  1. Parking brake adjustment issues

    There is a parking brake adjustment procedure. ie don't just crank down on the nut randomly.
  2. Parking brake adjustment issues

    Yes, the parking brake mechanism in the caliper screws out the piston to account for pad wear.
  3. 2015 right rear brake noise?? HELP!!!!!!!!!

    Also pull apart the bolts and boots, one caliper bolt on each side has a rubber bushing on the end. Make sure all of these parts are clean and well lubed so the caliper slides on them freely. Make sure you do not have rust on the caliper bracket where the pad shims locate the pads. You should be...
  4. Gen 3 spark plug debate??!

    The 548's will work but the 589's are what is in G3 Coyotes due to the potential for higher combustion temperatures with DI and compression. Not really certain how different they are in actual heat range. Information is spotty.
  5. Red Loctite on Caliper Bolts W715623-S439 4X

    Those come right out, I would just use some Blue Medium Strength on your existing ones and save these for when you need them.
  6. GT350 Track Day! First time at Thompson Speedway with POV Footage

    I think you are thinking of skid pad...not a place were you can carry 3 digit speeds.

    Recaro's don't do much better for XL shirt wearers.

    Came here to say that, my knees take a beating holding me in the seat at tracks like Thompson.
  9. GT 350 Brake Question

    Really can't go by photos online, they haven't been cross drilled since 2018-2019.
  10. 2021 GT rear brake options....

    You have to hold it down for a while to shut it "off" but it's never truly off. Running track mode is leaving everything on, it just allows more yaw.
  11. 2021 GT rear brake options....

    Wilwood offers a rear kit that is around $2500.
  12. 2021 GT rear brake options....

    Traction control off doesn't mean the Stability is off. While it will let you spin the tires, it still works very hard to prevent you from hitting a tree in the background.
  13. 2015 right rear brake noise?? HELP!!!!!!!!!

    But you can get the pedal to vibrate under hard braking on the street (panic stop)? Brake pads usually squeal, not the sound you recorded. The sliding rear calipers typically make most of the noise with any performance compound and swerving usually flexes everything enough to push the pads away...
  14. 2015 right rear brake noise?? HELP!!!!!!!!!

    That does not sound like a brake rotor/pad issue. Have you tried swapping wheels and tires around? You have zero ABS lights, you can still get abs to activate etc? Something sounds like it is not tight, and when you apply the brake it is forcing everything back into position. I'd look for...

    Yes, the designer tried to take advantage of the landscape. There was a section of flat track I carried so much speed (90mph) a stock S550 drifted 4 wheels and if it went bad it was pine trees. Lots of fun.
