Trike Drifting

found a new hobby today on its the Trike Drifting!!! hahaha yea i know its kinda old… i feel like buying a tricycle after work today at Toys R Us or wherever.. hahaha pretty nice angles with these Trike Drifting. where can i get these kind of trikes?? or do i modify by rounding off the rear plastic tires so i can slide and have the front wheel bigger so i can grip the front?? mang this thing looks fun!!
