Sorry to be so late getting back
As Mike said,
The dish design in the pistons that I sell for the STI are engineered for the STI engine package.
The square dish pistons are engineered for a high compression 2.5L WRX headed motor package.
The round dish pistons are engeneered for a normal compression
2.4L to 2.8L WRX headed motor package.
I hope that this info helps. If not, ask away!
