No, from the other side of Arnage. Mulsanne is to the East of Arnage, and I am suggesting the west. The ring road that passes in front of the circuit either goes east to J23 of the A28, but if you take the A11 west you pick up the other end of the same road, this time west of Arnage. Coming in that way you'll avoid the big delays that occur race week, you come off the ring road well short of the circuit and drop down to Spay and then Arnage. Look the route up on Google Earth or even, if you have one and they still exist, a map. Much easier to visualise. In my book it'll be a lot less hassle than coming via Auchan (the worst idea that in my opinion) and we all know that coming off at 23 of the A28, especially the Friday or Saturday, takes several hours to get to the circuit. Last year during the Classic it took me over an hour to get home at 11am, all 7 miles of it, on the Saturday morning before racing had started, but those going to the circuit from the A28 were littered along the verge, overheated.
