The GT350R does have significantly more HP. My assumption is that it's also lighter than the Mach 1. I would be very surprised if the GT350R brakes aren't better than those on the Mach for holding up after several fast laps.
Very nice! Good to know Herod can do it. I am in the process of adding the Handling package and saving the suspension/springs for last. A friend at a Ford dealership says he can tune it to a HP but it’s complicated and we gotta wait a few months.
Do you have a source for that or a part number this is very interesting and I didn't seen this mentioned in any of the articles about differences between PP1 GT and Mach 1.

In export markets (like Australia) we don't get the option to buy the HP car, or GT350, GT350R or GT500. I would have ordered HP car direct if it was possible. Since the Gt500 is unavailable I used the Mach 1 as the base for a car with similar performance with the transmission I wanted (Tremec).
But you can buy an Non-HP car and convert it to HP car sure it will take some time but HP cars are not magic they are more aero, camber plates, springs and wheels+tires. For the wheels and tires you have better options with Apex (lighter) for springs you have tons of options for camber plates as well and even for aero there are better options but it's easy to source from Ford Performance anyway.
Yes all true, I was originally refering to the lack of a factory option in export markets and the US HP model at an increased price that is well below the cost of the additional parts is a primary issue.
I would expect that the most significant change to the car performance (considering the exported configuration) would be replacing the 3.55 limited slip diff with 3.73 Torsen. The handling package is good for the track and looks, but for a daily drive does not contribute as much as the diff.
How does the diff contribute to the daily drive ? (Assume you're talking about actual differential, not ring gear).
I kind of agree with that though I'm kind of happy with the 3.55 sure need to upgrade to 3.73 Torsen eventually but this could wait for sure. Regarding the other options I try to get my 2017 close to M1 HP spec and there is one big difference that is the TR-3160 which for me is a better trans for track. Regarding M1 non-hp vs HP I think considering they are the same minus the wheels and tires I think wheels and tires are the biggest difference and if you need wheels better buy something lighter as the HP wheels are still solid 31-32 lbs of a wheel. So there is performance to be gained with after market there even on HP car. Steeda btw had a lovely clip on improving the Mach 1 with aftermarket and the difference in times was insane.
Yeah -ring gear teeth count obviously makes difference - diff itself - not really (in street driving).
