Any chance you can weigh the complete stock rear system with the drum hardware? A few of us are curious about the weight savings possible from the rear brake setup.

Poor wording on my part. The "hub spacers" don't actually change any geometry. The factory dust shield & e-brake assembly are the exact same thickness. All the spacer does is replace the thickness lost by removing the dust shield and e-brake.

If you look back at the first picture the top right picture shows that assembly and the bottom left shows it being replaced by the simple aluminum spacer instead.

If that spacer wasn't there you would have to have shorter axles and the wheel offsets would change. I edited the first post to avoid confusion.

Question on the e-brake delete. This is a really interesting project with no useful resale value except for owners who never drive their cars on the street. Are you planning on selling the rear wheel kits for track only use or is it just an exercise to see what happens on your own car?

Interested as well. My FRS will always be a DD, with focus slowly going toward the track after it gets paid off. Gonna need an e-brake but I LOVE this setup

what's the capability of the 28mm kits vs the 32 mm ones when it comes to FI and track days.

To be honest the number one reason we are doing this is for our own car. We realize we will never make up the time invested in sales but we do hope to sell a few. Street cars can always use a hydraulic e-brake.



We could offer a bolt in hydraulic e-brake as an option if need be. Personally I plan on driving my car on the street with no e-brake but I live in a very flat area.



The 32mm is just way overkill, we actually chose to use the 22mm rotors. The only reason the standard StopTech kit comes with such big rear brakes is to clear the e-brake. The smaller rotor and caliper really help with bias as well. Anyone who removes their ABS will notice the rears locking way before the front with stock or the standard StopTech kit, we are hoping to improve this as much as possible.

Even the 22mm will hold up for a full season for most once a month track guys. I had these exact same brakes on my 600whp S2000 Time Attack car and the rotors lasted the whole season, they are still in great shape. Of course we will be personally testing these on our FR-S before releasing them but I expect similar results.

To us it is well worth the time invested even if we never sell one kit, there is nothing more important than removing unsprung & rotational weight from a race car, and to be able to remove both and gain braking performance is a no-brainer.

I don't know about NC, but most states require an emergency brake by law that has an independent actuation system. They define stopping distance from a particular speed.

Edit: Found this. From G.S. 20-124: Every motor vehicle when operated on a highway shall be equipped with brakes adequate to control the movement of and to stop and hold such vehicle, and shall have all originally equipped brakes in good working order, including two separate means of applying the brakes. If these two separate means of applying the brakes are connected in any way, they shall be so constructed that failure of any one part of the operating mechanism shall not leave the motor vehicle without brakes.

@Carolina Dyno
Just out of curiosity, did you look at moving the rear brakes inboard to reduce some unsprung weight? Is there anything that would fit?

Brembo makes separate cable actuated parking brake calipers, I've never looked to see if stoptech does. If this kit had that option I would be all over it.
