Reviews of GiroDisc brake discs

I'd buy a set of Girodisc rotors. They will last 10 times longer than crap audi rotors.

Definitely approaching end of life. I wouldn’t have a safety concern just yet but you’re getting close. Go with Girodisc for your next set. They’re more expensive but they are amazing.

Reliability and safety are my main concerns right now, so I also have Girodisc rotors

Almost every car in our PCA club runs GiroDiscs, even the GT and RS cars. Never heard a single complaint, and love them on my C2 and GT3.

We are on our fifth weekend with our girodisc two piece rotors. Yes they are expensive, but they are worth it. They are so much better with heat management.

Follow up after my track day: The Girodiscs + Pagids were amazing. Tons of bite, and zero fade, plus plenty of pedal feel after two days of running hard at VIR.

I have had great success with Girodisc rotors this summer. I have been using Ferodo DS2500 pads for a few years and love them, but rotor temperatures would hit 800+ degrees after track sessions and conventional rotors, like Stop Tech, developed surface cracking and maybe a bit of warp. Girodisc rotor temps have been around 550 degrees after sessions this summer.

Verdict - Preformed great, very pleased!!!!

Update for all those following along. My brakes were the best they've ever been today - on a very, very hot day (feels-like temp over 100). I had a vibration with light brake pressure, but pressed on giving more pressure and found that as the brakes got more heat in them, and I went deeper into the braking zone, the vibration disappeared. All was well, but after checking the rotors, they appear to have developed cracks.

The limiting factor was tire grip Oregon Raceway Park (ORP), clockwise one day and counter clockwise the next, is hard on the brakes, tires and suspension with the hardest braking zones being downhill and the brakes did not complain both days. GiroDisc is definitely doing its thing and the HPA rear BBK is doing its part.
