2019, GT, MT82, PP1, Magneride, Steeda Performance Progressive Lowering Springs, changed all fluids to Racing Hi-Pro Fluids (Brake, Diff, Trans, Full Sync Oil).
Beautiful day at Barber MSP. Fog delayed the start. About 49 Degrees F in the Morning, warmed to around 74 F by late afternoon.
Complete 4 - 30min sessions w/ instructor.
Stated with tires at 30lbs cold, let off more air as day warmed. Still TPS was showing 35lbs at the end of the sessions. Michelin Pilot Sport Tire on Barber’s new surface. Tires squealing around most all hairpin turns. Top G’s on force meter was 1.11. (Got 1.14G’s in July at Road Atlanta). I’m thinking I could have let out more air to target 32-33lbs hot for better grip. What do you all target for hot pressure?
Was hitting 102-103 mph on the two long straights. Ok I guess. Car doesn’t feel as quick when you are running with a bunch of other “fast” cars. Seems like it takes a long time for RPMs/HP to build-up.
For the Steeda Springs, could not tell a bit of difference from stock PP1 springs. Maybe they are a bit softer, which is going in the wrong direction IMO. Didn’t lower the car much at all either. That was probably a waste of money.
Near the end of the 3rd session car went into limp mode with a yellow engine light. Steady light. Not flashing. All temps seemed to be in the “green” according to the gauges. Only thing we could think of is that we accidentally left the air conditioning on. Diff temp was ok at this point as was coolant, oil, etc.
At the end of the 4th session, did get a diff over heat warning. Although diff temp was not in the red yet according to the gauge, and car did not go into limp mode. I think this was some type of pre-warning. We pitted on that lap. Gauge did show high diff temp. But was not yet in the Red. Had about another 1/4 to go.
