   The video did not load for me. What quarter mile times are you getting at the moment? Also at what terminal speed, In what gear and at what rpm are you crossing the line?

   a 2.4sec 60 foot is not good buy sum better tyres toyo r888 or yoko ao48 needed, best 60 foot i got on toyo r888 was 2.012 ,its all lost on the line on a fwd car so best tyres u can afford and maybe a limited diff
