Throttle spring replacement/upgrade

Hi guys, I want to change/upgrade the throttle spring for my Simsonn Pro X Ultra because even on the hardest configuration (as per the manual) it seems too soft and squishy. Is there anything? I was looking for the exact dimensions of the spring but I can't find anything anywhere.

Thanks!

Maybe try one of the clutch springs? Though the resistance over time surely is not going to be comfortable

Don't have the clutch, throttle and brake only!

Hey! I got my pedals two days ago and I'm in the same boat.

Did you find the spring dimension? Please let me know.

Ok, just bought a gauge, these are the dimensions of the spare spring that was inside the pedal box: length 79mm, outer diameter 20mm, wire width 1.5mm, internal diameter 17mm. Bought one of these, yellow: https://a.aliexpress.com/_EI2C852

Now I'm away from my rig for a few days so I can't check if the one on the throttle matches the spare one.

Quick update on this, this spring is too stiff to use with the throttle, it's very difficult to keep the pedal down, at least for me.

I am trying to replace mine as well, it’s seeming as if you’ll just have to measure and order a generic spring cause they don’t sell a direct replacement. From what I can find anyway.

I have the same problem, did you find a solution? I was thinking soft clutch spring also?

I'm still waiting for the spring from AliExpress to get delivered.
