early NSX understeer??

MetalSpikeRacing · 7 June 2009

Hey guys,

I dont know if it is only me,
But do early NSX's with not power-steering do understeer a little?
Or I am just spoiled from my last car?

I have not got the car to the track yet since I am waiting for suspension, but on some spirit driving, I can feel the nose pulling away from the apex instead of diving in.
Maybe it just needs an alignment? the car is pretty muck stock with ugly big wheels on it.

Coment?

Thanks,

What tire size/compound front and rear?

How long have you owned the car?

What was your previous car?

KooLaid · 7 June 2009

Yep, just a hair. Try different tire pressures. Then different tires. Then adjustable swaybars. KISS or you'll end up where I was with thousands and thousands spent and handling nowhere near where I wanted it to be.

Just what I though.

Tire compound crap.

How long I owned it? A couple weeks.

What did I track before? Muellerized AWD DSM, Me and Mueller managed to get it to make it a "neutral steer car" I loved it. But thats another story and in the pass.

I am not complining, Just make sure that waht I felt while shake the car down was correct.

The car will a track and shouldnt be a problem to fix it, It wont be at FX level but I am hoping to make it fast enough.

Thanks again,

Go look at what tire is on the car, size and model. You can easily change the handling with tire pressures and alignment.

Tires are Nangkang, 215/35/18.
I remember in my newbe days, those tires almost cost me a car when on an on-ramp they friking let go way under the treshold an avarage decent tire would of.

Those are the tires that came with this NSX.
I probably will be looking for some a032r's or at least RT-615's to begin with, thinking on 225/35/18 front and 285/35/18 at the back with the right off-set,
I wouldnt mind having to rolled the fender if necesary.

You run 215/35/18 all around?

How wide are the tires AND wheels front and rear?

wow, A032?? it's already the age of A050...
you don't want understeer: throw your 18 inches front tire away, the 35 tires have too little side wall.....and those tires are not really anything you want to take to the track, especially on nsx.

nsx generally don't understeer, but with the slow steering ratio, it felt it's going to.. but then yes, alignment and tires play a big role too.

i like the 215 front, 240 rear combo. 02+ OEM is 215, 255, 91-93 is 205/225
my track setup is 235 / 275

have fun.

KooLaid · 8 June 2009

I read somewhere that having a LARGE stagger difference between front and rear gives the vehicle a tendency to want to go straight. I'm thinking a 225/265

Last time I checked, nankang anything is crap for anything that gets driven hard.

Front : 215/35/18

Back: 265/30/19

But they dont matter, I wont be keeping them.
Would you??

I guess, I will to learn RWD dynamics and set up now, completly diferent to AWD.

stuntman · 8 June 2009

Common track setup:

17x8 with a 235/40-17
18x9.5 with a 265/35-18

Yokohama Advan AD08 would be a good street/track tire choice.

R-compounds:
Yokohama A048 (A050 coming out soon)
Nitto NT01
Toyo R888

oh, and some KW suspension

asylum · 8 June 2009

I would take the Nankang out. They are ok tires for an Oldsmobile but I would not keep that on a NSX.
Anyway, you will have to tail brake and transfer weight to the front in order to take all the advantage of the insisivity of the NSX.

Start with some performance tires as Stuntman and others have mentioned.If you need help after that ,come on back.BTW I know what a mullarian duct is http://en.wikipedia.org/wiki/Müllerian_duct but what the heck is a muellarized dsm

John Mueller, a tuner in CA, that uses JIC coilovers. Works on the ugly cars, like Evos, STIs and the Talon/Laser/Eclipse triplets. DSM refers to Diamond Star Motors. The mistake of trying to marry Mitsubishi and Chrysler which worked about as well as Chrysler and MB. They say the third time is the charm, but Fiat is going to make an ugly bride.

The NSX equivalent would be a "Comptechized" if you were gay enough to make a noun into a verb.

MetalSpikeRacing · 8 June 2009

Wow!!!
That was uncall for.
Way to bash a very profesional shop and a personal friend, it is ok if you dont like those cars, because you own an NSX but wow.

Anyways, for the rest of you guys with actual techichal input, thank you very much for your help I really aprecciate it.

I will take the car to the track on the weekend with the stock suspension and see how it does and what it needs.

I didn't say anything about the quality of his work. In fact, I have heard that he does a good job on suspension setup.

As far as DSMs, STIs and Evos being ugly. Just like a momma I guess you would have to have one to think they're beautiful.

Although, I still stand by comment that using the term "Mullerized" is kind of gay. :tongue:

The Captain means no harm. Good guy all in all.

A grain of salt or slightly thicker skin would help.

+1 on ditching the Nankangs. How did they end up on an NSX ?

If you are going to track the car frequently adjustable sway bars are a must.

Ooooh I was wonder what Muellerized meant also. I looked it up on line and it still didn't make any sense. Thanks for clearing that up. Yeah, Muellerized is pretty gay sounding. At first, "mullet" popped in my head and I still couldn't make the connection lol.

No, this is Mulletized....

Nope, this is ,

I dont know how the tires or wheels end up on the car, that is how I came when I picked it up last week.

Yes the car would be a track car eventually, In a couple weeks I would start piling material and parts to built the turbo set up that will go on it, that is another story.

I just want to put some good wheels and the JIC's on it asap, it seriusly looks like crap.

It would be some work to make this car faster, reliable and still handle like a champ, but nothing that we can figure out.

In Brian's defense, the tires were on the wheels when he got them and we discussed the Nankangs. He felt it was better to just let the buyer end up getting whatever they wanted instead of putting Falken 615s or something else decent on them. No sense in putting four new tires on a car that had four new tires (even crappy ones) when you didn't know the buyers ultimate goals/preferences.

Its very hard to get any money for a DSM even when it has built to the teeth.

I have been reading on the KV variant 3 coilovers, But It seems like their club sport would be a better choice, will see.
