Hi All

It is time to replace/renew the brakes on my SL500. I do Autocross, so I am looking at an upgraded set-up.
What is a reasonable priced modification? New discs "slotted"? Or should I stay OE?
What is the better/Best disc? Zimmerman, Balo, ???, Please advice.
Also, what are the better Pads, minimizing dust.

Thanks
