Faster Than FTE
How about the hot wheels training facility (HWTF) cars. I have bought a few and they roll really good. I raced them once so far and they stood up with the fastest cars we have.
If you're refering to 'HWTF' cars with ", then without nickel-plated axles. High Speed Wheels(HSWs) look like the photo below.

They also come in green, blue, yellow, black and white versions. I have a few of the white and reds.
Yes, it is HWTF. I have found them at toys "r" us in single packs. The yellow wheel trucks have been the fastest so far. I bought around 12 of them so far. They do seem to need a break in period. After 3 trips down the track my yellow wheel Baja truck was running with fastest cars. They are very lite. I will try adding some weight this season.
They stopped making the High Speed wheels back in 2012, the only year they were produced. They do mention Hot Wheels Test Facility on both packages.
Here is a list of the high speed wheels:

The Hot Wheels Test Facility vehicles are just standard wheels.

I think he means the Hot Wheels Test facility cars, I've never heard of training facility cars.
