Just removed springs and installed AKG clutch bushings. Removal of spring definitely improved 1st to 2nd gear change. It's more smooth. SKG bushings also reduced a lot of lateral movement, but installation was super AIPA as it was nearly impossible to reach bolts, nuts, and clips for removal with tools and hands. Someone in this thread recommended installing SKG bushings but one thing you have to know ahead of time is that end clip that's holding the clutch pedal wouldn't go back in unless bushings were grinded. I had to grind about 0.4mm (total 0.8mm) on both sides of bushings in order for the end clip to slide in to lock. Eventhough this job took me a few hours, I'm happy with spring removal and bushing replacement.
