TA Replacement Rotors from Racing Brakes

[sharmut]

@ ViperGeorge

How are the RB rotors working out for you?

Wanted to go with their 380mm caliper and disc package (https://www.racingbrake.com/ProductD...DOD%2DIRP%2D03), unfortunately test fit with the template on the SideWinder-2 confirms it does not clear the corner of the caliper. There's a ridge that reduces the inside clearance as you get closer to the outer front edge of the wheel. The BC-Forged RZ39 has a little more room, but too close for my taste.

Called Warren at RB today, working with him on putting together a package with 370mm(front) 355mm(rear). 6-pot RB caliper front and 4-pot RB rear. He believes it's possible to accommodate the 6-pot caliper with the 370mm disc size, but working out the details to confirm. My thinking is the 6-pot wider pad could provide a tad more torque since the pad surface area is spread over a longer area of the disc radius. Who knows if I'll notice the difference, but worth a try since I'm changing the OE caliper anyway. Backup plan is to use the 4-pot in all 4 corners (https://www.racingbrake.com/RacingBr...dod-irp-01.htm). Just putting this out there in case someone else shows interest in a similar package.

I went down the exact same decision making paths that you are going through now.... The 6 Pot or the 4 Pot RB Calipers will not fit the Sidewinders with a 370mm rotor. The 4 pot RB Calipers only leave 4-5mm clearance on the Sidewinders on 355m rotor. With 370mm you would need around extra 7-8mm of clearance.

My car should hopefully be done next week if you need more details or measurements etc...

So I just finished the One Lap of America and no complaints with the RB rotors. Brakes worked great. My driving could have used an improvement but not the brakes.

Glad to hear. Do wish I can get the 370mm with 6-pot caliper to clear the 18" wheels. The TA can use more brake torque.

What pads do you use on your car? How is the brake dust compared to stock? Does RB sell their own pads? Do you guys use different pads for tracking and street driving. The TA brake dust headache continues lol

[Racingbrake]

For street and spirited driving we have excellent low dust and no squeaking compound XT910.

For Non-TA (D968)

On my ACR I use Raybestos ST45s on the front and ST43s in the rear. These are race pads but I leave them on all the time. Relatively low dust and noise for a race pad and they are easy on rotors. They must be bedded in properly though.

Do you have to re-bed them when going to the track after a long time of street usage? (i.e., does street usage remove the bedded material from the rotor?)

I have not had to do that. Once they are bedded in they seem good until replaced. Bedding procedure is 10 hard stops from 60 to 10, then drive 20 minutes at 50 or so trying not to use brakes then 10 hard stops from 100 to 10 followed by another 20 minute drive. Smoke from brakes in normal during second stage.

Thanks for the reply.

Anyone know the stock thickness of the TA pad? I have 160 mm left all around.

Since I daily my car, I am interested in the RB street combo for my daily driving.Is this the price for a complete set?

George, those seem like a great pad for the track.

[Racingbrake]

Price is per axle set (4 pcs). The thickness is 16-16.5mm.

Do you happen to know the caliper torque specs for a 2016 ACR?
Thx!

Manual says 85 Ft/Lbs. It does not specify a difference between Viper models.

Hey man they look amazing !
Are the a direct fit for the TA ? Im having a hard time finding rotors for the TA!

[Ali_Marafie_kwt]

Which rotors and pads fit the TA package viper. I want to buy a set asap because i have a track event in November and i cant find rotors that would fit the TA brakes

[sharmut]

The TA pad shape is D1001, the Raybestos Part Number: ST43R1001.15. Uses the same pad for front and rears.
For other rotor options, you can contact the folks at GiroDisc to see if they have something.

PM if you're interested, I have slightly used set(front and rear) AP-Racing j-hooks rotors that came of my TA. Also have matching Raybestos ST47(front) and ST43(rear) pads. Used the setup for 2 track days before upgrading to the Stoptech BBK kit from ViperExchange.

Can you still recall the location of interference and amount.

A customer recently installed RB 380mm 6-pot CCB kit and might have run into the similar issue.

Most of my low clearance was at the end of the bottom end of the caliper on the OE Sidewinder wheels. It has a lot to do with wheel's barrel drop step design. For example my BC-Forged 18x11 @42mm provides more caliper clearance than the SW2 wheels.

In the image above of the OZ wheels what is the wheel offset?

[USAFPILOT]

That be looks insanely tight. One piece of debris in there and you’d get a major gouge in the wheel.

[sharmut]

Like other ACR owners using 18" front wheels with the OE CCM brakes, gouging from debris at the inner barrel is a given.
One option, the DSE item below. Have no first hand experience.

Brembo recommends 3mm clearance.
