TA size Girodisc Rotors

[ViperGeorge]

Are these rotors similar/same to the ones we are discussing?

I would say no. The Racing Brake listing does not mention the TA. The TA has different rotors than other Vipers. They are the same diameter as a regular non-ACR Viper but the swept area (annulus) is larger. In other words the hat has a smaller diameter even though the total assembled rotor is the same size as a regular Viper. This allows you to use a pad with more surface area and these pads actually stick out the bottom of the Viper caliper.

Note that Racing Brakes refers to the rotors in your link as "oversize", meaning a larger diameter. A larger diameter rotor would require brackets to move the caliper further out. The TA's calipers are in the same place as a regular Viper, they were not moved as the rotor has the same physical diameter.

Most ACRs came with Carbon Ceramic Brakes with Carbon rotors. These rotors are much larger than non-ACR Vipers. The exception is if you ordered an ACR with steel brakes (which was an option) you received the TA rotors. That is what my ACR-E has.

Same 355x32mm but RB offers 3 different set up:

P/N 2218 ($898/2 rotors): RB Surface Mt design for Stoptech replacement (Pad=D968/53mm depth) - In stock.

http://www.racingbrake.com/Two-piece...r-F-p/2218.htm

P/N 2343 ($999/2 rotors): RB Center Mt design upgrading from TA Brembo surface mt (Pad=D1001/60mm depth) - In stock.
- This is the same two piece rotors that helped Igor at Momentatry Racing with podium wins -

http://www.racingbrake.com/Two-Piece...r-A-p/2343.htm

P/N 2588 ($959/2 rotors): RB Surfac Mt design for Brembo TA replacement, including the discs (Pad=D1001/60mm depth) - 4 to 6 weeks leadtime.

http://www.racingbrake.com/Two-piece...r-F-p/2588.htm

Except Stoptech OE replacement (#2218) you can run either 53 or 60mm pads with our wider annulus (65mm) discs.

Jon was with Igor at MomentaryRacing during the racing season and he should be able to provide testimonial of RB brakes.

We are proud to be a sponsor of MomentaryRacing to put our brake into real test by torturing them on tracks and compete with other race cars.

RB makes more brake options for Viper (& Hellcat) than all competitions combined.

No matter you are looking for just replacement or upgrade, standard iron or CCM we have them all.

I spoke with Mike at Girodisk today and they are ready and willing to make these for us. Just need some deposits. I highly recommend you call and talk to Mike directly about their products. Very helpfull and knowledgeable.

Great job for the community! I'm sure others will purchase them also when they need them. Thanks Eric!

Thanks Bruce! They seem like a good company with a good product! It's nice to have a more cost effective alternative for guys that are tracking their cars especially since Dodge decided to raise the prices for the stock Brembos. Mike said it was pretty crazy working with Ralph to develop/produce the iron rotors to replace the Carbon rotors that all the Gen V ACR's are switching to. He said people have reached out in the past about the TA rotors but there wasn't enough interest for a production run. Mike also said they recommend the Raybestos pads for their rotors. I'll be ordering a set as soon as we get enough interest to cover the initial deposit for them to start production.

If you are looking for an instant and affordable, swap installation BBK; something better than TA, we have a solution for you that is our 370x34mm* (vs. OE 355x32) oversize rotor kit which we use the same discs as for Camaro ZL1 and CTS-V that's equipped w/Brembo 6 pot calipers, that serious track racers there are in favor of RB two piece rotor upgrade.

Please refer to this thread for more info.

* Rotor has wider annulus (66.5mm) so you can run TA pad (60mm) or non-TA pad (53mm).

Seems like there is no reason to re invent the wheel here, or brake! Looks like RB already did a great job and have several solutions to choose from. Prices are great. Not sure why girodisc would want to do them and what would be the advantage over what is already available and proven?

I wish you guys can make a front kit that rivals Viper exchange's 380mm 6-piston setup (which fit in the Side winder IIs).
The reason I dont like theirs is it has a fat ass aluminum hat. Would be nice if it was painted black so its hard to see.

Do we know of any members here who are heavy trackers that have thoroughly stress tested the RB and can report on longevity of the rotors and pad related issues?

I agree with Bruce, I haven't found much feedback from Viper owners on Racing Brake rotors and track performance. I'm also not crazy about using caliper spacers or grinding down the metal tabs. The guys with ACR's that are switching from Carbon to Iron Girodisc are having great results and I haven't seen ANY negative feedback. Girodisc isn't re-inventing anything, they already have the measurements for the rotor, they just haven't mass produced it because of lack of interest. I'll be getting a set before my next track day in May.

[speedtactics]

They have a solution that does not require any modification and replaces the TA disc and pad. The BBK is the one that requires the spacers and modification. I don't have experience with either jut playing devils advocate here

...MomentaryRacing to put our brake into real test by torturing them on tracks and compete with other race cars...

BTW anyone here raced harder than Igor of Momentary Racing who represented Viper and competed with other muscle cars?

Our brakes are serving track racers from Porsches 911 (from 993 to the latest 991), Corvette Z06, Mustang GT350, Camaro G5 ZL1/Z28 and the latest G6 ZL1, Nissan GTR, MB C63, and 700 HP 4700 lbs monster Hellcat.

Among them we think GTR is the community where track guys put different brakes to test; for its weight, speed and popularity, you can search web or this track oriented GTR forum and find out who are there.

Putting on the RacingBrakes.com Rotors on my race car has been one of the best mods yet. now, instead of them cracking out in a half of a season, they last a full 2 seasons
it has to do with their metalurgy and casting methods. (horizontal vs vertical as most common suppliers use). this provides strength and wear consistancy that i havent seen before on any cars i race with.

I have these rotors, but haven't installed them yet. However, I did do a test fit on the driver front and concluded it is best to fully remove the caliper to do the job properly. They will be going on in May 2018, and I will give my feedback after the first or second track event.

[esm_viper]

Look forward to your feedback, thank you! I haven't bought anything yet but need to before my next track day in May.

Any interest in the Girodisc TA rotors. I'm ready to buy but they need a few more orders to start a production run.

[parabs]

If anyone doesn’t want to wait I have a set of NEW TA rotors with hats and TA calipers and pads I’d consider letting go for the right deal.

I'm not entirely convinced the Girodisc will hold up well over a long period of repeated track use. Saw a set on an ACR-E and the disc developed slight cracking, although not sure how many track miles on the set.
Was under the impression the RB (https://www.racingbrake.com/ProductD...ode=DOD-IRK-02) package did not require any modifications. The pad size "ET500 - Street (PD1001-35 & PD1383/968-35)[Included in price]" in their website is confusing. It list the D1001 size(wide annulus) and 968, which I believe is the narrow annulus pad.

You are correct our rotors are made to fit both TA pads (D1001) and non TA pads (D968 or D1383), last 2/3 digits (-35) signify compound.

RB rotors are made with alloyed metallurgy and can last for several seasons because our discs are also heat-treated before machining, so they can deliver a highly consistent brake torque under high heat w/o warping or cracking.

Ok I found the section on the website, where the rotor ring part numbers are listed. The ring part numbers are the same for both the front and rear disc.
Replacement Components:
Front Rotor Ring: D403-06-381
Rear Rotor Ring: D403-06-381

Want to bump this thread in case there are still guys interested in TA size girodisc rotors. Mike can make it happen, just need 5 guys

[sharmut]

I was tracking the TA a good amount and couldn't wait for them. Moved on to the ViperExchange BBK package. More leverage and parts are from Stoptech, easy access to replacement parts.
