Are you certain it's the master? slave is a more common reason for no clutch, or even a leak of some sort in the line.

Just Jap may have clutch master in stock and is open sat mornings, I'm not sure who else would have stock AND be open on the weekend. Ring first, it's a long way to go and find they don't have it. A lot of the guys are at Targa Tasmania today but I'm pretty sure the shop will be open.

In the meantime if you need to move the car you can (assuming the battery is healthy):

1. Put the car in gear, and then start it. It will move forward on the starter but should start running.

2. You can then drive in first gear with no issues. If you need to stop use the brake until the car stops and the engine stalls (then goto 1)

3. If necessary you can also change both up and down gears without the clutch.  To change up a gear drive up to medium revs, and as you take your foot off the throttle (which unloads the gearbox) pull the shifter to neutral at the same time. That's the easy bit. Then when the revs are about right for the gear you are after pull the shifter smoothly but firmly to the next gear. as a rule of thumb it will be somewhere between 2/3 and 1/2 the revs of the gear before.  

4. Changing down without the clutch is similar but maybe unnecessary to get home. Lift the throttle and shift to N at the same time, then blip the throttle. When the revs are right (higher) for the next gear down the shifter will go in.  If you get either 3 or 4 wrong you hear a horrible grinding sound but it's not as bad for the gearbox as it sounds.

Changing the master means removing 2x 12mm head bolts + the clutch line. You should use a 10mm "flare nut spanner" for the clutch line rather than a regular open end spanner because it can round it off.  There is also a pin you have to remove that holds the clutch master's rod to the pedal under the dash. Also give the clutch line a good soaking in wd40 beforehand.

      I think the pic in the first post is another car, and post 7 is OP's car with standard arms and swaybar swaybar swaybar. I can't tell what brand the silver coilovers are, and even if I could I don't know whether the spring rate is OK, if you can find a brand on the shocks and numbers on the springs that might help. Also, if you can measure the ride height from centre of your wheel to the guard that will help with advice too as handling suffers if ride height is too low

      In the first photo you posted, the colour of the control arms are the signature colour for Ikeya. Same for the swaybar, signature colour for Whiteline.  I like Hardrace, they also do hardened rubber bushes if your car is mainly a street car.  I like GKTech as well, but they use a lot of rose joints in their stuff so might not be the best choice for everyone.  The system might have been good back in its day, but it's a prehistoric system now. I suspect that most people have removed the HICAS as they want the car to do what they want to do, not what the car wants to do. From what I also understand, it isn't consistent in it's behaviour on track so it's hard to trust the car/know where its absolute limits are for track use.  Having said that, I think the HICAS eliminator kit was the first thing I installed when I bought my car. I don't personally have any experience with the HICAS system on a race track.

      Thanks for the info. Didn’t know I had aftermarket control arms already? Will talk to my garage. What brand would u recommend if I want to play around with my camber more? I would think my camber is around stock level right now or more negative now due to lowering with coilovers. I will be lower her again 1.5 cm to get some more.    also why does everyone like to remove the hicas system? Is it because most don’t work properly anymore or ppl just don’t like them. Mine is functioning as it should be right now.    thanks for the good info

      It looks like you've got Ikeya control arms and an aftermarket sway bar, maybe whiteline?  Or am I just going crazy? lol Unfortunately it won't, but what it will do is look really pretty. That's about all unfortunately.  How much neg camber do you currently have? Generally lowing the car dials in quite a bit of neg camber as it is. If you do go down this path, your best bet is get adjustable arms, toe arms (or preferably a good HICAS elimination kit) and traction rods. With all 3 being adjustable, you'll be able to dial out any bump steer that is introduced by playing with the camber settings.
