They only show the front but no rear, did they take it off?

Anyone order this Giro Disc 2-piece, I am interested in shaving 6 lbs in the front.

Thanks!

A quick update for you all:

All these 3 are dual drilled (confirmed with Girodisc via email).

A1-007 will work on the front 100%.

They cannot confirm the rear but both are dual drilled.

Girodisc confirmed the A2-095 is dual drilled so it should be fine? I hope?

Hey guys, I actually found another option for the fronts at least. $700 for the fronts @ 17.1 lbs, so not as light but still decent weight savings.

I got the TRD/PP Brembos for a fairly good deal and swapped in the fronts the other day. Found out I need to do something about the dust shield in the rear so the rears are still stock but I weighed the calipers and rotors (I believe they are the same for all non-Brembo models)- non-Brembo weight first, then Brembos:

Front rotors: 16lb, 15oz / 22lb, 12oz
Rear rotors: 13lb, 1.5oz / 16lb, 13.5oz
Front calipers: 13lb, 15.5oz / 12lb, 1.5oz
Rear calipers: 6lb, 15oz / 5lb, 15oz

Does anyone know the disc width and disc airgap for the PP Brembos Front and Rear? I want to upgrade the discs, but I want to make sure that they are the same.

Girodisc to the rescue!

Confirmed Girodisc fitment from Girodisc themselves!

I reached out to them (finally) since I wanted to shave some weight down on the rotors when I replace my brake pads later this year.

Front rotor replacements: A1-007 5x100
Rear rotor replacements: A2-095 5x100 and 5x114 dual drilled

They also finally made a section for our platform with performance package/TRD Brembo’s!

I hope this post helps out anybody in the future

Probably stick with 1-piece rears for now...
Give me DBA Slotted Rotors + more track time

Maybe ask them to update the photos for the product page of A2-095 while at it?
The photo clearly shows a rotor with a 5x114 hole pattern, not dual-drilled.

Look great, work great, 12 lb. lighter, $$$. 20+ track days on them, fair amount of heat-checking but look to be good for ~8-10 more before new rotor rings?

Any obvious thermal performance difference vs OEM? Vs Centric Premium? Photos?
Any "clicks" when street driving?
