Interested! (I was in the front rotor GB.)

Was Racing Brake also going to offer a rear caliper upgrade option as well? (I can't recall from the front GB thread, and I'm too tired to dig through the entire thing--assuming I'd even catch it if it was there.)

Now that we have released the light weight 2-pc rotor the rear caliper upgrade will follow. Updates will be posted in this thread.

Also I was in the front rotor GB. Please add me to the rear rotor GB. Is there an ET-500 pad option?

[Finnegan]

If anyone is interested in the option of a larger sized rear rotor, please indicate that.

I think RB may consider offering a rear upgrade ring in the 348x26 size (in addition to the 328x22mm size) if there's enough interest.

This would be similar to the PU caliper upgrade + BBK offered on the front rotor GB I believe.

[RobMCoupe]

I've been waiting for the rear since the GB for the front. Please add me to the list.

[RobMCoupe]

Minus pad if there is an option. I will decide on the pads when I make my caliper purchase.

Thanks.

RobMCoupe is added to the list minus pads.

[cymek]

What is the cost of the et-500 pad option?

[Finnegan]

Also interested in an ET500 option.

[kalare]

RB, with the additional 2mm thickness...is the rotor still centered where the OEM rotor is centered? In other words, is the 2mm added split between 1mm on each side or is it 2mm added to only one side?

ET500 Option

Upgrade to ET500 brake pads for $20 more, new total w/rotors would be $758.

1mm to each side was added keeping rotor centered between OE caliper.

This can only be possible with our patented "center mount" design - Rotor thickness varies symmetrically so the offset remains unchanged, unlike traditional surface mount it would have added 2mm offset towards outboard.

I notice you charge an additional $180 for blue color calipers. Can you explain why the extra premium for blue compare to black/red?
