I use this shock oil with the Yeah Racing 55mm damper set combo for my TT-01 and my TL-01, and I get a much smoother ride than with the standard friction dampers.
This product is easy to work with, and provides a lot of value at a very reasonable price. You can get it in a lot of different viscosities, and at the low price, why not get a few different viscosities so you can set up your car to suit any tracks surface. I surely recommend this product to everyone.
