I had to replace all braking like the lines and everything so no noises in the brakes or anything, the tires are less then a month old.First mod should be what the car needs most. Are the tires at 3/32" of tread or less? If so, get new tires. Are the tires worn unevenly? If so, get new tires and an alignment. Are there noises, vibrations, or pulsations when braking? Fix the brakes. Are there fluid leaks? Fix that.
Once all of that is good? Driver mod. Go find a HPDE class somewhere, buy a helmet, and go learn to REALLY drive it.
