Took the car to track yesterday. This time I installed the H&R springs with 18 mm spacers all around. Re-aligned the Supra after the ride height drop as it gained more camber.
It was interesting to see how it will affect the feeling on track compared to the stock setup from last track day back in Sep.
Ambient temperature was 66 F (92 F last track day)
Max speed on the straight was 135 mph last track day compared to 138 mph, so the car is much happier in the cold and you can feel it.
Not only was the car faster on the straights, now its faster everywhere. I can carry more speed in corners and it felt more stable with some understeer in few corners, however there is still some body roll. The H&R springs helped but still it can be a bit stiffer. Also no limp mode this time!! Max oil temperature was 236 F during a full 20 minuets session so I had the chance to do more than one hot lap this time.
Considering all the above the car was 3.3 sec faster than stock! To do 2:21.6 around Losail is very impressive for a car in this class. I am confident now that it can go high 2:20 as is with a cleaner lap.
To adjust tire pressures without interference from the traction control I had to keep the electronics happy. Staring with opening the vehicle states and going into the tpms page and setting all options to others and then calibrating the new setup with the new cold pressures. I heard different Supra owners facing other traction control issue when altering the ride height with aftermarket suspension. I can say running H&R springs with the lowered ride height, I did not have this issue.
Only issue is that even with the traction control off you can feel the stability systems interfering under hard braking and turning. Hope to find a way to completely disable the traction/stability control. Back when I had my Toyota GT86 the pedal dance was used to disable all traction/stability systems. Wish there is something similar for the Supra.
After three 20 minuets sessions this was the condition of the rotors. The car had stock brake pads and factory brake oil. Can someone tell what happened? Cooked? Pad deposits?
For next track day I will be installing CSG C2/CP pads with brake fluid.
