Brake discs GiroDisc or OEM BMW

Saves energy when braking. Its really satisfying to see the range go up when slowly braking downhill. This also saves your brake discs from wearing out fast, (just remember to use the brakes some times so they dont rust).

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.

Today I actually saw a car where the wheels had fallen off. I had to dodge a brake disc in the road lol.

Verdict - Preformed great, very pleased!!!!

Ever notice how BMW does not use cross drilled rotors. I think Porshe is also open about the fact they only use them for the looks. HMMMM

BMW OEM rotors after 4 years and 35k miles. Junk build quality now
