I'm contemplating one of these for a general touring car and for light track use (probably no more than 3-4 HPDE's per year -- I have other cars for more aggressive track weekends). While I don't envision modding this, I have a feeling I'd like a little more turning capability than the stock setup and tires create. I've not yet seen one of the production models at the track, though I did once see (and chat up the driver) a pre-production, factory-race-prepped NSX at a track in Ohio. If I pull the trigger on one of these, it'll be within the month.

Questions:
1) It looks like there's plenty of room for wider tires without rubbing. Has anyone put a a wider, more aggressive tire (probably on a wider wheel) on this car? I'd love to hear from someone tracking the car with Hoosier R7's (but even Trofeo-R's or a BFG Rivals in something like a 265 front and 325 rear (keeping close to the same diameters) would be valuable to hear about.

2) What alignment settings are you running or have you tried for better lapping performance? (I'm not sure if there are factory performance recommendations, as the Viper ACR comes with or not...). How's the tire wear on the stock alignment, and how much better is it with some additional negative camber?

3) Did anyone who tracks this go with iron brakes to reduce consumables cost (Yes, even people who track $200K supercars find it advisable to seek spousal harmony by keeping consumables costs as low as possible!), and how do those hold up under 30-minute sessions? If you're tracking the carbon ceramics, how are those holding up, and what have you paid for pad (or rotor) replacements? Are there after market pads and/or rotors you've found, liked, and recommend?

4) Did your dealer give you any grief about warranty issues as a result of tracking the car, or are the dealers (and Acura) standing behind their product (not including reasonable warranty limitations on consumables like tires and brakes, etc)?

Thanks for any experiences you can share!
 
I think chrisn has tracked his NSX.
Another owner has installed HRE wheels with larger tires
As far as I know steel brakes aren't available yet.

Ny NSX has done about 5-6 track-day equivalents (sometimes working double duty).

I have run the stock Contis, Cup2s and Trofeo Rs, all on OEM wheels (and sizes).

Per Dealer and NSX specialist, NSX is "track ready" from factory, so no prep needed. I specifically asked about alignment settings and they ran it up to Acura engineering and said: don't change it. However, based on tire wear, it could use more negative camber all around.

No one has iron brakes yet, so no one knows anything about them.

Ceramic brakes with OEM pads work great but wear VERY fast with hard use. Pads will be expensive here. Just bought my fourth set at ~$900/set.

No reason to think tracking it will impact warranty.

Car is super capable and lots of fun on the track, but not quite as fast as my C7 Z06, which is the fastest track car I have ever driven, but I only track mostly-stock street legal cars.

We're working on a track package with pads for the ceramic brakes with longer endurance and alternative carbon ceramic rotors.
What i observed whilst tracking at Sebring with NSXPO was that pads are the main thing, you'll have about 10 pads to a set of brake discs according to Acura R&D.

Standard compound Brembo we have already listed on our site: http://as-motorsport.com/site/en/catalog-c-6/nsx-2016-c-208/brakes-c-218/
These come with a full hardware set.

Stock pads come with OE CCB kit is an in-between (street and track) compound. Serious track people usually prefer to go with aftermarket pads such as Endless or Pagid among others. RacingBrake has successfully developed a sintered pad which is a full metallic compound to deal with the extra heat that CCM rotors can produce (about 25-30% more) than traditional iron rotors.

Here are links to the in-depth & onging review on RB sintered pads.

Track Compound (Tested by a ZR1 track driver)
Newly Improved RB Sintered Pads for CCM Rotors

Street compound (Tested by a GTR spirited driver)
Prototype RacingBrake hybrid CCM/carbon pads
 
We have complete databased of all CCB brake kits set up, except Audi, Mercedes, BMW and Posrches, all others (ie. GTR, Aston Martin, Ferrari, Viper, Corvette, Camaro and more) are variants of ZR1 brake pads i.e. D1395 front and D1165 rear.

We have'nt have a chance to access NSX brake yet, but from the picture of caliper and pad they seem to fall into the same category as ZR1, which means most likely ZR1 pads can be modified for NSX if the dimensions are known.

Track Worth Wheel Package

I have had my car at Finspeed in Austin TX, and they are modeling a set of 19"x11" for the front and 19"x13" for the rear. I plan on running 295/30/19 and 345/30/19 Hoosier A7 for SSP autocross. It will rub on the felt liner up front at turning lock. Expected date of production is end of August.

Have you done anything with the suspension?
 
Just upgrade the front bar to 2019, and running 3 degrees front camber and 2.5 degrees rear.
 
Erik, those are your track settings or the car is capable of achieving those specs without modifications for SCCA Street class? Also, did you ever look into 18" wheels for the front of the car or is it non-starter?

Thanks,
Ryan

Street class allows for adjusting camber with factory available option, so you can add as much shim as you the factory bolts allow and they are very long. So no problem getting as much camber as you want. I am now at 3 degrees rear, as the car was loose at Solo Nationals and it required this addition. The 18" wheels couldn't be built by to clear the kingpin bolt.

I had Finspeed in Austin http://finspeed.com/ make 10.5"x19" front wheels that I run with 295/30/19 Hoosier A7 and 13"x19" rear that I run 345/30/19
Hoosier A7. The front rubs the felt fender liner just a bit. This is stock suspension and ride height. Hoosier decals blown off on one pic.
