Do the NQSBBK perform much better?
Better than what? Better than GTi brakes?
If so, the answer is YES!!
NQSBBK was one of the best things I ever did to my Golf.
Even though I didn't have big power, the handling was sorted and you could drive the car quickly. This was possible by the much more intuitive, progressive, powerful brake setup. Because they are lighter the car handled better also.
