You need abs tires all around and you can get them on ebay. Just search abs drift tires. Yea the Zip ties do make the car stiffer, but once you lock the rear diff, suspension adjustments are up to the driver and yes new battery made a HUGE difference
I just locked my rear diff, by adding the paper like you said, i had to repack it twice since it got looser after awhile, what kind of suspension settings you like? Do you lock the front diff? What kind of battery size is good?
