if you know who painted the car they should be abel to do it, also while ur at the wreckers look for ae82's and suck and if they have colored springs big chances they are lowered ones, you could grab them and keep your standards if you got defected or was selling the car to some one that wanted it standard height,
i would recommend against tinting the tail lights, in my opinion it looks cheap and easily detectable, just polish all your lights up and it will look overrated.
also you could just get some springs and cut them and keep the ones in it in case you need to go back, i like cuttys and theres nothing wrong with them imo
