Will it look funny if all I can swing right now is the fronts? I don't think I see too many people with mismatched rotors front and rear.
but I’m bias of course!
You still have the original machining marks !Well here is my Eradispeed front as of today and 6-7k miles w/Z26 pads. I don’t track. Just street n occasionally strip. I have no complaints (or cracks).
Those appear to be fixed 2 piece rotors, not floating. You have 2 different materials with different expansion rates which I would presume is fine unless you get them hot. That puts a lot of load on the rotor fasteners as the two pieces try to expand but are bolted together and both components need to flex to remain together.OEM on the rear with two piece on the front shown below. Looks good IMO
I went with Brypar two piece rotors on the front and left the OEM on the rear… I think it looks fine and there’s no issues with braking. One big issue that some people can get is when they upgrade the rear rotor and caliper it can change the brake bias (which is bad without other considerations).
My rotors are very similar to the Girodisc two piece rotors and they save about 5 kegs of rotational mass per side. I didn’t worry about the rears as I was only going to save around 1 kg and the saving was a lot closer to the hub so it would be next to no change in dynamics.
On track it’s the fronts that take the brunt of the abuse and I think it’s probably due to my driving style (hold on and don’t die).
the main reason for my upgrade was that the OEM rotors were seen a lot more when I changed my wheels. I couldn’t stand looking at them
For reference, I weighed the OEM rotors and compared it to the replacements. Below images show the differences in kilograms.
Thanks for this Ben.OEM on the rear with two piece on the front shown below. Looks good IMO

I've run Powerstop drilled and slotted for two years with Z26 pads. Zero dust after bedding the pads per instructions. Everything works great and didn't cost a fortune. If I were tracking the car a lot I'd have opted to spend more. Pads equal to or better than stockand as I said no dust.
not really to be honest
, but the wheels I certainly did. It seemed a lot more nimble.
Good man! Functional is the way to go.
You’ll be happy, I’m sure. Buy once, cry once.
Yeah except you also cry every time you replace the rotors to the tune of $850 for the replacement rings.
True, but you do that a LOT less often than with Baer’s, or the other cheap alternatives. Running stocks/cheaper alternatives doesn’t make sense if you use your car hard.
Those were the sports correct? Not the EradispeedYou’ll be happy, I’m sure. Buy once, cry once.
On the S550, I made the Baer Sport mistake, figured since they were $600.00 (fronts) they’d last a decent while. 2 track days and the cracks came quickly.
Yanked them off and went Steeda 2-pc, which worked excellent.
I’ll be ordering the Girodiscs for my 911 probably tomorrow, after hours of research the past few days.
