Lightweight REAR rotor options - Page 3 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

As DAEMANO mentioned,

Racingbrake rear two piece rotor aluminum hats are designed without compromising the integrity of OE's emergency brake.

How?

We integrate a iron sleeve into our rear rotor hat to allow the use of emergency brake. Do not be confused between "Emergency" and "Parking" brake.

"Emergency" brake is for you to use it during emergency when your hydraulic brake system fails, while the "Parking" brake is for you just to park the car.

If you go with an alternate rear two piece kit, that uses an all aluminum hat.
You run the risk of damaging the hat if you apply the emergency brake while driving. Which is why they will advise not to utilize your e-brake unless your only parking your car.

Being the reason why we design or rear hats with an iron sleeve,
to safety use your emergency brake the way its supposed to be. (OE)

Weights

OE 1-pc (290x18mm) = 13.4 lbs
RB 2-pc (330x22mm) = 12.8 lbs
OE Calier = 6.6 lbs
RB Caliper = 6 lbs
Total weight saving per corner = 1.2 lbs

for our matching front
we use a 332mmx25 two-piece rotor and our 4 piston calipers weighing
10lbs less that OE's stock brakes at each corner.

It's also illegal damn near everywhere to park in this manner as well.

I've got an e-brake less car and it's about a 10-15* grade before it will roll in 1st gear.

I'm not arguing it's a good idea though. I'm speaking from experience, it's a PITA on a street car. I chock my car at home because my driveway is slightly sloped. It's annoying as hell.

I understand if RB gets 12 orders for two piece rotors, they will make them for us.
Chris, how about a group buy special pricing for two piece rotors?

:-)

Are we talking about stock size 2 piece rear rotors with the e-brake provision?

F1fletch · 05-20-2014, 05:49 PM

That is my understanding, hopefully we will receive more info from RB soon :-)

i am in for at least 2 sets of rear in stock size, personnally i don't care for the e-brake, it is for a race car that won't have it anyway.

justint5387 · 09-24-2015, 07:53 PM

Did this ever happen? What would the cost be?

SuperTom · 05-04-2018, 06:23 PM

Im guessing this never happened going to reignite the demand for a light stock size 2pc rotor. Im open to keeping or loosing the E-brake for even more weight loss. Going to be installing the lightweight Wilwood Front kit so I need something light for the rear. Car is getting close to 2450lbs so not looking for a heavy kit

I realized I went almost 2 years without my ebrake on the Vette. The handles are notorious for the teeth to break on the lever.

Did the demand for a stock size 2pc rotor ever come through. I would prefer the hat to be completely aluminum as I only ever use my ebrake for parking.

If the ultra rare situation occurred where I would have to use ebrake an emergency occurred then I wouldn't be upset to ruin a rotor if my life was saved
