Very interested in how this works out
We potentially could save nearly 50-60lbs of unsprung weight

And the handbrake caliper, like this in red:

Pic about some software used for the custom procces of the handbrake caliper:

Yes, around 45lbs per axle, but im scared for pass the legal test, NSX dont designed for 50-50 brake bias, not even today rear engine Porsches (i use same kit front and rear), i drop center gravity, some extra size in rear tires but not enought, i will need softer treadwear rear tires for avoid block front tires first, too scared for the little handbrake caliper from Hispec, they are for kit-cars, and the most powerfull is for max weight 2200lb cars, and i need pass the handbrake legal test too.

How wide are the CCM disks you want to use?
For the handbrake you can use the Brembo calipers like I do
Im adapting small carbon ceramic brakes (around stock size), a lot custom work, hats, handbrake calipers and specially with caliper brackets for his small diameter (small space for brackets), they are almost finished but dont test yet, i will post pics in the future if all work fine.
They are called "freno carbon" if you want look pics, i dont post links because is my first post in the forum and pics come from commercials, probably dont allowed.
Price and weight saves are very nice, rotors weight around 4lbs and calipers around 3,7lbs.
Another option i checked before with good price and big saves was about "Devil brakes", they are titanium with ceramic coat, but probably is better option specific brakes for NSX like Racingbrake offer.
Sorry for my bad english, write from Spain.

I live in the other side (Valencia), yet we are "iberians", but my family is very close of Portugal (Extremadura).Hi neighbor :wink:
Are you working with Freno on this, or you bought their kit and doing the custom work by yourself?
This kit looks to be developed for specific lotus cars... but those models are lighter and less powerfull than our NSX... this means the rotors, calipers and pads will be submited to a lot more heat and stress... Have you asked Freno if the kit will withstand this increase in temperature?
- I would not mind to pay a bit more for something completely engineered towards our NSX, especially such a lightweight Carbon setup that could be used on the street and that could offer the right bias and an e-brake solution... But i guess this is still a dream...
Please keep us updated on your setup and don't forget to share information, pictures and a review on how this kit behaves!

We've started working with Freno recently as well. Hopefully we can bring this to Prime in the near future. FWIW, testing/tracking comments from the local Lotus club(2000lb+, 400hp) was encouraging for us as the carbon disc shed heat way quicker than the cast iron so it just might be ideal for us being heavier. We were putting around this car to ck the cold temp behavior and its fine with no noise at all.
The only way to find out is to make a set and try it. At least so far the math works out fine on paper. FYI, the Lotus upright/knuckles , are cast iron and the wishbones are fab'ed steel, same with the 4C.
Bruno, I "think" we are stuck with the caliper/piston sizes as they were made for the F2 cars in 2012. we(Prime) doesn't have the economy of scale to ask for a new caliper. We'lll ask and confirm.

It's not only a question of temperature but also of thermal shock and of course total energy dissipated.
...
Please ask and confirm! maybe if they offered replacement rotors and pads for a popular setup like stoptech we (Prime) could get the best of both worlds... weight savings and nice bias...
^^ This is my exact concern! Carbon rotor may withstand the very hight temperatures that will be generated and thermal shock... but what about calipers? and and rotor hats? and bolts? and pistons? and seals? and brake fluid?... and...? and...?
Only testing will tell... but i would feel a lot more confident if rotors were bigger and thicker than OEM... like 330 x 32 or 34... and i bet that even with bigger and thicker rotors, weight savings would be great!

I agree with the following...Has anyone done any weight reduction that they wished they had not done for the car? I'm about to go carbon front and rear beams, abs delete within 10 days. I removed my doa stereo the other day since I had to remove CCU and send to briank for repair. Wiper arms and motors went about a week ago and now I have to manually wipe down the windshield in the morning so maybe that wasnt a good idea to remove. (better go buy a squeegee today). Momo tuner and nrg hub were installed this week. I'm thinking about removing the TCS (light always on since I have an aem ems) & SRS modules. based on the spreadsheet and I have a ctsc I should be @ 2829 lbs right now and with my planned mods should be at 2710lbs. This includes firewall sound deadening removal and I was thinking about just ripping out the thick backing on the carpets vs buying new. I havent been on prime for 11 years (busy) but have been on previously since 2000 and have owned my car 17+ years. The car has basically sat for 11 years other than the occasional start and I started driving it about 2 months ago to decide if I may want to sell it or something else to make room for something different. I'm not selling it, resale value isnt important to me either since I will be dead when the next owner has it but nice to see values are up on these anyway. I took it into autowave a few weeks ago and they were surprised since no service since 2006 and maybe a few hundred miles driven since they did my ctsc install (389 rwhp back then). They installed the taitec replica exhaust for me to replace the rm dtm I have had on. Love the car again and I mainly decided to drive it again since the mclaren view was similar when I was deciding to buy (but not superior) but reliability issues made me rethink buying but love the doors. I drive it more the last 2 months than my '11 basalt blk boxster spyder with 6sp and buckets, or my arancio borealis egear gallardo spyder. Also much better for fun driving than my '12 pdk 997.2 turbo cab was
I agree with the following...
Remove - TCS, stereo, Steering wheel, front/rear bumper beams, factory exhaust
Don't agree removing - sound deadening, wipers, SRS module (unless replace with new 2000+ unit which is much lighter and better)
Suggest - Recaro (or similar) bucket seats, 02+ headlight conversion, remove spare tire assembly, headers (if you have stock 91-96)
