NA1- NSX-R Exaust & Alloys

[markc]

In the end with the NA2R they seem to keep on ignoring the big Elephant in the room.

The car needs more power!

... and therefore bigger/better brakes.

Can't have one without the other or you'll unbalance the package.

You got that right Mark!

Being a saddo, I just pulled out my 2003 JDM NSX-R (NA2) brochure and there's no mention of any weight saving for the wheels. NSXPrime claims an approx 1.6lbs saving per front wheel and 3.3lbs per rear but doesn't give a source... http://www.nsxprime.com/wiki/Wheel_Tech
IMHO if this were true Honda would have made more of a thing about it in the brochure, especially as they look identical and therefore the construction and/or material would have to be fairly special.

My 1997 JDM NSX (NA2) brochure claims a total saving of 4kgs in total for the 4x Type S/Zero BBS's. Prime claims 1.3lbs per front and 3lbs per rear. More plausible as they're a totally differant design.

Sounds like another NSX-R urban myth... lets see one on the TDI dyno

I was with Kevin when he collected the wheels, certainly seemed light weight to me however I've not felt the weight of the normal 17's so can't 100% compare.

Hi, all.

The weight of 02R wheel together with the specially designed tyre BS 070 is just about 1.0kg lighter than the standard 17in wheel+tyre fitted to the facelift models.

Although the appeance looks the same, the 02R wheel was shaved off at several places compared to the standard one.

Thanks Kaz,

So is it the wheel/tyre combination that get quoted as weight saving or just the wheel/s?

A few lbs of metal (3lbs for a rear wheel) is a LOT of shaving from an individual wheel! I guess if they turned each wheel in a lathe and thinned down the entire inner rim that might do it?

It's great to get to the real information rather than the internet myths

I'd bet the NSX-R exhaust is the same as the regular cars (except for the tips style) i.e. quiet but not good for power.

The NSX-R NA1 which was in germany some years before for the Nordschleife lap time
was equipped with an standard looking exhaust, only the tips looked different
(2x90mm) But this car was loud.
Finally the original muffler was modified and the cats were removed.

Generally JDM NA1R exhaust is the same as NA1 exhaust, only different tips.

I have my doubt about NA2 NSX-R wheels as well, does anyone know for certain that they're really differant to regular >02 wheels... other than a differant colour?

The 02R rims
Manufacturer: BBS
Front rim weight 7.4 kg
Rear rim weight 8.4 kg

The standard 02+ rims
Manufacturer: ASAHI
Front rim weight 8.1 kg
Rear rim weight 9.1 kg

So the weight difference of the rims is 2.8 kg alone.

Excellent, deffinative information For the sake of completeness do you know how this was achieved? Differant alloy? Differant mould making a thinner structure? Both are forged construction I believe.

I wonder a) why the brochure doesn't state this? and b) why they kept the same look/style?

Thanks again

The 02 plus wheels I had said BBS forged, as far as I was concern Asahi made the cast copies as sold by macs and others in Japan. The exhaust on my NA1R had a black heatshield.

So still some room for clarification then.

Can some of the 02+ owners chip in and confirm if their wheels are made by BBS or Asahi?
