I did a very quick google search which didn't throw up much, but I'm also lazy.

Not big money in the grand scheme of things.

Edit: They've just cancelled the order as they do not ship to the UK. Time for more google - guessing these will work: https://uk.rs-online.com/web/p/shaft-collars/1746790 or https://uk.rs-online.com/web/p/shaft-collars/1746789

I’m a UK expat living in the states. If you like you can send them to me and I’ll ship ‘em to you. I send stuff to my folks back home all the time.

Thanks, appreciate the offer.

I've managed to order the following, albeit on back order as they're due in May which is ahead of my GT4 delivery (plus free shipping and cheaper):

I have a Fabspeed Valvetronic installed, does anyone know if a shaft-collar setup would work? Or would I have to go the grub-screw route?

You might be confusing two modifications.

I will vouch for McMaster-Carr quality, as we order just about everything we can from them for our workplace. They arrive fast and are of great quality.

The fabspeed valvetronic uses the factory PSE operation. It's droney and muted up until about 4k, then the valves open up. I just plugged the vacuum hoses like others suggested and it works great.

Installed the collars last night. What a great idea this was by whomever came up with it. I eyeballed the distance from the valve for the install at around 2cm.

Makes a great difference! I didn’t mind the sound before but the sudden increase in tone at 4K rpm was just weird. It now sounds consistent all the way through the revs which is lovely.

One minor thing I noticed with my collars during the install (McMaster) is that if I push the valves closed with my hand the collar slightly touches/scrapes past one of the nuts attached to the valve. It doesn’t make an audible noise from within the cabin and it still works fine but wondering if anyone noticed the same.

Thanks for the Shout Out!

Regarding the slight scrap of the collar against the Actuator Stud, Which Part Number did you order??? Seems like you ordered the 20mm OD versus the 16mm OD Collars....?

Try rotating the collar slightly, as their outer diameter is not totally round. You may be able to get a little more clearance and eliminate the scraping.
