I loved the Magnaride with the stock springs and I would probably not make any more changes after Mr. Johnson's tune........but then I drive over every curb imaginable and I thought the factory recovery with a HP Mach 1 was great.

I see you're running the BMR 250/980 springs. I have the same springs and they still feel too soft without aero. How are they holding up with aero? Does your splitter take a beating?
(Also, did you have to retro fit the Verus GT350 splitter to fit on your Mach?)
Also the splitter is still not as low as I need it, so no, it hasn’t taken a beating. Plus @flyhalf sent me some awesome splitter protection widgets, which I’m using on the front corners.

Getting the OP Mustang hubs/studs is a convenient and smart way to go in my estimation. The ability to rotate all around is so much more efficient for tire life, just remember to do it often --- at least once per track day. Little secret is to do it before leaving on the second track day as many forget and then they hit the next track day with everything in the same spot. A little track journal is really the best way to keep current.
I go with the paint marker pen on the tires method. I’m running various sets of @Apex Wheels and tires, so I’ve been swapping them around like crazy. Trying out Pirelli DHF, Michelin SM8/9. Then I’ve got a wet set of Michelins, and finally a set of SC3r on 19” wheels. Needless to say the 19” wheels have not been on the car for a while. Once I went 18” and slicks, there’s no going back 😬

Here’s a couple of laps at ECR last month. Both in the 2.06 range. Hitting traffic and cold/green track, so should easy knock some time off that. I’ll be back there 2-3 March with CHIN to see what I can do.

Thanks for your input. I appreciate the response.
Honestly, I think we are just messing around on these aftermarket springs until we go to coilovers. I haven’t made the jump yet, since I’m still undecided if the car is going to continue its development versus buying an actual built track/race car.

I hear ya.
I want to add aero to my car but I need coilovers first but I'm also thinking that $3-4k for coilovers would be better spent on actual racing school. Driver mod > suspension

Second the racing school and where you are located I would look into the Ron Fellows school over in Pahrump, NV. The best track ever was when Ford was at Miller ( Utah Motorsports Campus ) but now the options and track safety are really good there in Pahrump.
