TA size Girodisc Rotors

[esm_viper]

Is there any interest in having Girodisc make their rotors in the same size as the TA rotors but priced the same as their narrow annulus rotors on their website, $950 a pair rotor and hat? I spoke with Mike Owen and they'd be willing to produce these rotors for us if there is at least 5 people that commit to buying. I think it'd be a great cost effective option for us non-ACR guys with stock rims. Let me know if anyone is interested and I'll start a list.

Is that cost rotor plus hat or just rotor and then reuse our hats? If just the rotors is that really much cheaper than getting Brembo replacement rotors?

The Girodisc's are $950 a pair hat and rotor. Around $2,000 for 4. I've been emailing Jon B and the Brembo TA rotors are around $1,000 EACH. Around $4,000 for 4.

[ViperGeorge]

If they are the same thickness, diameter, and otherwise the same as the OEM TA rotors, I'd be in for a set. My ACR-E has steel TA brakes.

$1k sounds like it includes the hat unless the price for just the rotor has gone way up. I would have swore he had a post early last year where a pair of rotors only (no hats) was about a grand.

If the current price is $1000 and the price a year ago was $1000 how has the price gone way up? Am I missing something?

[esm_viper]

That's ridiculous if they doubled in price! I'll try and get clarification. This is copied from an email from Jon. MSRP on TA rotors is $1265 Each! 25% off = $949 each by credit card. Pay with check, or B of A or USBank direct walk-in deposit = 27% off.

Here's an old link to a Jon B post from 2015.

Jon just said this is the CURRENT pricing and that Fiat raises their prices monthly. MSRP on TA rotors is $1265 Each! 25% off = $949 each by credit card. Pay with check, or B of A or USBank direct walk-in deposit = 27% off.

So, the Girodisc rotors are $950 a pair including hats. Half the price of the Mopar/Brembo versions. Correct???

[esm_viper]

I believe so if we can get at least 5 people to commit!

ViperGeorge - You are in a different boat with your ACR, according to Mike at Girodisc, the iron rotors they are selling to the ACR guys are the same size as the carbon rotors.

His came with TA rotors, not converted carbon rotors.

[esm_viper]

I knew that. But now that I think about it, I forgot that he also has the 4 piston calipers. My mistake.

Info from Girodisc.

1. *Yes $950 is for a pair of the complete assembles ready to bolt onto the car.
2.* Yes they are 355mm x 32mm with the larger annulus just like the OEM rotors.
3.* There are two different variants of the wide annulus rotors, the early ones which are curved vane and have similar hardware to ours, there is an outside chance that our rings will work on those hats but if I recall I believe the PCD is a little off.* The later wide annulus rotors which are pillar vane and have the H-bobbin hardware will definitely not work with our rotors.
4.* The cost of the replacement rings is $600 for the pair and that price includes all new hardware as well

[esm_viper]

I think this is a no brainer.... let's start a list and get these made!

No, my ACR is an ACR/TA it came equipped from the factory with TA brakes. It has the same brakes as a TA, it did not come with Carbon Ceramic Brakes. If the rotors are the same as a TA's then I'm in.

Please explain Girodisc's number 3 comment. Will their rotors (hat and all) work on a 2017 TA brake setup?

[kriskyk]

Are these TA rotors at a more economical price point or something more?

I'm delineating over brake upgrade options for track days.

@ esm_viper
Can you check with GiroDisc if the VANE count is the same as the OE Brembo? If the ring material hardness is comparable to the OE TA Brembo, they could hold up as well. Do know someone with a RS4 with GiroDisc, did not hold up as well as he hoped with track use and the weight of that car.

While looking around for alternatives and found a site listing Brembo type-3 replacement rings (BRE-906530 BREMBO BRAKE ROTOR 355MM X 32MM) for ~$474 each, have not had time to research fitment to TA OE hats.

Currently trying out a set of AP-Racings J-hook rotors (narrow annulus) with ST47 and ST43 pads. They have a higher vane count and lighter. Only had them out for 2 track sessions, too early to say how well they will hold up.

The #3 comment was in response to my question... 3.* Will the Girodisc rotor bolt to the Brembo hat?

Yes they are.

TA rotors have a larger annulus (larger swept area) and are heavier than standard Viper rotors. Despite what some people may think this does not improve brake torque but it does improve cooling. You could use them on a standard Viper as the TA uses the same calipers as a non-TA. Pads are different though. The pads for a TA have more swept area to them, they stick out the bottom of the caliper where stock Viper pads do not.

TA brakes are less likely to fad than stock Viper brakes. as there is more area and mass to dissipate heat.

I went with TA brakes on my ACR-E as the replacement cost of the Carbon Ceramic brakes on an ACR are super high. When you track it a lot this adds up.

This is very helpful

Have you ever felt that the TA brakes left much more to be desired?

Trying to decide if I just go the TA route or just buy a big brake kit

With the right pads (I use Raybestos ST45s in the front and ST43s in the rear) the car stops like you threw out anchor. On my ACR-E I do not notice the dreaded rear end wiggle under heavy braking either. On my 15 TA 2.0 the rear end wiggled a lot until I changed the rear calipers for the reduced bias Racing Brake setup. As I understand it the ACRs have a different brake bias than the TAs.

[esm_viper]

Here's all we need to do to start production, I've added a list of interested people and if you wouldn't mind updating us if you called and put down a deposit. They are closed today but I plan on calling them Monday to put down my deposit.

A 50% deposit from 5 people would do the trick, so $2375. People can call 360-306-3263 in with their CC info or I can send PayPal invoice to everyone whichever is easiest for you guys.

I run ST47 front and ST43 on the rear on my TA and the rear wiggle hasn’t happened since I changed to this pad combination and you better have your belts tight or you will be eating the steering wheel.

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