Much better than stock equipment
The stock rotors and calipers (with race pads equipped) were not providing enough stopping power for the Corvette Z06 on the Sebring raceway. The StopTech kit comes with street pads, so I ordered StopTech's SR32 race pads to use although the pad shape is a common one available from many different vendors. Regarding slotted vs. drilled rotors: The StopTech engineer said that drilled is for show; slotted is for the track. It's like I am driving a different car! Very happy!
StopTech BBK for 2005 G35 Coupe
The biggest 'flaw' of most 'Sporty' cars is the brakes, not for 'normal driving', but 'spirited driving'! I did a lot of research, before purchasing the StopTech BBK. One of the biggest reasons that I finally chose this BBK, is that it is a 'Balanced' system, balanced with your OEM brake system (ABS, etc.) The BBK has lived up to its expectations, although I don't have very many miles on it. AutoAnything had a VERY good price on the kit, which has now gone up considerably.Used PosiQuiet Pads.
