That's not a wheel. THAT'S a wheel.

When I bought Emma, my 1995 Miata, she came with numerous performance parts. Since my plan was---and is---to make her my dedicated track/autocross/time-trial* car, this collection of parts was the primary reason I bought this particular '94-'95 Mx-5**.

One of these parts was a very nice Momo Team steering wheel. Unfortunately, at 300 mm in diameter, this wheel is laughably small. When Alison drove the car, she said she felt like she was driving a Cozy Coupe, but with enormously higher steering effort.*** the previous owner was a taller guy, and I think he needed the extra clearance for his knees and thighs, especially when sliding into the race buckets. Aside from the required steering force and the sheer silliness, there was another drawback to this size wheel. I was unable to see my oil-pressure gauge (sic) or the tops of my tachometer and speedometer. Observe:


I needed a new wheel, clearly. But what size? After poking around on SpecMiata.com, Miata.net, and the Chesapeake Area Roadsters forum, I settled on 350 mm and ordered a Momo Mod 78 in that size from an online retailer for a price well below MSRP. As you can see, gauge visibility was dramatically improved:



Steering effort was reduced, as well. It's now a little heavy at anything under about 5 mph, but at any faster speed, it's just about perfect. As a result, the car feels much lighter and more nimble, even though the vehicle itself is unchanged. This wheel comes with a suede cover, which I thought would give me extra grip. I was correct about that, but suede has another benefit: it just feels very nice.

The Mod 78 has an "anatomic" grip, which appears to mean that the rim is deeper than it is wide. It's fine when my hands are at 9 and 3 o'clock, which is where they spend 90% of their time, but at other positions, it's simply uncomfortable. If I had to make the purchase over again, I might go with the Mod 69, which is the non-anatomic version of the wheel.

Here's one more photo for you. It's a pic of the stock wheel (about 370 mm), the new Momo Mod 78, and the old Momo Team. The difference in diameter is readily apparent, but what you can't see is the weight difference. The two aftermarket parts have similar mass (about 7.5 pounds), but the stock wheel is probably around 15 pounds, due mostly to the airbag.


* Someday.
** I was looking specifically for a 1994 or 1995 Miata, for reasons I'll explain later.
*** Emma was built with power steering, but the steering rack has been depowered. This modification results in much more precise steering feel, but at the cost of higher required force, especially since the power rack has a quicker ratio than the manual rack that was available on the NA Miatas.

Girlin' it Up in the Garage

Tonight, I performed some maintenance---manly, according to conventional gender roles---on my track car---double manly---while wearing Alison's slippers---girlie. I can't decide if my transvestite auto maintenance* should count as masculine, feminine, or simply strange.

* The floor in our garage has been quite cold lately, so I needed footwear. Alison's slippers** were conveniently placed, and I only planned to be out there for a few minutes.

** These are the slippers that Newton seems think combine all that's good about socks with all that's good about leather. Mmm.

Welcome, Emma

As most of you know or can guess, I bought a car---another Miata---during our trip to Atlanta for Dragon*Con. (I'll post the oft-requested photos from the con shortly.) Actually, for logistical reasons, I sent the money to my father and had him make the exchange for me a few hours before our near-midnight arrival in the ATL. (Thanks, Dad.) Interestingly, I never actually laid eyes on the car until after the purchase. I asked a lot of questions of the seller, who seemed very honest about the vehicle's merits and demerits, but it was my former roomate/overlord, Masta, who made the long-distance purchase possible. He gave the car a thorough going-over and test-drive. Since he's a mechanical engineer, a car guy, and a former Miata owner, he was just about the perfect person to inspect the car for me. (Thanks, Masta.) I'd also like to acknowledge JD, from my local Miata club, who also attended Dragon*Con and offered to haul back all the bulky extra bits in his truck. (Thanks, JD.) (Come to think of it, all three of the guys who helped me with the purchase are Georgia Tech graduates. Interesting.)


The "new" car is a 1995 MX-5. Thus, it's a first-gen (NA) Miata with a 1.8-l engine. I've chosen to name her Emma, because the Miata's alphanumeric designation is pronounced "Em Eks Five." The color is called Laguna Blue Metallic, and, as you can see, it's quite attractive. Laguna Blue was only offered in '94 and '95, so it's considered fairly desirable. I didn't buy this car for the color, however.


You see, my plan is to make Emma a dedicated motorsports and fun car, leaving Mia to be my daily driver. By design, no great transformation is required to turn this vehicle into a track rat and toy car; the previous owner---whom I found via Miata.net---was using her for exactly those purposes, and he outfitted her with a number of performance modifications. That is why I bought this particular Miata. The car came with all of the following:
  • Stock seats plus Cobra Suzuka S race seats.
  • Stock seatbelts plus 5-point harnesses.
  • Stock 14x6" wheels with Falken Azeni tires (205/50-14, I think) plus 15x7.5 6UL wheels with Nitto NT01 tires (225/45-15).
  • Stock steering wheel plus a tiny, 280-mm Momo race wheel.
  • Bilstien PSS9 adjustable dampers and springs.
  • Racing beat front anti-roll bar.
  • Hard Dog Hard Core Double Diagonal roll bar.
  • R Speed intake, Jackson exhaust manifold, and Flyin' Miata exhaust.
  • Deleted soft top.
  • OEM hard top, in Laguna Blue.
  • R-Package-style front chin spoiler and rear lip spoiler.
  • Tow hooks.
  • Other assorted goodies.
All-in-all, I think I got quite a lot for my money.


I do have a few things I want to do to the car to get her even more track-ready and to make me more comfortable, but once I get her registered and titled in Maryland, there's nothing stopping me from hitting the track.

Retractable Headlights

...are very distracting.
