Advice for tire pressures: Eagle F1's on track?

SONOFEMERY · Nov 11, 2024

I'm tracking my Emira this Friday at Streets of Willow. I have sports suspension but with the Goodyear Eagle F1's. Curious if anyone has experience with this and if you lowered tire pressures at all to increase grip on track?

Also here's a good picture of my Emira up in he windy roads of Malibu, where the car is truly in its element.

I have the cup2 and landed at about 27/30 psi after coming off the track. Good luck!

The eagle f1's are pretty squishy and i got a lot of side to side motion in braking. I'd actually run them a bit higher than stock pressures to keep them a bit firmer. Would start the car at 33psi, each session when the tires feel like they no longer have grip, look down at current psi, and bleed down so your peak pressure is 1-2psi lower than your fall off point. good luck!

Track day over now, car felt great and tires felt great. I found the best pressures were actually stock recommended - 29 front 31 rear (cold). Below it felt too soft on corners, above lost grip. Again, this is for the GY Eagle F1's. Will be replacing with Cup 2's soon.

Found aiming for higher hot pressure around 36-38 they started coming good. The F1s I love on the road but still disappointing on the track.
