I use this on those Tamiya slick tires that you get in the TT01/TT02 kits. It makes the tires grip much better and will you give an edge in club racing. Tires make a world of a difference when it comes to racing and preparing them properly will make sure that you have a good running vehicle. Always remember if you can't put down the power you have efficiently you wont be fast and quick! Highly reccommend this stuff over the HUDY version.
