Carrera Digital Car, jerky

Hi there!
Here's some issues I've had purchasing a second hand Carrera Digital Nissan GTR.
Here's the issues.
The bearing on the left rear was really lose, I know gluing it down will sort it out so I'm pretty cool with that issue.
However what I'm not really pleased from the previous owner was that the car was really slow compared to the current Carrera cars coming out. It kept stuttering and stopping halfway during the course.. I changed the braids and opened it up a bit. Cleaned up the contact points as well. However it isn't running that great... I'm playing with two ideas. One is to not give up on it and try to push that chassis to get it running decently or the second is to get a Slot.IT chassis on it and ditch the original chassis.
What would you do if you were given the choice? :) :text-thankyouyellow:
