The torque values referenced in the linked document are gleaned from Mazda MX-5 factory service manuals, Ford Sierra Service manuals, and from Fastenal's Tension Reference Guide.
WARNING: UNLESS OTHERWISE INDICATED, ALWAYS USE THE MANUFACTURER'S SPECIFICATION FOR TORQUE VALUES. The values provided in the linked document are a guide that I am using to help keep my cheese form hanging in the wind. In the absence of OEM torque specifications, I use the general torque specs from Fastenal's Tension Reference guide. I make no claim as to their absolute accuracy nor do I recommend that you blindly use them in your own project.
This document is a work in progress and will change / expand as the build progresses.

- Front Suspension Arms
- The MX-5 Miata front upper and lower control arms are not handed.
- The MX-5 Miata front wing mounts are handed, the higher side going toward the front of the car. (The wing mount that goes on the right side of the car does have a small notch.)
- Rear Suspension Arms
- The Sierra rear lower control arms are not handed.
- The Sierra rear upper control arms are handed. The control arm with the notch goes on the right side of the car.
- Rear Uprights/Brake Brackets
- The Sierra rear hub carriers are handed. The hub carrier with the notch goes to on the right side of the car.
- The Sierra rear brake brackets are handed. The brake bracket with the notch goes on the right side of the car.
- The Sierra spacer kit is not required to keep the axles from binding, the brake brackets fill that role.

I want to install extended wheel studs on my Zero's rear hubs that match the length and style of the ARP studs I just installed on the front hubs.
- Front Hubs: Mazda NA/NB MX-5 Miata
- Rear Hubs: Ford Sierra

This is me, installing at least one set of front control arms on the Zero. Front driver’s side is mounted and loosely bolted into place with the upright. Pretty straight forward but there were a couple of small issues worth noting.
- The powder coating on the chassis is thick and needs to be cleaned out of the bracket through holes for the bolts to slide through cleanly. I used a 25/64” drill bit. I’m sure there are other ways.
- The lower ball joint did not want to slip into its new lower control arm home without a fight,
- A hole drilled in the lower arm for one of the ball-joint’s bolts is 10mm while the bolt is actually M12.

Cleaned, primed, painted, and cleared the rear brakes. Unlike the front brakes (NB MX-5 calipers), the rears are from Ford Sierra.
The front uprights are NB MX-5 Miata parts. Along with clean up and paint, the tapers for upper ball-joint and tie-rod end need to be drilled out. The Zero Roadster uses 14mm rose joints and hardware instead of tapered ball-joints. Drilling through iron with a hand drill tends to snap drill bits, it's good to buy a few and know you're going to sacrifice one or two in the process.
The holes don't need to be precision fit, you can use fairly inexpensive jobber bits, no need for a reamer. (Because the bits are cheap, buy two.)
