Stuff arrived!

This is another unboxing blog post of stuff I got for the Sprint-T. I sold an article, which is something we writers do to make money. Don’t bother looking for it, I sold it without a byline because I made more money that way (no exposure), and I used part of the money to get parts for the Sprint-T, specifically front brakes. It was an article about computer history told from a first-person perspective, because dangit I’m that old that I can tell history in first person. I did have a computer with Windows 3.1 and before that a TI99/4A, and before that a Burroughs that weighed in just shy of 500 Kg. I also built a C/PM computer that I never got to use because I couldn’t afford the 8″ floppy drive… And those wirewrap sockets also cost out the yingyang.

But anyway, The Stuff! I got the biggest disc brakes I could buy for the spindles I bought way back before I evicted Chris Christie from my neck.
The box that was sitting on the porch.
As you can see I got excited and forgot my phone when I started to open the box.

This was the bottom layer of an incredibly Tetrised packing system.The box that holds the actual discs inside the box everything came in.

And there was stuff inside that box.That is a 12.19 inch diameter vented disc made from a proprietary iron alloy

By this time I had remembered to go get my phone and was taking pictures as stuff emerged from the boxes inside the delivery box. This is the hub.This was the least-blingy option for the biggest brake that would fit the spindles.

The front of the hub free from the plastic bag, isn’t it pretty?You can see the machining marks if you look closely that lets you know this was the as-machined front of the hub.

The level of bling with this part number was very high, but there were options that made this look plain. This was the as-machined back of the hub.Plain anodized and not even polished, I went for function but still, look at that machining.

This is what connects the disc to that gorgeous hub.I'm not sure how they made the adaptor that connects the disc to the hub, but the standard of machining was not as high as those gorgeous hubs.

This is what squeezed the pads together on those gigantic discs.Top view of the calipers in the safety of the storage bag. Gotta keep those sanitary if I want to make consistent stops.

Those pads are going to get really squished by that thing.Bottom view, with bubblewrap occupying the space where the pads go to prevent damage or contamination to the pistons.

Speaking of pads.This is a set of Street/autocross compound pads, near race level performance but with the durability needed for streets and highways

And the box those come in.I don't know if you can read that compound label from this angle, but that's a box

The unsung heroes of any build, the hardware that holds it together.Nuts and bolts without which this build won't get built.
Yeah that picture was taken in kinda low light and brightening it up enough to make it look the same as the others caused a loss of quality in my picture program.

And the bracket that holds the calipers to the spindle.This is a high-precision part that keeps things from rubbing together until it's time for things to rub together.

And those are all the pictures, but not all the post.

Besides being the biggest brake kit that would fit the spindles, this is also the biggest kit that would fit inside a 15″ wheel, meaning that’s the smallest wheel I can run. But if I’m serious about running Goodguys I can’t run anything smaller than 15″ anyway because that’s about the smallest wheel they still build high-performance street tires for. So, there are a few 200 treadwear rated tires in 15″ but the widest is 245mm section width and about 23.5″ diameter. Good diameter, but a bit skinny for hooking up 300+ HP coming out of a turn, that’s good for making smoke but not so much for going fast. My next choice is 17″ diameter wheels that have tires available up to 315mm section width but unfortunately 25.5″ in diameter. This is bad because extra diameter means more inertia to speed up or slow down because the inertia varies linearly with weight but as the square of diameter and did I mention the tires get heavier as the diameter increases? And I have been picking over the data from the LS Miata swap forums because same engine same power level and similar tire sizes, but I will have a much lighter car than a LS swapped Miata.

So, I need to get up before noon tomorrow but I’m having a heck of a pollen problem. and so is Mrs. the Poet, and she snores when her allergies kick up which makes catching Zs in the same room a bit of a challenge. I think I’ll hit the diphenhydramine and try to sleep on the other room with the alarm set to get me up, and put the post and me to bed.
