About a difference of V3 yellow and V3 Blue,
The yellow is good for use on the high grip condition racing track. A development concept is a car can flow on the heavy track condition well. We put our new technology in the yellow can. You can feel your car lighter even track became very high grip with yellow. In other words, This yellow can not give you strong grip on the low grip track.
The Blue will give just really strong traction on your rubber and foam tires. The V3 Blue is stronger then our V2 red before. This is our best answer for a parson who really need strong one!
You just may need to be careful to use this if the track became high grip condition. Because if track and tires both high grip together, It will sure happen car spinning or traction roll on the corners.
In between High grip and low grip, We recommend to use 2 time apply by blue and yellow.
Or We recommend you to blend blue and yellow to make your own special traction control compound.
Actually, This was our purpose since when we were making this last 2 years.
So now, You may have a best traction compound for high grip track and its yellow. Then you may also have a best traction compound for low grip track.
