F1 Trigger / Stock Racer Trigger:

Change the Firing Pin Spring every 4,000-8,000 rounds.  Replace with Wolff 4 lb Firing Pin Spring.   My personal rule of thumb is to replace the spring before any major match.
Clean and regrease connector-trigerbar interface every 1,000-5,000 rounds.

Street Racer Trigger / Stock Racer GSSF Trigger:

Change the Firing Pin Spring every 10,000-15,000 rounds as a preventitive measure.

All Triggers:

I reccomend replacing the coiled trigger spring every 1-2 years or every 20,000-30,000 rounds as a preventitive measure.

Heinie Sights and CGR Race Cut Heinies:

Wipe off the rear sight and apply a light coat of oil, make sure to rub it in so it penetrates.  I prefer WD40, it penetrates well and provides excellent corrosion protection.  Make sure to wipe off excess oil.
Your climate and mode of carry will make a big difference on how often you should do this.

Recoil Springs:

This will depends on the load you shoot and the type of springs you are using.

Stock Springs:  Change every 15,000-25,000 rounds as a preventitive measure.
ISMI Springs:  Change every 5,000-10,000 as a preventitive measure.
 

Mag Springs:

Factory Length mags:  Replace the spring every 2 years or every 25,000-50,000 rounds.
Mags with 140mm Basepads:  Replace the spring every year or 10,000-20,000 rounds.
Mags with 170mm Basepads:  Replace the spring every 10,000-20,000 rounds.
