Question: Is this line different than the ones that come with the ZSpeed CSC (was never answered officially it looks like) or is the ZSpeed CSC kit all I would need?

The Z1 CSC kit is all you need, comes with a SS line.

Awesome, thanks.
Got tires put on the other day and we got to talking about clutch upgrade options. Now for more things to spend my money on. :shakes head:

Hmm I've been putting this mod off for too long. Going to go with AP Racing DOT 5.1 though. Please someone feel free for a quick DIY on the install :tup:

Don't want to derail this to a fluid debate. But why does everyone recommend motul RBF600 DOT 4 over a DOT 5.1 for the clutch, when the 5.1 is better across a wider range of temps?

Believe it or not RBF600 actually has a higher boiling point both wet and dry vs AP 5.1. AP 5.1 is excellent performance for the money though, so it is a good fluid to use and a fair bit cheaper.

RBF600 Dry: 594F
RBF600 Wet: 421F

AP 5.1 Dry: 516F
AP 5.1 Wet: 369F

Note this is just the manufacturers specifications, I haven't seen any 3rd party test results to back up the individual manufacturer claims.

+1 I agree. The install is fairly simple other than sliding the retaining clip back over the new line beside the exhaust manifold outlet. There is not a lot of room there to maneouvre.

There is indeed a link in the DIY thread

It is, however, not stickied, so it may be hard to find.

DIY Stainless Steel Clutch Line

The stock line is 2-part piece of crap honestly, just get the Z1 line with some motul fluid & find a decent shop for install. It's only about an hour job, my shop charged me $89 for install & it Greatly improved the clutch feel.

Forgive the thread necro but I upgraded to the Z-Speed SS clutch hose line after nearly 300mi on the car and can already tell the different. The clutch engagement point seems to be more consistent. The dealer did it for me for free as part of the new car buy. I just supplied the line and fluid.

Old thread but worth mentioning the difference in feel after putting a SS clutch line in (only one person gave feedback saying more linear feel).

I used the Z1 clutch line and got a bottle of The recommended DOT 4 fluid, had it professionally installed (fluid flush, wrap new clutch line with new heat shielding, and install) for $100 flat.

Pressing the pedal, there's no difference. However there is a large difference in releasing the pedal. Normally you feel the engagement point as you're realeasing (non linear feel in resistance as you're going past the engagement point). Now, you actually can't really tell where the engagement point is, which is a good feeling. I'm not saying this makes the clutch feel mushy or vague. The resistance now fades gradually as the pedal is released, and if you have driven the car for a decent amount of time you already know by muscle memory for when you should start pressing the gas.

If I could go back in time, I would have this part installed again. Makes me feel better knowing that the fluids are fresh, a point of possible leak is removed (on section of line is bypassed), and pedal feels more linear and predictable. If anything there is more overall resistance in the pedal when releasing. It's a nice change and I recommend it.

Next up is adding the RJM clutch pedal assembly, and hopefully the combination of the two should dramatically decrease my chance of CSC failure.
