umm well I've never heard of niftech, so i cant comment on its greatness or lack thereof. Make sure the tires are very clean and have no foam tyre particle buildup or "rubber shifting" going on. First clean them thuroughly with motor spray and a paper towel. Then after they are very clean and have a nice shine to their surface, apply traction compound to the inside half of the front tires.

Let the compound soak in for 10-15 minutes. Wipe them off and go for a test run.
Oh and try a different set of tires.
