G27/G29 brake spring strength

[Sfrost]

Just want to find out the spring strength/ technical specifications of the logitech pedals standard brake spring so I can order one of similar resistance to replace the T3PA's accelerator spring. In addition if anyone knows the spring strength of the GTEYE brake mod for the logitech pedals that would be greatly appreciated as well so I can replace the brake spring on the T3PAs as well.

Thanks in advance guys

Found the info I needed on the GTEYE website where they have a handy graph showing how the force changes with compression.
