I just got the car out for it's first drive for the summer a few days ago.
I added a Bluetooth receiver to my amplifier, This little JL Audio MBT-RX is a clever little devise. I wired this to my Sony amp, and that's that. In other big news, I added an electric fan and shroud to the radiator, and finally painted my fancy custom suspension.
The brake package upgrade is on hold awaiting my machinist to finish the caliper bracket, all the other stuff is done!
Nothing too interesting going on, but it was nice to get it out finally.Last edited by mike343sharpstick; July 21, 2021, 09:24 AM.

I can hear the stereo when driving normally, when I'm pushing the go-pedal, not so much.
The guys that do the machine work, tube bending, and a few other things for me get busy in the summer race season.

They are a great resource, and they are only about 1.5 miles away.
AutoX next month!!
I may go to a heavier front spring? How much camber are you running on your Vette? I'm at about -1.3

Almost forgot, updated engine breather system. When That's done I'll share a picture. I put breathers on the valve covers, works under normal driving, but when I'm wringing it out on the track the open breathers would drip oil a little, and unfortunately they are right over the header. The tubes welded to the valve covers have baffles, but the oil vapor must just collect in the filter and drip over time. Anyhoo, I'll now be running a closed breather/PCV unit on each valve cover to a vented catch tank.Last edited by mike343sharpstick; July 21, 2021, 10:40 AM.

it's such a fine line between what you can tolerate on the street and what is needed for the track. I started at 400# springs, now at 500#... I could do more for track but it'd be really hard to ride in on the street

I have 450# springs now, moving to 500#. More spring should require less camber. I dunno??
what is likely to happen is tire pressure and rebound adjustments... outside of that, I won't have time for much elseLast edited by SuperBuickGuy; July 21, 2021, 01:54 PM.Doing it all wrong since 1966

Just by luck, my car is pretty balanced, so I could easily make it worse.
If anything it over-steers, but with a live axle out back all that can be done is more tire. I did that, and it was better, but I don't have any more room for more tire. I'm trying to improve the bit from when you hit the brake, to the apex.
In CAM-T I'm pretty far off the stupid 4th Generation F-Bodies, all the other old junk I can keep up with.

I have an adjustable panhard bar, single adjustable shocks, and a rear sway bar, but still use leaf springs. Pretty much a copy of the 1970/71 Penske Javelins. It does work very well, when the rear slides it's very controllable. I can adjust the roll center with the rear pahard adjustment, but like you said in you post, there is limited time to make adjustments at an AutoX event aside from shock tuning and tire pressure.
I wish there was such a thing as an autocross test and tune day.
Honestly If I left the car alone and just worked on my driving skill I would get better times too.
