Old response. I have a 2019 (or 2020, I don't remember, doesn't matter) Fox Factory Grip2 160mm. I'll be installing a DSD Runt (basically the same as IRT) and I have read great things about those Grip2 owners that have made the installation. Might be worth a shot at $200 before changing out your fork.
