I will use LRP V12 4.5T and LRP SXX TC spec, I will run little bit indoor and out door. In accordance to LRP I will need a FDR around 9.5 - 8.5
I did then calculate out of the charts, I can use 23/116 & 26/116 That will be 9.5 & 8.5. I have heard some one say it's good to use larger spur??
So what spur size it's recomended for modify and stock, I will use 4.5T on modify and 10.5T on stock???
