Nice buy! The 325 brakes will be fine. Just get a good set of pads and some good fluid and you'll be fine. The "paint" is probably plasti-dip. I tried painting mine the same colour with John Deere blitz black and it turned out awesome... Until I crashed lol. Feel free to ask any questions-there are a few of us o. Here with e36 track cars now (my thread is in the Ottawa section).
