Drag radials are a real big help....if you have excessive wheel spin. If your clutch is a little weak, hooking the tires up is the last thing you want to do.
I know I repeat myself but.............If you want to drag race...you need a different car. If you want to really love your Focus? go to the twisties. You can run with anybody there.
You ain't old enough to have that much to bitch about!!!
