I have not installed one because I don't track the car and don't road race on the streets (retired M3 club racer). If you are not doing any of the above, don't waste your time.
Are you the same "Beefcake" that was one of the 1999 SVT Cobra purchasers that posted with all of us on Blueovalnews. com regarding the missing horsepower?
"Objectively"? Lol. We'll agree to disagree, although my opinion includes the 350R. Not talking about collector value. Talking about road racing ability.
Not nearly as fast? Curious what your 911 would do for a lap time at Willow Springs. Have not driven my 350 there, but think it would break 1:30 based upon my laps there in my BMW at 1:32.
I lived about an hour from the track in the mid-60s. My Dad drove my Mom's VW bug around the Ring with me , my Mom and sister in the car. lol. My Dad and I attended the 1,ooo kilometer race there in 1966. Fords and Ferraris.
