Default Girodisc 2 Piece Floating Racing Rotors Rear

Hey guys,

I recently purchased the Girodisc 2 Piece Front Rotors Ring replacement as my Fronts needs to be replaced soon.

Link here: https://www.girodisc.com/Girodisc-2p...Ti_p_5728.html

At the same time, I decided to complete the whole look and got the Girodisc 2 Piece for the Rears as well (because racecar) and so that I can brag to my friends that I had 2 piece floating rotors in the Front AND Rear.

Link here: https://www.girodisc.com/Girodisc-Re...Ti_p_5527.html

The Girodisc Rears weigh only 11lbs, which saves 7lbs over the Stock Unit (18lbs)

My initial butt dyno noticed a difference is the acceleration of the car with the Rear Girodisc Rotors installed.

I felt that it was slightly quicker and less sluggish than before off the line, especially from a dead stop.

The Rotors looks absolutely beautiful and the Made in USA quality is definitely evident

If you are looking to replace your rotors, look no further than Girodisc! #NoRagrets

So you no longer have parking brakes?

I think those rotors still use the internal area of the aluminum hat as the parking brake drum. Just don't drag the parking brake while you're rolling....

LOL the aluminum hat is not a parking brake drum. In effect, there's no parking brake.

We won't know unless we buy one, see a photo of the back side, or ask Girodisc.

It's not as if the parking brake drum is a high-wear part. the shoes only make contact with the drum when the vehicle is sitting still. I agree AL is not the right material, but the parking brake would still work pretty dang well with an aluminum drum, I would suspect...

That hat has very little contact with the drum brake as compared to a rotor that's designed for it. I wouldn't trust it to hold the car.

Looks like the parking brake is retained.

Thanks for sharing.

I hope to pick these up for my '19 STI when I do my first pad/rotor change down the road. I recall KNS posting that the Girodisc rears aren't possible for the 18+ STI because they would require a shorter pad and/or a lot of grinding. Looks like the DBA's are the only slotted option for the rear at this time.
