Get rid of the tape -you need real drift tires, try out raikou's DXPE tires, they are inexpensive and slide and grip really good. In order to "switchback" you need a front one way and a locked rear and a tire with good slide/grip ratio. Put this combo together and you will be sliding and switching in no time.

you can get the tires here www.raikoudriftires.com

disclaimer: practice, practice, practice - no tire or modification will make you an instant drifter - practice required!
