What motor and what size of track are you going to be running on? I don't think you will need spurs that large if you are running brush-less. A 106 is the largest I have ran. As for pinions, that depends on motor, track size, and speed control. For the non timed advance speed controls like GTB you will need much larger pinions than say a Tekin Rs.

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???

The larger spur will allow to adjust ratio at a finer rate, and it moves the motor a little more forward which takes a little weight off the rear axles, so in theory would give a bit more steering. For those ratios I'd recommend the 116.
