Interesting question.
The Fray guys run a stock chassis with a mere 14-Ohm armature. But they know how to get the best performance from stock parts.
The only magnets are the motor magnets. No traction magnets allowed. So they widen the front axle and add brass weights to the axle. That really stablizes the car. But the cars look odd because of this.
They buy better wheels, tires, axles, balanced armatures, better motor brushes, etc. All listed within the rules.
You can lower the chassis by adjusting the tire height. No extra down force other than a lower CG.
Fray racers blueprint the chassis, and take the luck out of having a good runner. Most out of the box T-jets run poorly.
My apologies that I can't give you lap times. You should be able to figure that out by watching the videos.
Yes the Fray cars are very fast with stock style chassis.
