Feels like it's a box out affair now.

Nearly feels like the throw out bearing has been installed backwards (hence the noise you've mentioned). A single disc clutch should not make any rattling noises at all.

Could be onto something there

Thank you for all the help guys, since I backed the pedal stopper off a bit and made sure there was a bit of free play at the top and it's driving a lot smoother and gears are selecting without hassle. It must have been more adjustment needed like a few suggested. After the clutch has bedded in a bit I'll check it again. 

I sent the videos with the sound to ACS and they said this:

"What you are experiencing is harmonic noise and nothing to do with the bearing. The Australian engineers have said it sounds like gear noise/gearshift rattle
This can happen  on some vehicles and depends on the condition of everything else. There may  be some worn  bushes in the linkage which could be cured by replacing them or some gear rattle which may be 'dampened' with some tougher gearbox oil.

well, massive thumbs up to ACS for taking the time and getting the right people to look/listen to it. Goes to show local support is worth it's weight when you have an issue.

Yes mate I'm happy with their response to my queries, it's difficult to diagnose obviously without seeing the car in person. They allowed me to get in contact to pass onto engineers.

It made sense to me afterwards to take the clutch pedal pin out, let it take the pressure off the rod which moved out slightly, and adjust from there, with a bit of play in the pedal before engagement. 

Obviously I'm going to go normally until everything is bedded in, I treat all my cars with respect anyway. 

Cheers lads, this forum is a good community, hardly anyone replies in the UK forums like they used to do. 

It's much appreciated

Everyone too busy going to get pissed at the pubs and hitting music festivals.

My Aussie mates living there doing just that lol.

Yeah lol probably. 

Can I just ask if anyone knows obviously. 

With the adjustment on the pedal rod maxxed out, will it cause any problems with anything? (picture on page 1)

I made sure the pedal had a bit of play before it moved the rod also. 

I suppose I could go back a bit and see if the gears still change smoothly, 

What do you reckon?

    • Sorry no - The sandtrap adventure ended the day, happened at the end of the last session. At that time I wasn't hearing any weird noises nor were the brakes shuddering anymore. It was only when watching the videos that I remembered I had these sounds early on!
    • Did the noise appear after your sand trap adventure? Could be something got dislodged and is playing rub rub. Even a rock wedged somewhere.
    • Is there a shroud around the tailshaft spline into the back of the box? They can rub and make a horrible noise if they are not on straight/damaged. The heat might have caused it to grow too much in one direction and rub.
    • Strangely I noticed it either disappear later in the day, or not be present. I definitely noticed when I was crawling around that open wheel thingy entering the pits (that part was audible in car). Driving home and commuting around town for example, I didn't hear it. It's plausible that it was a brake disc or something still slightly in contact. The brakes absolutely felt BAD for the first couple of sessions, huge amounts of shudder and grinding as they got up to temp - And then I actually just forgot about it as the day went on/didn't notice it. The videos were from the morning when this was more present than the afternoon/drive home when it wasn't. I've asked around and got a variety of responses including handbrake shoe contacting hub, CV joints, CB tailshaft bearing as above, and clutch input bearing. I didn't test if it disappeared when clutch was in. I haven't noticed it in any of the other videos nor did I notice it when driving to that extent. More or less hoping the microphone at the rear license plate giving some kind of clue of 'something' but it looks like "spin stuff and see if you can notice it" is the way forward here. I could be smart and use the gopro mic and re-mount it to that location to see if the sound is still present at low speed actually. Sounds like a decent test whenver I have the CBF'ness to drive the car again. Given it's almost 40C for the day of the track day and the next 3 days after, the CBF is high. All I've done since getting home is unpack the car, remove the remnants of the lip and undertray and left it there. I was surprised how well the PMU Club Racers actually worked. The brake performance on the track was absolutely fantastic, best I've ever personally used, no fade whatsoever and the bitiness was almost too good, I was scrubbing more speed off than I needed to, but I also ended up infield when I started trying to scrape off ... less speed.... so...
