It would kill some of the strength of the magnet. By weakening the magnet, you should get more top end and less torque. The amount of the effect would depend on how hot the oven was and how long you let it bake. I wouldn't recommend it unless you are really good at motor tuning and knew exactly what you were doing.

I was hoping thats not what you meant but knew it probably was lol.
Its an old trick but easy to detect in tech.

You can drop a rotor's strength pretty easily if you do it right.
Theres no putting it back though if you dont pay attention to the timer.
And it tightens up your gearing window in my opinion.

I'm having a hard time visualizing this, You really mean something like a 60ish spur and 50ish pinion?

No. Literally - 55 spur - 55 pinion or higher.. As long as whatever differential or spool outfitted on the car can accommodate it, some competitors outfit the smallest spur they can find, and correspondingly largest pinion.
Depending on the track and other conditions - some would even run higher than 1:1.

DIdn't realize that the GT12USA Spec was only allowed to be run on black carpet.
or that all black carpet is exactly the same.

If someone needs to or wants to run a diff ... what's your problem with it? This class is suppose to be great for beginners. Jebuz.

I do when using rubber tire. It works awesome.
However, in this forum, since the topic is centric to foam tires, I run a spool in that case.
