Put this on my FL5 as I plan to track it. First time out it worked fine, but I did get a CEL (ECU detects the thermostat opening sooner than normal, so since water temps don't reach a target value before it opens, a code is thrown), which others had warned about. Talked to my tuner and he was able to take care of that so I don't get a CEL from it anymore. Combined this thermostat with a PWR racing radiator and the Acuity reverse flow hoses, and I've had no overheating issues at the track.
Recently ran my 1st autocross with this bar in place, and noticed the car handled much better than it had last season. Was wondering what the difference was, and then realized "oh yeah, I've got this bar" as well as some camber adjustment ball joints. A bit more negative camber combined with this bar has really transformed the handling of the car.
Very quick install. I have a DC Sport strut bar that was kind of in the way, but it didn't cause any issues mounting the catch can.
