I'm looking up Ring end gap on Alldata and its giving me these values.
My current measurements on 1st ring are .406mm (.016in)
2nd ring is coming in at .559 (.022in)
Is that too much on the tight side?
Plans for the car are to stay on factory T25.
I'm using factory replacement pistons.

You are actually on loose side if comparing with the OEM spec but it would probably be fine, better than too tight.

Those are fine for a low boost low cylinder pressure spec. Don't be worried about them. I opened up the factory gaps on a semi-stock build and feel great about it.
Your good! :thumb:
