I was all excited about these until I realized there are few to no race compounds available for them.

The stock brakes with respect to other cars is not that heavy. Given that the AP Radi-CAL brakes are extremely large, the weight gain is partially acceptable. It really is a matter of what one wants.

True. I assumed bbk's saved weight. I suppose my assumption was based on no real knowledge though lol….

either way the kits are NICE. Good luck!

Most bbks don't save weight. The increase in rotor size offsets what is lost in the other components. The ST kits are barely lighter than the OEM parts. You gain increased thermal capabilities and stopping power. For taking on the few pounds or not losing much depending on what you're buying. There's always carbon ceramics.
