Default Timing Belt Replacement Check List, am I missing anything?

Hey guys,
I just bought a 2011 WRX Hatback with 154k miles. I have been trying to reach out to get the service history but no luck.. So seeing as the timing belt may be WELL overdue I decided to go and do this while im installing some other mods.

Can anyone let me know if i'm missing anything or if theres something I should add while im getting it done anyways I would really appreciate it.

Heres the list:
-GDT Cylinder 4 cooling mod
-IAG Air Oil Separator install

-Gates Timing Belt kit with Water Pump
-Gates super strong alternator and powersteering belt
-OEM Thermostat w/ Gasket
-Valve cover gaskets replaced
-Cam Seal x2?

I have read other posts where people have recommended replacing the Crank Seal, I just had my rear main seal replaced when I did the clutch job 1k miles ago, Is this the same seal?

Thanks to all

If the cam/crank seals aren't leaking, there's no reason to change them. Does that kit come with new idler pulleys?

I probably wouldn't have gone with the racing Gates Timing Belt just the regular one. I would recommend an OEM water pump also.

Just did mine last month. No issues so far.

Yup, skip the racing timing belt. And make sure you get the Japanese kit not the Chinese kit. And so much yes to OE water pump, although I wouldn't balk too much at a japanese manufactured one.

I've seen more cheap aftermarket water pumps fail at 30-40k miles than OE water pumps failing at 200k.

Don't see an A/C belt in the list. Is it in the Gates kit? If not replace it unless you are doing without A/C.

Any experience with Aisin water pumps?

When I did my timing belt I used all oem. I spent around $700 in parts. The aftermaket parts are made in China. I read online post about the water pumps failing prematurely. Remember you get what you pay for, you dont want any of these parts failing.
