Hey whats up i got a few qs for ya. First is it better to have a tight or loose suspention in dirt oval track with a few jumps. What weight of oil do i use for oval tracks. Last but not least do i need top speed or acceleration. Oh by the way i have a electric rustler with a amber 17 turn double and a lrp runner esp if that helps any for the gearing part thanks guys i have faith that u guys will answer all my questions. :confused:
