there r so many variables in drifting. cost cat be put on a single dollar, i can eat up 2 brand new tyres in a couple of runs, but i have 350rwhp+ it depends on the speed u drift at and the corners, a diff that locks is a must either a 1.5 way or a 2way, stiff suspension, braces every where, any way u can make the car stiff do it. its not all ways the best to use thecrapiest tyres u can get as u need front end grip as well as grip in the rear, (as long as u have the hp to spin them) its all about making the car that appears to be out of control, in control. the cooling systems take a pounding due to the high rpm and slow car speeds. oil coolers are a good idea to take the load off the cooling systems.
