  1. Laguna Seca with Yokohama V601 tires

    Well NT01 is already a 100TW competition tire. That's not something I would like to put on a non-racecar. I have a few friends use NT01 so I know they are quite capable. My friend who drives a stock power F82 M4 with NT01 and factory suspension can do 1:41 at Laguna, which is fast but still 3-4...
  2. Laguna Seca with Yokohama V601 tires

    They don't have OEM sizes. For handling balance reasons, I prefer to stay with factory sizes for now. For NT01, the grip level is close to RE71R, which will definitely overload the factory suspension. Conti Extremecontact Force seems to be 50USD more expensive per tire than RS4. Well if it last...
  3. Laguna Seca with Yokohama V601 tires

    Thanks for your feedback, I just ordered V601 tires for my Supra. Will see how they perform. I am not intended to change tire sizes as well. I think the overall balance of the car is great (the car feels like a more powerful 86 on race track in its stock form) and changing tire sizes will...
  4. Laguna Seca with Yokohama V601 tires

    I think you are right they are not track tires for sure. But I feel they might be very good candidate as practicing tires like the GT Radial SX2 tires on 86 twins (not super grippy but have lots of feedback and consistency). I hope I could use Hankook rs4 tires on my Supra as I really like...
  5. Laguna Seca with Yokohama V601 tires

    I am very interested in these tires. I am very unsatisfied with the consistency of the OEM PSS tires. The grip drop dramatically when overheated. They also loss grip(heat cycled?) just after 2 days of track driving even though they have decent amount of tread. And the side walls are too soft...

    I see. Thanks for the reply. I am not aiming to improve overall grip since I would probably stay with factory suspension for a very long time. The factory suspension does not work very well with high grip tires as the spring rate is too low. The main reason I am considering a separate wheel tire...

    Does the OEM+ (18x10 ET30, 275/35/18 square) setup causing any rubbing issues with factory suspension and alignment? Does it make the car much more lean to oversteer?
  8. Carplay has disappeared

    My carplay disappeared at around 3:34PM PST as well. I think it is related to BMW servers. Last year there was a big BMW carplay outage if you search the news.
  9. Brake fluid liters?

    I used 1.5L brake fluid when I replaced mine in the shop.
  10. Clicking/Ticking noise coming from driver side.

    I have same issue. I suspect it was the bad bearing but after digging into this. I found similar complains on m3post: https://www.m3post.com/forums/showthread.php?t=146591&page=3 Apparently the noise coming from the 2-piece rotor. Not sure if Toyota is willing to replace the rotor under...
  11. Black MKV from Qatar Track/Street

    I experienced the same thing on track. It is quite annoying and I don't have a good solution when I found it. I am surprised this issue was not discovered and solved during development phase since it was heavily tested on track.
  12. Spongy brake pedal on Track

    I see, thanks for sharing your experience. Did you short your brake pad sensors, I found them very annoying if I need to change the pads often for track days. I am wondering if there is any bypass device for that I can use on this car.
  13. Brake bleeding requires dealer?!

    From what I see in the repair manual, you can bleed the fluid without special computer. But for newer BMWs (including this supra), it would require special computer to plug into the ODB to trigger the ABS pump to cycle the fluid from ABS unit out. I did that at a shop which primarily service...
  14. Spongy brake pedal on Track

    I brought my Supra to Laguna Seca racetrack last weekend. The car felt great on track without any engine cooling issues but I experience some issues with the brake. I already heard the OEM brake pads do not work great on track driving so I changed to RBF660 fluid with CSG Spec CP pads on both...
