Hey guys, im not too sure what to expect with my car anymore. I have a 2012 sti with a little over 13k miles. Never beat on the car, but drove it aggressively at points, before bringing the car into the dealer i was running COBB stage 2, and a tbe. I have a cracked 4th ringland and subaru is giving me a "good-will" one time repair. Not a new short block, just a repair. I was thinking about replacing the current pistons with forged ones since they already have the motor broken down, and will void the warranty on the pistons after this repair anyway. Does anyone have any suggestions one whether i should replace the pistons with forged ones or just leave the oem spec ones on there?
