If someone intends to use Harry's LapTimer https://www.gps-laptimer.de with his new GR Supra A90, he will be in need of the gear ratios.
Here they are:
1. gear 5,250
2. gear 3,360
3. gear 2,172
4. gear 1,720
5. gear 1,316
6. gear 1,000
7. gear 0,822
8. gear 0,640
rear axis ratio 3,150

I will use my Bluetooth OBDII sender Kiwi 3 of plx https://www.plxdevices.com/Kiwi-3-OBD-Car-to-Smartphone-Connection-p/897346002832.htm for OBD data. The OBDII plug is below the steering wheel, a bid to the left of the driver, no cover on it.
My 10 Hz rated GPS receiver is from Dual XGPS 160 https://gps.dualav.com/explore-by-product/xgps160. Internal iPhone GPS is too slow.
My old iPhone will run Harry's Laptimer and will be mounted on the cross beam behind the seats in the middle. I will use the selfie cam, because the normal cam has a strange behavior on the road due to a special lens which usually stabilizes the hand guided videos but results in poor recording quality when mounted in a car. The selfie cam does not have such wobbling lens and the video quality is good.
The iPhone is held by a RAM mount, the socket of which is adhered to the cross beam with this https://www.rammount.com/part/RAP-B-378U.
I used a similar equipment already a lot on track days.
