Now Girodisc are cheaper by 200 or so, at least for the fronts assuming I"m buying pads all the way around anyway. Racing brake says they are made from Harder Iron so I'm assuming they will wear better but haven't heard anything about the Girodisc in that regard. But 1050 for both with free shipping is tempting.

Well if it's the price that's pulling you in, that's totally up to you. I haven't seen much feedback on girodisk. Being that RB is $200 more, which includes brakes maybe you can call and adjust price since you don't need brakes. I have seen lots of great feed back on RB rotors.
But from what I have read and what I am experiencing RB rotors are worth the money.
Just my opinion. But search feedback you will find lots of it. Good luck
We have been using and selling Girodisc rotors on our AMG's for years now with absolutely no complaints or failures.
I've personally had sets of every single one of my AMG's and have nothing but positive things to say.
They are fully servicable if you ever need to change the rotor disc, they weigh significantly less than OEM equivalents, they are correctly vented, I've tracked them, bite and fade have been very satisfactory when paired with an appropriate pad compound.
Let me know if you want some pricing or a package deal with pads, I would be happy to help out!
RacingBrake is the number one brake option for our cars. They use by far the hardest steel alloy, and they have a patented cooling vane design that keeps the rotors cooler for longer. They can take extreme abuse. Don't let the price fool you, there is a reason why they are more expensive, they are worth every penny
do some research on RB Failures - i went with Girodisc and absolutely love them - +1 to what Tal says - and they look as sexy as rotors can look - if you know what you are looking at
Had the Girodisc rotors installed on my 2015 E63 a few months ago. The car brakes about the same as the stock rotors, but the weight saving is huge. Along with my forged HRE wheels, the combined 20 lb unsprung weight per corner makes the car feel more agile, like it is a few hundred pounds lighter.
Tal was extremely solid to deal with and the parts came right away. Thanks Tal!
I went with RB And their pad set up and I have never had any problems with them, I'm about to increase my front rotor size that RB offers for the e63! This company is always finding away to better their product and I love that. I always said I would love to have a bigger rotor in the front and they have it. Win win for RB
Racing brake is definitely superior and can take unbelievable track abuse (way more so than giro disc). I have never had a single issue with them and I would argue their brakes are even better than Brembos 2piece rotors themselves.
Their brake pad and stainless steel brake lines take performance to a whole new level. I can anchor down from 140+ on a 5300lb SUV running 315s all around and they are absolutely astonishing.. I still cannot wrap my head around the physics of that. I would never put giro disc on a car this heavy, as they don't have nearly the heat capacity of the RacingBrake rotors, and Racingbrakes patented cooling vein design is the best in the industry. In addition, their unique offset mounting desk allows for cold air to enter the rotors from both the front & backside of the rotor for superior cooling.
The brakes still overpower 315s on all 4s, I have never experienced braking performance like this from a steel rotor, they are literally carbon ceramic good

Do you have any basis for either one of those statements? Girodisc rotors have been in use on track cars for years and have an excellent reputation. Can you tell us more about the superior metallurgy of the RB rotor vs. Girodisc?
Thermal capacity of a brake rotor is dependent on mass, I'm sure Girodisc makes rotors that are both heavier and lighter than some RB rotors as it's all application specific. That is a blanket statement that holds absolutely no water. The vane design affects the ability of the brake rotor to dissipate heat.

My please Jose, I'm glad you're enjoying them!

I would hope when making statements like that you have experience and data on both. It's obvious, and I understand, you are in love with RB rotors but to say that Girodiscs can't do something when you clearly don't know first hand is a bit brash.
Without regrade to the most comprehensive brake coverage for Mercedes that no other competition can even come close and the fact that very few MB owners track their cars except those who just started with RB brakes, a more unbiased view of comparison would be to search some heavily track communities outside Mercedes.
1. Corvette Z06 is considered to have most track car. In this thread different brake brands are mentioned and discussed in details. Read the entire thread will disclose what brand is consider best two piece rotors. Best 2 pc light weight rotor for grand sport...
2. Nissan GT-R is considered having the toughest brake on earth, lots of brake issues due to its vehicle weight and speed. Search around two popular GT-R forums and see who is the most mentioned and favored among those serious track racers.
Most tracking customers know and agree that Racingbrake build the best rotors w/o knowing why, so for those who are interested in learning the insight, we presented an illustrated diagram in design merits to help customers understand why RB rotors are more durable and run cooler.
They are designed and constructed under 3 US patents, in addition to our metallurgy on cat iron with added alloys.
We believe the majority of users' testimonial is more convincing the test data which usually are fabricated by a company via promotional efforts for a mechanical set up like brakes.
Racingbrake has been in brake business for 30 years which should have mean something hadn't we have done something right.
Racing brake is on the forefront of braking technology... Everybody else is just playing catch up
Their new Carbon Ceramic rotors put even the best OEM CCB brakes to shame, especially their new indestructible sintered brake pads. It's a new era on CCB technology, moving forward I will be switching over to carbon as the weight savings is unbeatable.
We have been having some pretty good success racing using the RB setup (4 pot front, 2 pot rear). We got one of the overall field wins in the BMW Club Races at Road Atlanta at the beginning of Sept. and this past weekend got a B-Mod win in the Friday race on the Lightning track at the Oktoberfest races. I will make the following observations:
- the rotors are just plain awesome due to their ability to dissipate heat
- the brakes make an unusual sound due to the holes in the slots (kind of like a wind instrument effect)
- the brakes worked incredibly well for us using CarboTech or Cobalt Friction front pads and Hawk DTC60 rear pads
- we have found that when the rear pads wear below half the pad thickness, the pedal travel increases when the rear pistons have to extend that far out (although the same thing happens in the dually as well)
Track applications is where RB brakes can set itself apart from other brands, and for those MB owners who are not sure which rotor to choose, these reviews, tech presentation and the consensus from Corvette and GTR track guys might help you decide.
