This was track day #6 in the BRZ at Laguna Seca and the problems only started showing up when my instructor had me braking harder.
Time to look into new pads! |
I am amazed you got SIX days out of stock pads. If you were hard on them, they'd be smeared in a day. I run Carbotech XP10 pads and have no issues with my brakes at all.
The wheels get very, very hot, but are most definitely not deforming at the hub so much that the caps fall out, as someone else suggested. The tabs get soft when they are riding in a 200+ degree wheel.
One thing I did preemptively, based on experience with my WRX, is replace the stock lug nuts. I would get stripped nuts every time I hit the track with that car. Yes, I own a torque wrench. No, I did not cross thread them. They are of terrible quality.
My Primacys are working well and have several weekends on them. Coming to the end of that road, though...
Oil cooler goes on this week, as I would like to see temps stay well below the 270 max I am seeing now.
I really don't expect anything else to fail at this point. I just want 17x9 wheels and stickier rubber
