I'm currently running an ST40 BBK with Wedsport TC105X 17x9 +49 wheels, 255 square setup. Fenders are rolled, dropped 1'' on Ohlins DFV.
I absolutely love this setup for the track, but the tramlining on the street with the square setup is really ruining it for me. I only do 3-5 track days per year, so to compromise the car all year for that.. eh.
I also love the AP2 V1 wheel look, so.. I'd like to see if I can run the OEM wheels with spacers for the street, then swap to track wheels when I need to. It looks like I'm going to need 20-25mm spacers on the front to clear the BBK with OEM wheels.
Is it better to have extended studs with regular 25mm spacers, or run the bolt on spacers with their own studs integrated into them? Can you recommend highest quality parts for this setup?
Or is this just an un-safe setup to begin with? I'm concerned if the spacer/OEM wheel combo will be stressing the extended studs too much. If the above situation with the OEM wheels will be unsafe or "weaker" in any way, then I'll just abandon the idea.
Personally, I would go with extended studs but that's 1) more expensive 2) a pain in the ass to do in regards to removing the knuckle. When you get extended studs you also want to look into open ended lug nuts which is an extra unplanned cost.
Since you're planning on only street use, the easier option is to simply use bolt on extended studs.

I'd rather do the 100% solid setup, regardless of cost. The removing of knuckles will be a pain but something I'm willing to work through.
I already have the open ended 949 lug nuts for my current track wheels, so all good there.
My research has led me to believe that as long as I'm using hub centric spacers and extended studs, there is no more stress on the studs than without the spacers, so I'm probably going to go that way.
Now just a matter of figuring out how much spacer I'll need with AP2 V1s on the front with the BBK.

Also, totally off topic, but I had the first 899 Panigale delivered to the state of PA and I miss it dearly. It was my first Duc after a string of japanese bikes... what a wonderful machine.
I always took the idea of running spacers with either integrated studs or not, being unsafe with a grain of salt. Ran either option through periods of years owning this car, and even the less expensive options found on ebay/Amazon, never an issue. Is it ideal? no, but doesn't mean its unsafe. They sure are useful though. Just make sure they are quality and torqued down properly, check them on occasion if it gives you piece of mind. I never had any come lose on me once I tightened them down however.

I run the H&R DRS Spacers which come with extended studs, the kind that replace the studs in the hub so you would need wheel bearings too . Pn 3065640 and 3067500 both 15mm. Works perfect on my stock rear quarters and rolled fronts with ST40 front and ST22 rear. At 3 deg camber front and rear i used an additional 5mm 1065700 on the front to make the fitment look normal. i needed the 5mm originally for my track wheels to clear. The studs that come with the kit were the right length to use the oem lugs but i needed open ended ones for the track wheels.

It's definitely the perfect blend of the best riding and looking Ducati ever made. I prefer its riding over the 1199 and the looks over the 959/1299 and the new V series. Glad Ducati still makes such a wonderful machine, unlike Honda which no longer makes an S!!

I also just sold my 2001 Ducati 750 Sport over the summer. I believe the ST and the Sport were from the same frame. Good raw machines.
I still run spacers on my Honda Prelude's wheels. I've had them on for over 15 years with no issues when street driving.
