New DBA Street Performance Slotted Discs (T2) and matching Pads, fine for around town.
I was breaking them in, did a few 60-20 stops, a couple hard stops from 100/140 to 40 or so, all separated by around 3 minutes, followed by a very hard stop from 180 to 10. It was more than they could handle. Needed to cool them off, and until they cooled off they were spongy and required a lot of extra foot pedal pressure to stop the car.
For the way I drive, I'll be going a better brake system next time.
If you want an upgrade from stock for regular people driving, these are fine. For more aggressive driving, no.
Maybe they're still breaking in. The discs are now multi coloured from heat so either this was beyond their capabilities or I've over-cooked them before breaking them in enough 🤷♂️
