If it was a red Westfield with a black nose, it was probably me. I'm often going thru Carlisle. Some nice roads in Concord & Carlisle, plus good places for ice cream.

Is there a metal supermarkets near you? I've found them really easy to work with. They stock pretty much everything and they'll usually cut any size you need.

I love mine. The only issue is that when we're driving as a group in hilly terrain, I keep thinking to check for the person following at the top or the bottom of the hill. Can't see them then because that mirror really works best in the flat.

Reminds me of a story one of my professors told me years ago about a weekend trip to a Formula Ford race. On the way home on the highway, they were suddenly passed by their own car! It had fallen off the trailer. It was in gear. The magneto caught when the wheels hit the road and started the engine. They weren't sure whether to laugh or cry as they watched it go zooming off onto the median.

As others have already said, your options are: Use a 3rd party controller like the megasquirt. Grab the ECU from the Miata and trim the wiring harness down. In my state (MA), option 1 wasn't really going to work w/o a "crusher car", so I did 2. Trimming the wiring harness down was a bit of a project. Even on an early NA, the ECU cares about a lot of different inputs. It looked something like this while I was doing mine. You'll want a good wiring diagram while you're culling. You can find them here.

So did you vent the sides of your engine compartment? On my Westfield, the tunnel seems to be where all the air from the radiator ends up.

I know Car Builder Solutions has them.

Yes, that was probably me. I get to a couple a year. Always good to talk to a bunch of gearheads.

Mass isn't really that bad, although it a bit involved and some of the steps aren't very clear. I wrote up my experiences registering my Westfield a couple of years ago here. Of course, there may have been some changes since then. I know the state changed contractors shortly after I went through. I expect the new guys have made some changes.

That looks great. Here's the rig I came up with for my Westfield. As you can see, the rollbar's doing a few jobs here. From left to right: GoPro Mount Extinguisher 3rd Brake Light GPS Antennae for the Data Logger I wrote up some of the details of the brake light installation here.

Here's a link to a writeup of the process I went through last year with my Westfield. I do know that a few details have changed since then. The state changed contractors in October, and there were a few tweaks to the process at that time, but I believe it is still fairly similar.

I also built the Westfield kit using an NA I had been driving for years. As Dan said, the kit comes with a frame and a-arms. It does use the miata's hubs. I wrote up some of my experiences here, and I'd be happy to answer any questions you have.

I'm in MA and finished building a Westfield last year. Here's some posts about that project. The registration process was a bit involved, but my understanding is that NH is quite a bit easier. I've been very happy with the MX5 version because it's really easy to find parts and expertise. The MX5 Stalker might be a better choice in the US. I had a couple of rough spots with the Westfield kit about pretty much anything involving LHD and there are a couple of parts which can be hard to find over here. Building it was an awful lot of fun, and finally driving it this year was even more fun. I

NVM, I missed the brooklands screen part.

I would second the mirrors for sevens idea. I really love mine. It gives me a really wide view to the rear without blocking any of the view through the tiny windshield. You can see it in this video my son took, but you can't get a sense of the view because he was in the passenger's seat.
