Update on the Falcon-
With a track weekend coming at the end of October I’ve been attempting to address some issues that I had with the car last outing.
Biggest was the brakes. Although they stop pretty good, after lapping all day they start to act strange. Taking a couple pumps to seat and needing a little more foot pressure to grab hard.
So I’m assuming they’re getting hot, or the fluid is old, or I’m experiencing “pad knock back”. A friend of mine with a 64 post car has been experiencing the same thing. We’re both running the CSRP big bearing spindles. Talking to others running the same spindles he believes the pin on those flexes more than it should when hard in a turn. Moving the rotor side-to-side and pushing the pads outward slightly. Next brake application requires the pads to be “reset” with the pedal.
Anyhow I’m addressing all three theoreticals- bleeding the brakes with fresh hi temp brake fluid, installing brake cooling ducts front and rear and installing spindle “hub spacers”.
The hub spacers supposedly strengthen the spindle pin and prevent knock back. I’ll get back and report on this after the next track day.
Heres some pics:

DRP adjustable hub spacer bought from Street or Track
Short video of the spacer installed and nut torqued. Once its adjusted just right there’s little to no end play, the bearings aren’t preloaded and spin freely. With it installed and torqued it creates a solid “sleeve” through the pin, reinforcing it and preventing it from flexing as much

Driver side cooling duct
There’s a plate sandwiched between the spindle and caliper bracket that has a metal duct where the flexible cooling tube is attached, blowing cool 125mph air on the rotor
There’s a rear drum cooling setup I installed as well… I thought I took pics…I guess not. Couldn’t find ‘em.
It involves drilling holes into the backing plate and bolting on a metal duct attachment. Then running the intakes and flex tubes. I’ll take some pics.
Im hoping to see a difference this next event. I got a set of new Hoosiers and I’m ready to go toe to toe with all the GT350s and Cobras!
I have a new track app called “Track Addict’ for timing and telemetry, and I’m gonna get the GoPro thing sorted out for ya’ll
