4000 / 5000 series rotors

[dazsta]

Hi,

I'm currently using DBA650 rotors with rb74 pads up front, comp 2/9 (forgot which one) at rear with standard rotors.

I'm using AP600 braking fluid and have only had severe fade only once on the track after a ridiculous number of continous laps.

I'm thinking of upgrading to either the 4000 or 5000 series.

I wanted to know how these rotors perform, are they ok for street use with pads like RB74's?

Will pads like RB74's chew through the rotors? (does operating temprate of the pads or rotors play a part here? )
RB74's seemed to be very harsh on my current rotors.

Could you also recomend what pads would run best with these rotors.

What improvements would I see from my current setup?

Also what ballpark figure am I looking at for getting these rotors for front and rear.

Any help appreciated.

EDIT: Sorry, Car is a MY99 WRX, occasional to frequent track use and dirt use.

4000's for the front wills set you back about $250 each
5000's for the front will set you back $430 each

4000 not yet avail rear
5000 probably won't ever be available rear

Pagid RS4-2 front pads $400 set

Cooler running temps expected. Longer rotor life. Less chance of cracking.Great for street as well as track use.
