  1. Race Tracking Your Supra - Information exchange

    How do you guys with manuals manage this? Just bring a big 2x4 to back into? I’ve just been shutting the car off and letting the fans run, but would prefer to let it idle for a few minutes instead. If I temp the rotors with a laser gun is there a temp where it’s safe to put the e-brake on?
  2. What did you do to your Supra today?

    Went for a drive
  3. Radar Detector

    R8 + Blendmount + Mirror tap in the Supra Got this Amazon mount/tap kit for my commuter car that is honestly fine, but occasionally needs to be tightened. https://a.co/d/00fHvoOI
  4. What did you do to your Supra today?

    @rwense Rapid Designs diff brace and oil change!
  5. Variable Height Lowering Springs

    Oh cool more choices to over-analyze! lol. Thanks hadn’t heard of those and the camber adjustment is great value. Looks like 3.5k/9k spring rates which is maybe too soft for occasional track duty? https://shop.bcracing-na.com/products/asp-series-19-supra-with-front-camber
  6. Variable Height Lowering Springs

    That’s awesome. Do you mind sharing the ride height settings/ other suspension mods and wheel/tires you’re running on track?
  7. Variable Height Lowering Springs

    Has anyone tried these? I can’t find much feedback on them but the design seems like a best of both for adjusting the rear and gaining clearance in the front.
  8. What did you do to your Supra today?

    First full day HPDE on Saturday. Think I’m hooked. Started hearing a weird clicking sound on hard turns toward the end of the day - turns out I still had one shipping spacer on each front shock (been there for 30k miles!).
  9. Dinan CAI Question

    My guess is it can fit more BMW models this way. If you run it without the lid it’s much louder but that kind of defeats the purpose.
  10. Dinan CAI Question

    Mine has a gap like that. It’s not perfectly enclosed
  11. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Actually ran OTS for one afternoon- long enough to realize it was trash compared to Adam’s tune. DME was out of the car less than 48 hours and I could follow it with an air tag the whole time. As you can all probably figure out from this whole thread, @ColonelAdama is awesome to work with and...
  12. Official STRATOSPHERE BLUE Supra Club Thread

    Looks great. What’s the wheel fitment? Are you still on the Dinan springs?
  13. Anyone running the Dinan lowering springs?

    Bumping an old thread but curious if anyone else got the Dinan springs or has updated feedback/ pictures. Considering these as an alternative to eibach z4s - similar drop but slightly stiffer. Is the drop any different on the MT?
  14. Coolant pump failure at 17k miles, 2023 3.0 PremiumAT

    Had the same thing happen when I got my car back from getting the mechanical pump installed. The bmw bleed procedure is automatic but kind of involved and will take a few rounds of it to get all the air out. I got the coolant from bmw and I think the car took like 2 qts of it (plus water so a...
  15. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Thanks I’ll try to follow those guidelines for the FF adjustment. Had a clean run today in map 6 and didn’t get the same throttle closure. Hoping I can just dial in map 6 and run that most of the time. Do you go with PID gain on 0 in all your maps...
  16. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Not trying to spam the thread but did my best to DIY over the past week and gave map 6 a try. I’ve had a lot of trouble with the app not saving settings and reverting back to defaults. I’m running the latest version of the jb4pro app. Issues are mainly boost safety not saving below 24 psi, and...
  17. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    adjusted a couple things in basic settings after spending some more time with the first post here. Can’t figure out how to get this to stop grouping logs, but the very last run in this one I think is the cleanest… Settings: Enabled ECU CANbus connection Boost safety 23 PID Gain 20 Shift Boost...
  18. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Just installed the new JB4PRO unit and took my first drive on map 1. Only a couple really clean runs in here. Had VSC on since it rained off and on during the drive. All runs were in 3rd gear and sport mode (not sport+). 2023 6MT JB4PRO X58 P358_V6 firmware Includes EWG and fuel pressure...
  19. Coolant pump failure at 17k miles, 2023 3.0 PremiumAT

    Had my 2023’s mechanical water pump replaced at 29k. Surprised at how many are failing at low mileage.
