I've heard a LOT about how important an upgraded brake pedal is; but not much about the loud & smoke pedals. So, thoughts?

There's something about the cohesiveness of installing a full set of matching components. Okay, I'll just say it, some of it is just the feeling of a complete "job done"! I've done it a lot on actual cars when say a new pressure plate would suffice in a clutch repair, I sometimes replaced the throwout bearing, clutch fork, etc.

So, to some it sounds pretty dumb I suppose. But I simply don't know enough about sim components. Full sets of higher-end pedals are pricey, I realize that. Is that the reason so many only upgrade the brake or is there no reason at all to include throttle and clutch pedals?
