I want to put some ctr piston into my bone stock jdm gsr. I searched and found nothing on it. I was wondering if it will be safe to put ctr piston into my jdm gsr engine? will it have any issues? how reliable is it?

Thanks guys

 

ITR pistons would be a better choice for a daily driver, even PR3 would be good.
