Anyone have weights for each of the options?

Ok, it's a heavy car. Let's say you want to come up with the obsessive-compulsive lightest possible spec...

Honda press release claims the carbon brakes save weight over iron rotors. Ok, but how much?

Ditto carbon roof? Carbon interior package?

Weight of the manual vs automatic seats?

Any extra weight associated with the tech package (sensors in the bumper, more speakers and amps, etc?)

Which wheels are the lightest?
 
I believe the Y spoke is the lightest wheel

Haven't seen anything on weights for std vs. CF

The rear wind spoiler just adds weight

The CF roof should save a few ounces vs aluminum

This is a luxury oriented car. I want my upgraded hifi, park sensors, nav, and electric seats thank you very much

I saved weight by avoiding the satellite antenna
 
other than the ccb, i think the seats are the only thing that might save some weight, so a $167k car is the lightest (manual seats, ccb)

CF is for looks.

I definitely prefer manual seats over useless automatic seats that doesn't move up and down. The CCB should be single biggest weight saving option. I hope the carbon fiber roof reduce more than just a few ounces, otherwise $6k is just for looks.

Remember my unofficial NSX weight reduction thread? Odd thing about this car vs Gen 1 nsx is that, despite its weight, it feels lighter, corner like McLaren with similar sensation. GTR on the other hand is different, you feel the weight. It must be due to lower center gravity, torque vectoring.

I am waiting for high flow cat and exhaust, both should reduce weight and increase power noticeably.

I literally just reread your entire weight reduction thread a few weeks ago in the Gen 1 section. Still a great reference point!
 
Wow. What a ripoff if so.
 
I wonder about the roof too. I was told by an engineer that it was a real carbon roof, but I recall reading one of the threads where someone saw during the manufacturing process that it was just an overlay.

So my logic sort of leans towards it being an overlay, unfortunately. If it was a true structural carbon roof that would reduce the center of gravity even more compared to an aluminum roof. And that would follow in the theme of the car, but I would've imagined that Acura would have went with that standard. Also, the manufacturing process to integrate a real carbon roof into the structure along with the high strength steel A-pillars I feel would be complicated and different enough from a regular aluminum roof to be a big hitch in the process, and not just an easy add on option.

That's just my opinion, but it would be nice to be proven wrong though :rolleyes:.
 
After reading the post about doubt that the roof was real CF, I asked the NSX Specialist, who confirmed it is a real CF roof.

If I paid $6K (which I didn't) for that option and learned it was a disco job, I would be ripping mad.
 
An ultra-high-performance carbon ceramic brake rotor package (15.0-inch rotors up front/14.0-inch rear), available as a factory option, offers a substantial reduction in weight, saving nearly 52 pounds (23.5 kg) over the standard brake package along with improved fade performance in high stress conditions, such as track sessions.
 
As said above, carbon ceramics offer the greatest weight save. Likely followed by carbon roof, manual seats, and not ticking the audio box. Other carbon components and alcantara are also weight loss, but mere ounces here and there. Spoiler is tacked on, so a weight-add even though probably not much.

Carbon fiber is very light, will make other traditionally lightweight components feel heavy, such as aluminum, magnesium, or even plastic. Of course if there's a carbon overlay that's a weight-add, however I can't imagine Acura would do an overlay on the roof, especially considering cheaper cars feature actual carbon roofs e.g. M3. Alcantara will be substantially lighter than leather and slightly lighter than most cloth but that's not a lot of weight to begin with, perhaps a couple pounds vs leather over an entire interior. But the fact that Honda doesn't go out of their way to advertise weight savings means most of these carbon and alcantara options don't add up to much.

To get a good idea of how little things can add up, lookup McLaren's press release on the 675LT which talks about savings down to ounces for various items. Porsche also often discusses weight savings of particular options in a lot of their literature.

No matter how you cut it, these cars are all going to be pretty heavy. A no-spoiler, carbon everything, alcantara everything, manual seat, base audio car might come in at 100lbs less than the heaviest spec. Definitely noticeable but not earth shattering. Hopefully the Type R will bring a few hundred pounds of savings whenever it hits, likely through a much more spartan interior, lightweight bucket seats, more structural carbon, lighter wheels, etc., perhaps even going without the hybrid system.
