AIMGAIN has a full kit and also a spoiler.
LEXON has a front lip.
AIT/SETUNED has universal CF sideskirts and CF rear canards that fit on the ISC.
ISCJONNY has exclusive ISC CF front lip.
There ARE parts for the ISC out there.. but it is very limited and not the easiest to get at the moment. Almost all parts are based out of Japan or Asia and requires 4-6 week wait times and expensive shipping to receive.
