I was geeking out on your videos. That big girl moves! Stays nice and flat through the turns. That's a cool track. It's too hot out west for the track. I'll wait for fall. Chuckwalla in Blythe, CA is the nicest track I've been on so far. What's your suspension set up? Brakes? Tires? It looks like you have it pretty dialed in. Gear ratio? Still 350 or stroked? You have a roll bar?
I'd love to get to Chuckwalla, Thunderhill, and Laguna Seca is still very much a bucket list track. West Coast Trackation 2023? Haha. I got into modding this car after living near and driving all the awesome roads around Malibu CA some years back. Mulholland Hwy, Decker, Latigo, too good!
Before I jump into my car mods, I'd say the IRS is an ambitious project that I'd be keen to see done. As far as I know it either hasn't been done or hasn't been well documented at least. While it may not be super necessary for most tracks, it'd definitely be very nice on real world roads, same with rack and pinion steering. Even the best stick axle is still a stick axle. Mustangs finally gave it up after all these years, despite having developed a very very competent stick axle in the prior generation. FWIW, there's some fairly rudimentary techniques to bring some mild camber and toe to a stick axle, but certainly nothing I'd call adjustable, unless you would consider swapping to something like this bad boy:
Cambered Full Floating CV Ball Drive Axle - CorteX Racing
but at that price, IRS swap makes just as much sense to me.....
I'll have to shoot you a PM on all the mods at some point, but it's honestly not that far from stock with A LOT of the basic chassis stuff.

One of my bmx buddies is a drag car fabricator, and built me this nice 4 point roll bar to my specs, so the back seat area is not intruded upon and I can still put all my track junk back there, since I still drive the car to every event. The cargo space is nice!
Here's a link to my rollbar thread:
Hey everybody, figured I'd post some pictures of the custom rollbar my buddy built for me this winter. I use the car primarily for open track road course events and some autocross, and was looking to add some rollover protection while retaining the rear seat area for cargo/spares/wheels/tools...
