So you are calling me a liar. There were many who attended the meeting with the design engineers while at Woodward Dream Cruise. He didn't have the numbers but stated downforce numbers were all but identical. I like the n/a roadster w/the skater board as well. But I wouldn't have bought a xf had I not learned of the SRT6. Just me. You will never sell me on their stick or other motor. Just no interest. Until my latest mods I was about to go back to bow ties. Love the performance of the modded srt6 motor. I would love to have the time for a v-8 conversion before I die but I think the coupe I have will be my final build w/ the ironing board. Eat your dinner on it if you think you can. It's a drying rack for shammys.
