I have been experiencing a progressively worsening high speed, high heat braking shudder that MB refused to warranty. They used my vehicle modifications as a pretext for refusing the warranty claim. However, I wasn't overly pissed off because I wanted to install lighter rotors anyway. I ordered Girodisc rotors and the Girodisc SS pads for the front axle of my E63. The Girodisc front rotors are 7 lbs lighter than the stock iron rotors and, unlike the stock units, are full floating. I am very impressed with the quality of these rotors compared to stock. The SS pads have more bite and are supposed to be able to withstand much higher temperatures. I am experiencing no squealing or noise that often accompanies higher performance pads, but they do generate a bit more dust than the stock pads. Now that I have tried the fronts and found them to be superior to stock in every way, I am ordering a set for the rears as well. I purchased for 12% off retail which seems to be the best deal available on the Girodisc products. The install is extremely easy for those of you who are DIY'ers. You will lose the factory electronic wear sensor with these pads. Girodisc also makes a very nice caliper spreader that I highly recommend as well.

Thanks for the review, useful info

PeterUbers

Great review ... good to know they are out there. Hope they hold up over time and prove to be superior ongoing

Are these cheaper than oem parts?

BerndV

The rotors are nearly half the price of the inferior OEM rotors. The pads are about the same price.

chiromikey

Thanks. Please give us follow ups as they wear.

Yes I would be interested also.

Can those prices on the rear rotors be right??? Does that maybe not include the aluminum hat?

gaspam

yes they are correct (oem are one piece)... you can even get them form MB direct for only a few bucks more

or non-oem even cheaper

i have them on my 211 Wagon and love them - did alot of research and after talking to Girodisc Direct and ACG I was won over - have had them on for about a year now and love them - the only downside is they take 5 mins to warm up on a cold day - other than that Girodisc are the only rotors ill be putting on my AMG in the future -

Closest to buy was RacingBrake but alot of bad press on failure rate -

PeterUbers

what does "5 min to warm up" mean? Does that mean they squeal in those early cold minutes?

that would be a no go for me

BerndV

No warm up needed. They perform just like stock when cold, zero squealing. I ordered the rears today from Competition Motorsport. It seems that Buybrakes is no longer offering discounts on Girodisc products. I got 12% off from Competition Motorsport.

I have this set up as well F + R on my W211 for a few months. So far no squeaks or squeals braking feels better (akebono pads). It's cooling down so I'll monitor colder temp performance.

The guys at Girodisc made for a smooth and informed purchase.

A few pictures along with a few accompanied words will be greatly appreciated.

BerndV

The link you provided shows a price of $629 per front rotor. That equals $1258 for the pair without shipping. Your Girodisc link shows MSRP. My Girodisc fronts were $924 for the set including shipping. The rear OEM's are junk. The entire disc is one piece cast iron including the hat.

Stereolab42

I have the Girodisc rotors as well, with the stock brake pads. Zero problems.

gaspam

where did you get them for $924 shipped?

and on the fronts shipping, its free on the link i provided...ecs will also ship the rears free

peter asked what the oem cost was and i provided it for him... max anyone should pay for OEM front /rear seat is ~$1600 shipped.... girodisc sets are $2300 from buybrakes.com with $50 off coupon, and $2350 from ams

BerndV

I bought the front discs, front pads, and the Girodisc caliper spreader for $1400 shipped from Buybrakes.com. MSRP for all three is $1600. That equates to a 12.5% discount, which means I actually paid $918 for the rotors. I just ordered the rear discs and pads for $1300 shipped from Competition Motorsport. MSRP is $1480. That equates to a 12.2% discount.

otakki

Are the Girodisc rear rotors more expensive than the Girodisc front rotors? That's what the links show.

BerndV

Yes

a100steaksauce

Looks like it for this application. They are 360mm rears considering.

otakki

For the initial purchase of Girodisc, the rear is more expensive than the front. On the other hand, replacing the Girodisc rear rotors is cheaper than doing so for the front rotors.

BTW, I think the oem front rotors made by Brembo MY2012+ are not true 2-piece but rather 1.5-piece where the hat cannot be separated, right? On the other hand, the ones on MY2010&2011 are true 2-piece even though you cannot buy just the rotors.

BerndV

FYI for those of you planning on ordering the Girodiscs for your Benz; the discs are available slotted and drilled as well as slotted only. Girodisc highly recommends against the drilled but they make them available for cosmetic reasons only. Also, if you order their pads, make sure you order them with the wear sensor. My fronts came without sensors because Buybrakes never told me they were available with them. However, Competition Motorsports sent the rears with the sensors which is how I discovered that they were available that way. I have over a thousand miles on them now and they are absolutely awesome. Great performance at triple digit speeds and zero noise at any speeds.

otakki

Is the price for the pads the same with or without wear sensors?

BerndV

Same price.
