Info on nitro rustler pro 15, please
 

Hello,

I am new to cars. I picked up a nitro rustler pro 15 Saturday for my son.

The seller, nor I know the model number. It must be old as they don't sell the 15 anymore.

I would like to upgrade the front wheels to bearings because it has bushings and a lot of slop.

Does anyone know what I need to buy to make this upgrade? Do I need new wheels or can I buy a bearing kit that has the spacers and bearings?

Is there a way to get the car higher off the ground?

Thank you.
