MagneRide calibration

[AMpowerJ]

So should we buy heavy track wheels for this car so we don't mess with the original engineering specs? Seems counterintuitive as it would be very easy to buy lighter wheels than what comes on this car, and it normally would provide an instant performance boost.

No. I'm looking at HRE FF15 in 19x11 @ 23 lbs each from CorteX. The suspension will adjust and regardless if it's ideal or not these wheel are approximately 10 lbs lighter per wheel than stock and that's always a good thing.

For anyone getting an R: The suspension calibrations will not work with aftermarket wheels, since there are so many possible combinations of size, weight, offset, etc. That's also why Ford Performance can't (or won't) do an aftermarket calibration to make this possible. However, this was a hot topic at a recent event, and someone suggested to the engineers there that Ford could come up with a calibration based on the GT 350 wheels, since those specs are known. If you think this is a good option, you might want to contact Ford Performance to express your opinion.

Of course they will work they just won't be optimal. Look no further than what ZL1 owners do with their cars as far as changing springs and wheels to see that changes are possible. Again they won't be optimal but the average track guy is not going to go out and crash the car or kill themselves.

That's what I thought too, but the people at Ford Performance are adamant about this, just as they are about swapping the spoilers from the R to the GT 350 or Mustang GT affecting aero. I'm inclined to believe that an R that's been "unoptimized" may become a handful in the hands of an inexperienced driver - if the original car really is tuned for ultimate performance. Plus, any built-in safety margin goes away in the hands of an inexperienced driver.

I had a long conversation with a Ford VDE about this and he basically told me the same thing. Ford employees always hold the company line. ;) The Boss owners were told similar things and it was easy to improve handling. This is clearly a different animal though. If the suspension was tuned so tight then how does it react to so many different road conditions? Think about that one.

Aero is aero. There is no pixie dust on the R wing or splitter that won't work on any other S550 Mustang. The key there is to keep the downforce balanced. Adding the R wing and splitter will have the same effect on the R or GT350. The suspension on the GT350 will be fine with more aero. The suspension is very adaptable and I won't hesitate to add more aero to my GT350 track pack. MR damping is not new or unique to the GT350.

My Boss 302 was "optimized" by Ford and I immediately bolted lightweight aluminum wheels, r-compound tires and Hawk DTC70/60 pads on it and ran 3-4 seconds faster than a stock Laguna Seca out of the box.

Even at $10k/set for the CF wheels, VERY few track guys are going to run them. You need a minimum of one extra set and realistically two sets for serious track duty. So the "real world" you'll see this coming summer is guys will be running lightweight after-market aluminum wheels on both cars at the track.

TireRack was out of our size in the RS-3 when we went to order. Our car was slower, and the tire was obliterated by the end of the race. Yeah, a couple of flat spots, but the tread was smeared across the tire. Initially we thought it might do well, as the tire felt pretty soft, and this tire was re-rated by Toyo UP to 200TW. Toyo gave some explanation about why. My guess, the "why" was because 200TW is a common thing for certain low-buck racing series, and their accountants re-rated the tire. By way of comparison, we can easily go over 20 racing hours on the Hankook RS-3, and it's faster - in our experience.

What do tires have to do with shocks? Everything.

R1R's are garbage, as you have just shown.

Adding heavier wheels to the R and lighter wheels to a track pack car will quickly equalize on track performance.

And that would be too bad, because in the hands of equal drivers the R should run away from the Track Pack car.

It's mostly the tires and light wheels.

And aero...and spring rate, and rear swaybar links, and mag progrMming, and weight savings and red badges (fastest).

Ah no! It is tires and wheels for 95 percent of the difference. While those other items will/would have an impact on some road courses no one here is good enough to tell that difference. And a true serious roader is gonna make very serious changes to even the R in terms of suspension bits depending upon the particular track they run.

Yep

I was under the impression the Track Pack and R had the same stiffer springs?
