    Car only has 100%. Can’t steer 60-% and brake 70%. Has to add up to 100
  2. Race Tracking Your Supra - Information exchange

    The trap w spl in front is you can start off w too much adjustment and the tie rods no longer ride under the nice designed in arch on control arm
  3. 0W20 VS 5W30 VS 0W40 Motor oil for track use

    Big difference in oil specs if really racing (not just a couple track days) and normal- even spirited driving the 0-20decision was mostly due to emmisions goals. Nothing to do with “specs” so Many people over think oil Weights If not racing there is zero reason to run anything other...

    G-force nighthawk series is good.
  5. To the red supra who flashed me while getting onto 309

  6. Several HPDEs in, looking into mild track upgrades

    Even though i know they don't, they seem to act like solid axles in the turns still. I am amazed following them on the track how the rear end seems to jerk- not smooth rotation.
  7. 0W20 VS 5W30 VS 0W40 Motor oil for track use

    yes disc batt, check all connections, rec batt and try again. look at all the pins too for something bent or missing.

    def connections. you should also always do this with battery disconnected. If connected and the connection isn't lined up perfect, it can short across pins like what I am guessing and the computers on these BMWs are SUPER sensitive.
  12. Several HPDEs in, looking into mild track upgrades

    Man you are so right about the blue group! We should/can start a "tales from instructor land" thread. But last HPDE, Head instructor pulled the ENTIRE blue group in for a talk. We focus on education and improvement- and their lines and passing were absolute dog crap. Also been really...

  15. Several HPDEs in, looking into mild track upgrades

    I will add something possibly controversial... The Supra is the WRONG car to learn racing/tracking. It is too fast and has too much torque. In a e46,miata,frs if you blow a corner you lose so much momentum it is really obvious and MAKES you concentrate on Track craft, braking, apexes...
