This Vette has a lot going on. What exactly are "Hurst Airheart disc brakes?"

Hurst Airheart used to be the only aftermarket brakes available for racing. First choice for rear disks on early top fuel cars rear only setups.

An acquired taste for sure. It doesn't align with mine. There's a lot going on here. The glassed in front spoiler to start.

It's not everyone's cup of tea, but I'm sure it'll make its next owner very happy!

interesting how they moved the brake booster & MC forward. i'm guessing the 572 is a tall deck and interfered with the booster maybe?

I dig it. I like custom Vettes. It's not like someone chopped up an L88, so I say the next owner should keep on customizing it!

I've never seen a rear suspension anything like that on a C3 Corvette before. I wonder if it was custom or a kit from back in the day,

It's really an unusual mix.....custom and race. Normally one or the other...

Kinda looks like someone was spending someone else's money, disregarding cohesion. All that power and suspension, on stockish tires. And...is that a dry sumped differential??

Hurst Airheart
I recall em from karting circa '66 - '67
at the time, they were the cat's meow. But the Italians were quite innovative.

Then: SoCal - IKF class C open. Yup, hand-me-down metalflake Naugahyde leathers.

Dunno what brake's are used nowadays, but I can only think today's rotors would be considerably thicker.
On the larger tracks like Riverside or Willow Springs, terminal speeds were very high.

From what I remember Airheart was one of the first (if not the first) companies making aftermarket disc brake calipers and rotors. I think they've been making them since at least the early 60's, and became part of Hurst around 69 or 70. They made calipers for motorcycles, racing karts, etc, not just cars.

In the early 80's I was crewing for a racer racing an 80 Corvette in SCCA GT1. We had been running stock Corvette D8 calipers on the car for two or three seasons without any issues. Then one weekend at Summit Point WV, we blew out a right front piston seal going into turn 1, sending the car violently off the track to the left. The car was torn up pretty bad, but luckily it was the last race of the season so we had all winter to put it back together. When we brought it out to race again the next spring, it had new Hurst-Airheart calipers on all four corners.
