multi plate or single for clutch???

[RP-Motorsports]

I will be buying another NSX in 05, and I want to use this purchase as a dedicated track car. I have already bought some parts, and will also be buying an accusump as well.

My question is this; What holds up better on the track, a earlier multi plate clutch, or the later years single plate clutch. This may factor into the year I purchase. I am leaning towards at least a 94 for the passenger side air bag for instructors/students, obviouslly I would like the 3.2, and the 6 speed, but I feel the non-targa and the clutch mean more to me than the 3.2/6spd.

Trackcar owners please help me!!!!

Thanks in advance

I think the cost differences mean the most to me. The twin plate is cheaper. Even if the single lasts a little longer (debatable), the extra few hundred dollars is not going to be made up. Before last year, if you wanted the six speed, you had the single plate clutch. Now that Honda has the new NSX-R, there are parts that will convert a six speed to use the dual plate clutch.

My other thought is that you have many more choices in the twin plate setup, both in clutches and flywheels. Lastly, the twin plate "should" have less inertia and lighter weight, giving you a "little" bit more rwhp.

As far as getting the '94 for a track only car, do not waste the money. Find a '92 with a snap ring, get it really cheap, and use the money to build your transmission the way you want it, with the clutch you want. I am not sure that the airbag would be that beneficial at the track, without head on collisions. JMHO.

I never thought of getting a snap-ring car! I could get it for a few grand less, and put in all of the parts new at that time. Makes sense. As far as the airbag goes, I drive 50% of the tracktime @ Road America which is one of the highest top speed tracks in North America and has a lot of concrete, trees etc. It was just a bonus safety idea. Thanks for the info.

Just FYI, the passanger side airbag was introduced in 1993, so it would be safe to look for a 1993 or 1994 if you want a coupe with dual airbags. Ofcourse, you could shell out some big bucks and find a rare NA2 coupe or even a Zanardi also.

What sense make the two airbags on a track car with 4 or 6 point harness and (maybe) a roll cage? I don't know any race car with airbags. Need a serious answer from an expert because I removed both airbags from my '98 track only cp. Do I miss any benefit in case of a crash?

Totally agree. If you are seriously making a track car, you should go the extra effort and installing Comptech rollcage + harnesses + bar padding.
I currently run my street/track NSX with just Dali harness bar and Recaro SPGs and without airbag. I feel plenty safe that way when I have my helmet on, but like you say, your track is fast and has trees... I dont' think a NSX airbag will make a difference for a T-bone accient at 80+ mph.

Airbag, coupled with helmet is really not a good idea. There is an incident in Laguna with one of the BMWCCA school, that the airbag deploys and hit the helmet. Breaking the visor and push the visors to the opening and injuring the instructor. The fact that he is also wearing a glasses didn't help. the bag pushed the glasses and injuring the eye.

So for track driving, I would not want a car with an airbag.

I too heard about the incident at Laguna Seca.

But why would someone have the visor down while driving a coverd car?

I would have said to keep dust from bothering contacts, but he is said to have been wearing glasses. Probably just thought it looked cool.
