumption that If running with out a spring caused problems it would be forum wisdom by now."
    - I think that statement is key brother and your absolutely right. -

    Steeda is a great company but like any other company there going to have selling antics and gimmicks to sell there product. Writing things like running no spring may damage your slave cylinder will only amplify in selling there product. I love the fact they use the word may and do not support it with any factual proof.

    At first I liked the steeda, convincing myself like many others that it is such an upgrade over the stock spring. Fast forward now a thousand or so miles later and I put the stock spring back in. I find the steeda spring not to have a more linear feel. To me it basically has the same bite of engagement and feel as the stock one only in a non dual spring way. What I come to not like about the steeda is half way through the release I feel that it ejects your foot off the clutch making some shifts not so smooth.
    I personally like no spring the best and it is thee most linear. It is also the most like other previous older gen mustangs that I have owed (total of 10 now) and driven. The only reason I rock the stock is that I find it incredibly light and just excellent for daily driving. That and you really do get use to it if you just give it a chance and put some miles on it. I can assure you I didn't put the stock back in because I'm afraid of some catastrophic blow out or failure, lol lol. ....

    With all that said I really I'm liking the stock again but if I feel like a change again, It will definitely be with no spring. As for the steeda, it sits in the bottom of one of my tool boxes for now but in time I'm sure it will make it's way to the trash.
    However like steeda says its only 20 bucks to try it. There absolutely right, twenty bucks is my big blind every orbit when I play poker on tuesday's. :)

    Don’t go crazy ...not worth it.
    Can you think of any other systems on the car that are influenced by clutch pedal position?

    Not sure if it's an '18 thing or a GT350 thing, but the stock springs aren't all dual coils.

    Had this perch/spring for about 3.5k miles and have had a bad squeak/noise a few hundred post install to the point where the pedal was getting harder to depress recently on starts.

    Took a look today and the perch shaft is digging into itself and marred. Way beyond needing grease. Maybe just bad luck but end of the day wasnt worth it. Maybe if the quality had been better.
