You are loosing precious time by asking this on the Forum
By the way, 100% stock 1M is not what a 1M should be to begin with, correct the few weaknesses of the stock car with a few careful-tested and approved mods to enjoy it to the fullest (a nice exhaust w/stock dps, good stock size tires, CDV delete, camber plates for a bit more camber up front and a few cosmetic bits of your selection to make the car look fit for your taste etc.) These won't cost you a fortune and will be easily returnable to stock. None will have any downsides whatsoever, few people will ever notice that your car is not fully stock too.
Take the VO too!
