Rotors
I did track day yesterday at Laguna Seca and on my way home brakes were chattering, think from heat and deposit on rotors.
.It is fine up to some speed but soonest you get serious about going you find all limitation of this car on the track. Suspension is not up to it, electronics start kicking in, transmission to slow shifting in manual, brakes smoking...etc.
You can have laugh tho when windows start coming up and seat belts tighten in middle of corner
