Also i already have the steel pinion set from HPI.
Thank you very much
I believe that coreless motors don't have a solid armature core where the copper wire is wound around. I'm only speaking from my experiance from taking apart a coreless servo. Other then that, its a brushed motor. A brushless motor has no brushes that contact the armature. Because of this, a brushless motor last much longer.
As far as speed goes I'll list the motors in order from slowest to fastest.

Graupner 300/Orion BB
Hand modified brushed motors
Brushless
The last 3 are pretty close in speed. I listed the brushless last because you can get brushless motors in various speeds. The fastest brushless motors will be give more top end then a brushed motor can, but may make the car undrivable. Also a brushless motor needs a special speed control.
