370Z Clutch Line Upgrade - Experiences?
 

For a daily driver and eventually upgrading the clutch to handle more power, what do you guys think about clutch line upgrades?

It may be overkill for daily driving, but I don't mind if it improves clutch pedal feel and longevity as well.

for it def made the clutch line feel smoother and more linear and more consistant. before while driving it would sometimes feel soft, sometimes harder. SOmetimes it felt like it would immediately grab and sometimes had to let it out all the way before it grabbed.

So definitely worth it for the small cost.

Also theres Viera, who's clutch would get stuck to the floor on normal driving a few times. He upgraded his clutch line and it hasnt happened since. While it may not have fixed the root cause it surely did seem to help.

How much does installation for this cost?

shouldnt cost much just gotta install and bleed the line.

but while your at it you should upgrade to a better clutch fluid. I went MOTUL in mine.

still should be maybe an hour?

I have no technical car skills what so ever other than maybe change tires and oil change.. The dealer quoted me $400... I dont know how much to pay and dont want to get ripped off..

nah eff the dealer. find a shop to do it. not sure where you rlocation really is but ask around in that regional forum area for a reputable shop.

It's a great improvement to install a stainless steel clutch line and higher rated brake fluid. Use a Dot 4 minimum and better quality like Motul or ATE is preferred.

Don't forget to insulate the line well to prevent heat soak from the exhaust. It doesn't hurt to add more insulation for extra protection.

$400! That's insane. I personally never felt much of a difference when changing out the line. Little bit firmer but hard to tell.But it helps for the more spirted days. Sure you heard of the issues of people clutches sticking to the floor. This has happen to me. It's pretty wild. All this went away with the upgrade line along with high temp fluid change. Reduces or eliminates the line from expanding or flexing that comes with rubber lines.

Sweet... if you guys have recommended brands and part numbers from experience, please share. I'll probably try to get this done when the clutch and flywheel gets changed this summer.

thats the one myself and alot of others have.

As for the fluid, was MOTUL, but i forget the number : /

That's it!? Wow, that's cheaper than the SS brake line kit. I'll definitely get some of this and the MOTUL fluid and get it all done this summer. :tup:

thas what i beentelling people. for 29 bucks.. comeon. we spend that amount on emblems and stuff!

+1 on the Motul

Haha yup... imagine getting the turbo kit installed, getting the brake upgrades (pads, rotors, lines, and fluid), clutch upgrade (clutch, flywheel, line, and fluid), and then the 10 hr. drive home from Houston to Kansas. I'm hoping for a good driving experience.

is there a DIY for the SS clutch line? searched but cant find one.

Works like a dream, and I feel like its a new car! No regrets....lol def. get it done!

After reading the reviews I ordered it yesterday with 2 bottles of motul fluid, looking forward to seeing the difference

Are you planning on installing yourself ? If so please do a DIY as I'm interested in doing it also..

I have a shop that does all my work for me, it should be a pretty straight foward install tho

The installllls really easy. Its bleeding / replacing the fluid that takes time

I have 2 1/2 bottles of that motul fluid, that should be enough right?

uh yeah.... plenty

I ordered the Z1 lines, and then sold it because the ZSpeed HD CSC comes with the new lines pre-installed. I'll let you guys know in July once all the work on my car is done.

new lines pre isntalled?

this clutch line is outside the tranny?

I think your thinking something else...

Nope, it replaces the hard lines as well.

It's a good thing it's only $29, lol

What would one use to insulate the clutch line from over heating?? Besides adding different fluid i mean.

It already has some wrap on it stock. Just take off the stock stuff and re-wrap it around the new stainless line. You don't have to go overkill on it.

The Motul is RBF600.

I had a spongy clutch pedal and the Z1 stainless steel line along with the higher temp DOT4 fluid fixed it. I can't recommend it enough.

Personally, I installed the line while I had my cats off. I couldn't imagine trying to get in there to unclamp and unscrew the stock hose with those things in the way. Pain in the ***.

yup, i tell everyone i know, for how cheap this mod is, its reallly reallly realllllly nice and worth it.

The #1 thing is swapping out the fluid, it doesn't hurt to do the line but high temp fluid plus a little bit of insulation will make 99% of the difference. Put some MOTUL RBF600 in there and bleed it nice (which can be a bit tricky) and it is a huge improvement as things heat up.

The clutch line runs at a much lower fluid pressure compared to the braking system so the SS can be considered a bit overkill. It's cheap enough though, so if it makes you happy go ahead and do it at the same time.

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.
