Making an NC corner as flat as an S2000

Postby Curves » Mon Jan 09, 2012 2:34 pm

I am cross shopping between a new NC and a used S2000. The NC with "sport" suspension was too soft.

What suspension setup on an NC would make it corner as flat as an S2000? I am looking at a starting point so I can figure out how much factors into the cost of the NC. Of course if I end up with an NC I may go beyond the starting point :D

Fun question. The stock suspension on the S2000 is stiffer, though the chassis design is much older, heavier than NC. Thus, though NC comes with silly soft springs and sways, you can get equal 'flatness' with less serious rates on the lighter NC. The Eibach Pro Kit or Progress springs and any of our sway bar kits will get you past a stock S2000 in the corners. Give equal mods to the S2000 and the competition stays close....really close (the NC and S2000 compete head to head in SCCA STR class and the competition results have been incredibly tight). Both great roadsters and you can't go wrong with either.

Thanks Brian. Looking at those goodies in your store, the MX-5 really is cheap to upgrade compared to the Boxster I had in 2001-2005. Something that weighs heavily in favor of an NC that is for sure!

Is this flat enough for you? Vail pic is at about 35mph; 2011 Solo Nats pic below is at about 55mph. Street suspension can do almost this well and not be as "firm" as the race suspension on my car!

I considered an S2000 CR before I bought my '09 NC2 Touring. I went with the Miata in part because it was cheaper to buy, modify, repair, insure, fuel, and put tires on. Plus, I prefer my cars small.

But, as you say, the NC's shortcoming is ridiculously soft stock suspension. I'd definitely include dampers and springs and possibly sway bars in your budget. Fortunately, the NC response very well to these changes; the car is transformed with by a not-too-expensive suspension swap.

Yep. The Appearance Package (then and now) consists of a new front airdam, side sill extensions, and rear skirt. I also have the rear lip spoiler. LOVE the look, but the weight must come off.

Brian,

This has probably been asked before but, what wheels and tires are/were you running in these pics? The car looks great.

That is not my NC above. We will need to let Chris chime in on that combo in that picture, I know that he has changed a few times.

Ours uses our 38mm 18x10.5 Enkei PFO1 and I also have several sets of our 18x10 RPF1 38mm. My guess is that Chris is using the 18x9.5 45mm RPF1 in the front, and 38mm 18x10 RPF1 in the rear in these pictures.

Brian,

Sorry for the typical wheel/tire combo question...

Any suggestions on a wheel/tire combo using your Super 20 flares? I'm interested in using 17" wheels since the car will be a dual purpose mountain run/track car. So i'm guessing that a 17X10 like the Enkei RP-F1 38mm you have for sale on the site would work. I'm not interested in a staggered set up.

Thanks for the help.

Vail pic (top) was 18x9.5" ET45 Enkei RPF1s with 285/30R18 Kumho V710s all around.

2011 Nats pic was 18x10" ET38 Enkei RPF1s with 295/30R18 Hoosier A6s all around (holy fender roll/pull, Batman!).

And THANKS!!!
