I think I should share some of the work that I did about 3 months ago on this car that we are going to make option parts on...and some idea about what I think it will make the SP1 handle better on outdoor....since we are not running indoor anymore until winter, so outdoor setup is what I am chasing after...

I will provide some data about using Pit Shumizu, TCS rubber, Tamiya stock rubber and Pardus rubber tires specification and setup on the SP1 soon. The only tires that I cannot provide info are the new RIDE, they are all coming with +3mm offset rim and that made the width way wider then 190mm that would not be legal in USA racing.
