Alright thanks for the response, would changing the gearing possibly fix the top end problem? Or is that when the overheating problem would possibly occur?
Follow the stampede gearing. It should be 86 or 90 tooth spur, 16 or 19 tooth pinion for the rwd. I can't remeber exactly, in 2010 or so I converted to 32p gears. If the motor, esc, and battery are cool, you can gear higher. In the winter you may be able to squeeze a few more teeth out.
As for tires, the more mass they have, the lower the gearing. Although the gearing dropped, the size of the tire will give it speed.
A stock bandit wheel, a stock stampede wheel, and a stock slash wheel will have different speeds on the same car unchanged. The bandit will be slowest, stampede should be the fastest.
The more aggressive tread pattern like proline masher 2000, they will run slower then a street style ttead or slick of the same size.
The bigger tires may lead to premature drivetrain wear depending on driving habbits.
Are these the 2.8 wheels?
