TA Replacement Rotors from Racing Brakes

[ViperGeorge]

My ACR/TA has TA steel brakes but it was time to replace the rotors. I looked around and settled on the front and rear rotors from Racing Brakes. Wow, are they beautiful, true works of art. They are also cheaper than the OEM ones. Just changed them today and the swap was easy (well except for having to remove and reinstall the parking brake caliper - that's a pain).

The RB rotors come with a black hat and black finish on the rotor surface. I don't think the black on the rotor will last but boy does it look cool when new. The rotor hats mount to the disk with a center mount design not to the surface like the OEM ones. This should help with cooling as there are openings in the center. They also have holes cast into the slots on the disk. This should also help with gas venting.

Now all I have to do is find a lonely road where I can bed my race pads in.

Here's info about the rotors:

and here's the specific kit I ordered:

By the way, here are a couple of pictures.

Youre the first with that tire/brake combo. keep the reviews coming!

The tires are PS2s in the front in 295/30/18 and PSSs in the rear in 345/30/19. I'm using SWII wheels. Tires and wheels seem to work well. The tire and brake combo will work on any ACR with steel brakes, any TA (1 or 2), and any other Viper. If you run them on a regular Viper the wider anulus lets you run TA pads.

looks awesome!

Their website list 2 brake pads (D1001-35 & PD1383/968-35) are the front and rear pads the same size, meaning both front and rears are the TA versions (wide annulus)?

Both front and rear are wide annulus.

Why does ''wide annulus'' sounds weird when I read it ???

Well at least it isn't wide anus.

Thanks. Tried the AP-Racing j-hook rotors with Raybestos ST47/43 (R780), uses a narrow annulus and did not feel as firm and initial bite as the D1001 pad size.
Still waiting for Essex-parts to come out with a their 370mm Radical package.

Technically speaking a wider annulus does nothing for brake torque. There are only a few ways to increase brake torque. One, better pads (Raybestos pads are as good as it gets), two, bigger diameter rotor to provide more brake leverage, three, increase of brake line pressure to the caliper. The wider annulus only helps with cooling and thermal transfer. Of course any change you make to one axle must be balanced with the other or the ABS will not behave correctly.

StopTech used to have an excellent write-up on this on their website. It may still be there, I haven't checked in a while.

Agree and was my original thinking in making the AP-Racing purchase. It was going to reduce the consumable cost and shed some weight. I'm not saying it does or does not stop/slow the vehicle any better or worst, it's the pedal feel that changed. The D1001 feels more firm or perhaps the better description is more substantial.

Do you know the weight reduction from these rotors vs the OEM TA rotors ?

The RB rotors are about 4 pounds lighter than the OEM 1 piece. They are however 2.5 pounds heavier than the OEM 2 piece rotors.

Damn , George , those are just too pretty and color coordinated , just don't drive your ACR/TA, please, ha?!

Yea that's not going to happen. Already have over 10,000 miles on her. By the end of May it will be almost 14,000. i really should have bought two of them. One to drive and one to preserve.

The rotors do look cool in black but unfortunately the black on the disk wore off once the brakes were bedded in.

[SilveRT8]

So, this would put them about equal weight with the heavier OEM TA rotors.
That is if you meant that the OEM 1 piece are from the base SRT, and OEM 2 piece being the Track pack- GTS Stoptech ?

Hi George,

Yes, after a few hard stops breaking the black paint area where in with pad will disappear, while the rest of area remain protected from corrosion - A very good and effective rotor surface coating first implemented by RB.

How you like those rotors so far, can you post some pictures after the rotors are broken in.

Thanks for sharing.

I was quoting the weights from the Racing Brakes website. I believe they are comparing to the Stoptech 2 piece rotors not the TA's. So my guess is they are about the same weight as the TA's OEM rotors but Warren from Racing Brakes should chime in.

Bedded the brakes in the other day with my Raybestos pads and they stop great. Yes, the black wore off the disk. I'll post up some pictures when I get the chance.

Correct. Wt comparison is based on "Non TA" Stoptech 2pc rotors (which is made to fit with earlier models of 53mm pads), since we don't have the weight data on TA rotors so they were not listed but you can see below link, we also offer TA replacement with surface mount design which weighs @19 lbs.

Apologies SilveRT8, didn't see your post was directed to me. Did not weight the J-hooks against the OE Brembo. The Brembos's had considerably more track miles at ~31mm thick and didn't make sense to compare the weights. The j-hooks rotors are sitting as back-up for now and could weight them if you are really interested in knowing.

Do wish Essex-parts would get their 370x32(front) and 355x32(rear) Radical package done. Their radical calipers are lower profile than the OE Brembo to help offset the increase in disc diameter. My desire is to maintain the 18" wheels up front and want the most clearance possible to reduce the chance of objects wedging between the caliper and inside barrel, eventually weakening the wheel.

[Racingbrake]

RB has a rotor kit 370x34mm (vs. OE 355x32mm) fits under OE 4 pot calipers and 18" SW wheels.
https://www.racingbrake.com/Two-piec...e-V-p/2504.htm

The disc are the same as Camaro G5 ZL1 & CTS-V G2.

In stock.

Kit includes everything you need for an instant BBK:

• 2 ea. Oversized (370mm) RB center mount two-piece rotors fully assembled ready for installation (see installation note re widening the rotor clearance)
• 2 ea. Caliper spacer to space OE caliper up for the larger rotors
• 4 ea. Longer M12 Gd 12.9 alloy steel caliper mounting bolts

Features & benefits:

• Cost only fraction less than 1/3 of a 6-pot caliper kit.
• Not only rotor is larger, the rotor ring has wider annuls (65mm) for extra thermal capacity to prevent overheat and brake fade.
• Can upgrade to larger ACR-X larger pad (D1001) for more friction area than OE (D968) and Stoptech 6-pot caliper..
• This kit allows you to use larger pad (same as ACR-X) which is a very common and popular one in motorsports communities, lots of supplier and compound to choose from and can help you lower pad replacement cost over the time.

Anybody tried the 370 mm rotor upgrade?
https://driveviper.com/forums/thread...ighlight=370mm

[Racingbrake]

Flexibility is how we design and built on those kits.

You can progressively oversize your OE's 355x32mm rotor to 370x34mm HD track rotor same as we offered for CTS-V and Camaro ZL1 (G5) while maintaining the same OE calipers, use either Non TA or TA pads, fit under 18" SW wheels, and better yet you can re-use the same rotor hats* as OE size.

The 370x34mm rotor kit comes with needed caliper spacers for a 100% bolt on installation, just need to dremel the metal plate a bit to fit the thicker rotor.

An instant BBK w/o the associated cost impact while retain stock set up - What can you ask for more?

*Thanks to RB's patented center-mount design, unlike traditional surface-mount, changing the rotor thickness will not affect the offset.
