  3. Black Stone Report

    Picked up the car on Friday and was at the track on Saturday. An oil change at 1000 miles after the first track day.
  4. Black Stone Report

    Here's my oil analysis for Castrol 5w-40 after 400 miles at Road Atlanta. Looks like this car doesn't care what kind of oil is in it.
  5. Brake pad swap.....

    The backing plate is glued on to the brake piston from the factory. Just use a pry bar and pry hard. You can't break anything. Might help to put a towel between your pry surface so you don't scratch the caliper.
  6. Break-In Period Driving Habits

    I was literally at the track the day after I got mine. Modern cars don't need a break in. Oil analysis came back with lower than average metals in the oil.
  7. Black Stone Report

    Here's another oil analysis. My engine is all stock, and about 200 track miles on this oil. I'm going to put Castrol 5w40 (BMW LL01) in it for my next few track events and then send in a sample again. Seems like this engine might not care what kind of oil you put in it.
  8. Brake upgrade options 2020

    That's what I'm saying. You won't find anything that less dusty than stock pads. Where do you think all the friction material goes when you wear down pads of this size?
  9. Brake upgrade options 2020

    The stock pads will be the least dusty if that's what you're looking for. You push back the piston the same way as any other BMW.
  10. Will RPF1s fit over the brakes?

    I'm literally at the track every weekend. I need some cheap light wheels that I won't feel bad about bending. I don't think they'll fit over supra brakes if they don't fit over STI brakes.
  11. Anyone have pictures of factory pads for Premium?

    taken from Centric's catalog for the Z4 m40i
  12. Is the 2021 getting new iDrive?

    They are not. Reviews will be released May 13.
  13. Will RPF1s fit over the brakes?

    Anyone know if the 18x9 Enkei RPF1s will fit over the front brakes? They're the correct bore size and bolt pattern.
  14. Are there any 3D printed wind deflector files available?

    Here's one for the 981. https://www.thingiverse.com/thing:3501921
  15. Brake upgrade options 2020

    What fluid do you have? I've found nothing bad about the stock lines as long as the fluid doesn't overheat.
  16. Carbotech pads are great

    Recently took my A90 to Atlanta Motorsports Park for a track day (with Jzilla), and the Carbotech RP2 performed amazing. This is the only non stock component other than RBF600 brake fluid. More than 200 track miles in one day, back to back 20 minute sessions, and there was absolutely no fade or...
