There is actually a very minor side effect if you take out the clutch helper spring.

Removing the spring can cause cruise control to not set your cruise speed properly. You'll still be able to turn on the CC, but may not be able set the speed.

Reason for this is because removing the spring causes the clutch pedal to loosely fall few mm. (Note: Pressing the clutch even just few mm while on CC disengages the cruise, just like applying brake).

That being said, that very little drop on your clutch pedal will fool the cruise control, making it seem like the clutch is applied. (To put it in another way, it's like trying to set your cruise control speed while applying the brake, it's not gonna turn on)

It may not happen to you. But I had that happen few times. My cc works for the most part. If it doesn't, I just tap up the clutch pedal using my foot and then set it.

It's really no big deal at all. But don't be so alarmed if your CC doesn't work without the spring.
