Hi all,
I have 3x AFCO F88 calipers that are the equivalent of Wilwood Superlites, but you can get these for a better price! AFCO still makes the rebuild kits for these so rest assured they are still serviceable. I have two used and one brand new.
Specs are as follows: mounting bolts are 3.5" apart with 1.75" pistons, and I believe these are meant for 0.810" rotors. You will need the matching brackets, calipers, pads, lines, & rotors to complete the kit for your Miata.
I'm looking to get $90 shipped each for the used ones (lower two in the picture) and $140 shipped for the new one (upper caliper), or I could do all three for $260 shipped. Feel free to shoot me an offer.

 

Having built my own BBK around similar F88 calipers, I feel compelled to add some notes here.

Afco does not list any F88 rebuild kits on their website, where are you seeing new production rebuild kits with seals included? Because I want to keep using my calipers long into the future and as far as I know, any parts you can find for sale are new old stock. The F88s were made for Afco by Stoptech. These calipers were so stupid cheap years ago because Stoptech pretty much shut down after getting bought out, and retailers wanted to clear out stock of NLA parts. Now that Stoptech is formally closed and not just in a downward spiral of private equity style plundering, Afcos source of any replacement parts is gone.

1.75" pistons are a horrible mismatch for the rest of the Miata braking system. You'll get a mushy, ridiculously front biased system if you install these on anything close to a stock braking system. This is not a good basis to get a Brofab BBK on your car unless you're completely re-engineering your braking system.

Also, I'm going to be that guy and point out that your asking price for a single used caliper is for what I paid for a pair of new calipers back in 2023. The rubber seals aren't getting any newer and Stoptech isn't getting any more financially solvent.

 

Appreciate the notes. I saw Vivid racing and beefcake racing had rebuild kits, not sure if they're NOS or brand new.
On pricing, I honestly have no clue where to start as I couldn't find how much they should cost new vs used. I'm always open to offers, and these are still far cheaper than getting Superlites at least.

 

I was interested until I saw 1.75”… I bought these last year for another race car. FWIW I paid $47 each brand new. If they were 1.25” I would’ve paid $260 for all 3…
