Given IAS is standard in my 2020 M850i coupe it just came along for the ride in the purchase. For daily driving it is a godsend to reduce the turning radius, e.g., U-turns, tight cornering in the Starbucks drive through, etc. Normally I drive in Sport Individual with the steering, transmission and engine set to Sport along with the chassis (aka suspension) set to Comfort) and have had zero issues with IAS from a predictably standpoint when corning at speeds up to 85 MPH.
That said when truly pushing it I'm in either Sport or Sport Plus and I've done 95 to 105 MPH on winding mountain roads with the curves flagged at 65 MPH with the M850i performing flawlessly. Obviously there is no way to compare what the driving experience in the M850i would be without IAS but at this point I'm 100% happy with it.
