Until any of this gets into smoke testing in a wind tunnel it's an exorbitant amount of speculation as to which cooler guard, combination of OEM aero part(s) etc effectively create more CFM through the heat exchanger aka oil cooler. I view multiple posts on this issue all over this site.
Turner Motorsports runs M4 GT3's. I bought it. No temp increase(s) or other issue at this time. The EU lower spoiler is also available and again w/o wind tunnel eval who the hell knows?
Turbulence, 2 near 90 degree dams w/the EURO part. The front dam and the oil cooler dam/sweep. Resulting CFM airflow increased through the oil cooler.....with one or the other or both?
