I ran a 13" for about 2 years. You will notice very heavy effort at low speeds. You have tiny and crappy BFG's so it might not be so bad. Forget that with 245 BB's. Radials would be better.
Your alignment is not 'close to standard' and not helping turn-in effort. Caster should be 4 1/2 - 5 degrees and camber around - 3/4 degree. Toe should be closer to zero for better turn-in too. Your fronts must get shredded pretty quick with those specs.
