I'm setting up a spec car to run on a 115ft flat carpet oval and here are some of my questions

1. what spur and pinion ? the car came with a 128 spur

2. the front king pins are tight or should they move freely up and down?

Thanks in advance

what kind of spec car is this, if the king pins are tight they need to be nice and free, thats one of the keys to being fast. Alittle more information on what type of spec car chassis tires etc would be helpful to help you. Also does this car have to go by certain rules? thats very important, some tracks run spec cars with certain gearing rules.

It is the trinity spec car. I'll be running BSR green and silver RT front the rule book say 120 and 34 but the car came with a 128 spec motor batts and yes I will have to free up the front.
thanks
