Hi there, my suggestion if considering upgrading all pedal springs is to use the original brake spring left over from the brake mod, move it to the clutch pedal, and if you wish to upgrade your gas pedal to a firmer feel use the original clutch spring.
- GTEYE Spring to Brake Pedal
- Original Brake Spring to Clutch Pedal
- Original Clutch Spring to Gas Pedal
Although personally, I prefer the original gas pedal spring for throttle.
The original brake spring is perfect for the clutch.
In my opinion it would be unrealistic to install a "progressive" spring to the clutch pedal as most real-life clutch actions are not progressive, but rather "digressive" which is not achievable with a coil spring alone.
Brake pedals are generally progressive, the other two are normally linear, then it just comes down to preference on the stiffness.
