Hello,

Vehicle is a 22brz, changes are brake fluid, pads (initial track days 2022 and 2023), camber bolts and rce sway bar (this year - 2024).

On the track days, during the end of long straight (110 to 120 mph max), during braking (about 1.1G), the rear end becomes too wobbly. I understand that with this level of braking, not much tire traction is available on the rear, but the feeling I have is that the rear is moving due to instability on the chassis, or going toe out during suspension droop or deflection on rubber.

Did anyone experience similar conditions? What are the main countermeasures? Add toe-in on rear (hide the effect)? Any suspension pick-up relocation (reduce toe-out)? Coilovers with stiffer springs (reduce droop)? Any other? Which one is more recommended?

Regards
