Mmmm inboard brakes are one of my favorite things. I wish I knew why they went away, the only thing I've read that makes sense is that fully reversed torsion is just hell from a metal fatigue standpoint.

Continuing the thread drift, inboard brakes in F1, circa 1977 (Lauda's Ferrari).

Working on an old, creaky XKE with a friend back 25 years ago, I learned why used Jags were so cheap. Absolute nightmare to work on.

Would love to see a race prepped version. I envision a cleaner, lighter overlay with holes drilled out for spot welding. Using the original load points but just adding another layer for ridgidity makes sense to me.

Adding a boat anchor to the front of the car... not high on my to-do list. Heavy for the sake of being strong is appropriate for... tanks. Not Miatas. A good design from a performance perspective balances strength with weight. Hint: plate steel is the wrong approach. IMO saying it's made by an offroad-focused company doesn't justify anything, the GOOD off road race stuff still keeps a close eye on the weight of things, just scaled up for the higher loads of the heavier vehicle, because the lighter vehicle is faster, regardless of the terrain.

the 4 wheel drive class is really small. most trucks and buggies are 2wd. the reverse torsional loads destroyed axles in a short time when a few teams tried inboard brakes.

the hardcore crowd do not run these. Adding weight up high and forward is not something they do. A cage stiffens the chassis many times over any gains these might give you. Besides, these claim to stiffen the chassis for “better steering response and front end grip” meanwhile the floppy, hacked up CSP cars are seeing nearly 2G sustained. They’re all stance points and car-show sticker swagger, no real performance benefit. I’ll admit they may make a difference in ride quality/rattlyness but nobody here gives a fart about NVH. We’re here to go fast.

Comparing a CSP car that drives around on a billiard table surface and a track car that jumps curbs and expansion joints like the ones at Sebring kind of doesn't work for me. What I know about the sloppy dick Fox body Mustangs is that you can only tighten up the suspension so much before the body flexes when you go over bumps and the suspension doesn't move. It doesn't mean they can't achieve 2 G's of grip, it just means you cannot tune the suspension properly anymore.

Those do seem like they would help a lot, but the miata is already on the low and not the easiest to get into
