Dual rotor upgrade?

Braketech Iron
4-pad Brembo
CP-211 pads
13mm Brembo master

did the 749/999 caliper go straight on?

how do the iron discs fare with sintered pads do you know?  i've always had the ferodo people here put me off the cp211 for road use.

Caliper went straight on.

Mated with a new Brembo Snowflake rotor that then lasted 24k miles of 70% freeway commuting, 20% rural and fun riding, 10% town riding.

The above pictured Iron rotor went on less than 3k miles ago, with new pads.

My S4 with dual Irons ran Platinums in the OEM 2-pin calipers for 19k miles, then CP211's in 4-pad calipers for 22k miles.

I'll check thickness, but they're not worn much.

I'd have used Platinums in the 4-pads if they offered them.....

The CP211's are a bit less grippy when cold, but nothing dramatic.
A couple stops and they're fine.

Just a quick question without threadjacking . . .

I have the opportunity to get a pair of 4pot/4pad 999 calipers, how much difference will it be against my 2pad/4pot calipers?

I have the Brembo RCS 18-20mm brake master

I would say definitely more power, but I've not run the same pad compound in both, so YMMV.

So you would say " go for it?"

Yes!

You will need a different brake line, as the inlet position on the 4-pads is different.

Seems like too much braking power for a 620. And a really limited/expensive selection of pads. Then again it might work really nice with the RCS.

beat you to it ..  . I am offering $150 for calipers + lines  . . . guy said yes . . .
